Adding a PoE Switch to existing Network

Hello,
Currently we have a Linksys RV016 router with 3 Linksys SRW224G 24-Port Managed Switch. Can I add a PoE switch to my existing setup without any problems or I can only add none PoE switches?
If I can add a PoE switch is there a specific configuration or just plug and play?
Thanks,
B

Yes you can connect a PoE switch to the SRW224G switches but you will need to connect the PoE switch to a power supply. The only way that PoE (Power over Ethernet) will work is when you connect the PoE switch with another PoE switch. Only in this scenario, you won’t need to use a separate power supply for the PoE switch to work because it is getting its power form the first PoE switch / router.  
Regarding if this will just be plug and play, it won’t be plug and play. If you have set up VLANs or other crucial settings in the other switches and you want it to manually set the PoE switch depending on the limitations you want for these PoE switches.

  • Adding Airport Express to my existing network

    I'm sure this has been covered, but I've been wading through the various posts on AXpress and I have just become more and more confused with the different scenarios that people are presenting....so here's what I want to do.....
    I currently have a G5 connected to a Belkin wireless router that also has 4 ethernet ports. The G5 is connected to it via ethernet. My Netcomm ADSL modem connects to the Belkin router and I have a Macbook connected wirelessly. I also have a Belkin Wireless Range Extender that picks up the wireless signal from the main Belkin router and repeats it so that I have great wireless signal no matter where I am in my house. All of this works flawlessly, and has done so for the last 2 years.
    Now I want to add the AXpress that I have just purchased purely for the Airtunes feature. Can I just add it in to the existing network without changing what is already working perfectly? I would imagine that I should be able to use either my G5 or my MacBook to stream iTunes music to the AExpress?
    Could someone either tell me how to, or point me in the direction of a post that deals specifically with this type of set-up?...I would be most appreciative, as I said, I was just becoming more confused as I read the existing posts.
    Thanks in advance.

    I am in the same position that you are, except that I have already been using the Airport Express for itunes for nearly a year now and it works great. I called Apple to get it working and it worked fabulously in my old apartment. However, I want to use it with my new wireless set-up, which works great in my new apartment. I just want them to work together....
    I have a linsky wireless WRTP54G for my RCA broadband router that came with my DSL. When I use the airport utility to scan for this "base station" as the instructions for creating a WDS say to, I can't find it. Actually, the computer can't find it and I get an error. I am pretty sure that I have the right IP address and that the password is correct, because I just reset it through linksys. I think if I could just get past this step that I could continue on.
    Does anyone have any advice?

  • Adding a new switch to the network....configuring internet access

    Hey guys i need some help!
    I am trying to set up my first switch. I am using the catalyst 2950 for learning on. 
    The network im on right now (the one with internet) has the following settings. 
    10.22.227.???
    255.255.255.0
    10.28.43.254
    The one i am learning on i connect to it by going to 192.168.0.1 this will allow me into it using the Cisco Network Assistant.
    I have a laptop on port 1 using Vlan1 and i have Desktop on port 24 with vlan 1 and i have a cable from our 10.22.227 network pluged into port 23
    I am able to see the computers and i can share files on it. What i dont understand being a noob is why i dont have any internet on ether computer. 
    I have setup up port 23 as a switch. 
    It seams like to me i would have to give the switch a ip address a subnet mask a default gatway and a dns of the 10.22.227 network on port 23.
    Can some one throw some light on the subject and point me in a good direction?

    @de fl
    If i go to a computer on the 10. network i can ping and go out and do everything i need to. 
    But if i try and ping with in the new switch (192) it does not work. I have added an ip address and a default gateway I have added a screen show on how our network is set up. 
    To me i think i need to add a ip address subnet mask and default gateway to the switch for the new switch to work. 

  • Adding Airport Extreme (n) to existing network

    Hi, I hope someone can help!
    I bought an Airport Extreme (802.11n) hoping that I could connect it into my existing wireless network and use it to provide (wireless) access to a 400Gb USB disk and a Canon Printer.
    I have experimented with it a little to establish that the disk and the printer would play ball. They both work via the Extreme ONLY when I access the base station directly, ie in a different network. Problem is I want to be able to use things like iTunes from the internet on a different network and use the 400Gb disk for the downloads! (Phew that's the scene set)
    My existing wireless setup is: Linksys WAG300n wireless adsl router which allows access to the internet for my macbook pro and my son's and daughter's winxp machines.
    To date I have tried setting the network up using the linksys as the dhcp server (as it usually is) and then with the Airport Extreme as the DHCP server (with the linksys dhcp server off). I am now ABSOLUTELY out of ideas.
    Is what I want to do impossible or not? All I want to do is have the Airport Extreme sit within my wireless network providing access to disk and printer. I actually don't want it to act as a base station at all (right ??). Can I get the extreme to act as just an access portal to another piece of equipment?
    btw the linksys WAG300n is not WDS capable so I can set up a "backbone" which I guess would be the ideal way to go.
    btw (again) I have looked through this forum and haven't seen anything that immediately looks like the answer to me, so I apologise for my dumb question if it has been answered before.
    Hope someone can shed some light on the problem!

    Sorry but that is ONLY possible if the main base station supports WDS.

  • AirTunes on Windows PC, no existing network/router.

    I want to set up my AirPort Express to stream music from my Windows PC in one room to the stereo in another (it's a small apartment, and the APE is definitely in range). That's all. I have no existing wireless network set up, and no router.
    So far, I have gotten it to MOSTLY work, but it was only playing half-second snippets sporadically. The connection is strong, but it does seem to drop out a bit, although I can't tell if it's a problem that would affect the music streaming, as I haven't gotten it to work yet.
    The only adivce I can find anywhere about this problem is pertaining to adding the APE to an existing network - is that the only way this will work?
    Thanks in advance!

    Dr Van Halen,
    I just asked about the same questions in my post. Were you able to get your music streaming from your PC to your receiver through just your APE or did you have to add another device to make the wireless connection.
    I'm just confused as to how the APE streams music from your PC without a wireless device between each other?!
    Thanks,

  • Help airport express won't connect to existing network

    Hi,
    I have a simple setup. I have a Netcom wireless router/modem/VoiP and a Macbook.
    A few months ago I got a airport express so I could play itunes on the stereo.
    I set it up fine adding the AEX to the existing network. I moved house and the net was off for 3 weeks so I reset to AEX as a standalone network so I could still play itunes.
    Now the net is back on I cant get the AEX to connect to the existing network again. When I set up the AEX it updates the info but, then when it resets, the Macbook just can't find it anymore. Nothing I can do will make the macbook find it except doing the hard reset (paperclip in the side) and then of course I am back to stage 1.
    I am sure I have the network password correct (WEP) and I have tried all forms of resets - please someone help!
    cheers,

    I am having a similar problem using my new Airport Extreme. Got one express working for a printer, but second one (to play I-tunes) sets up, but then gives error message "Unable to find base station after restarting." Have done repeated re-sets.

  • Use wireless router with existing network and switch?

    I have an existing network using a T1 into a switch; all the computers and the server are connected to the switch. Some distance away, via ethernet cable to the switch, I would like to connect a wireless router, one computer wired to that router, and other computers connect via wireless. Our server provides DHCP. Is this possible? How best to do it? Which Linksys router would be best for the purpose? Thanks for the help!

    The "correct" device to use would be a wireless access point like the Linksys WAPs and not a WRT router. WRT routers are supposed to connect to the internet on its own.
    You can set up a WRT router as simple access point. see here for the setup.
    The best router is the one which best suits your needs. All wireless routers and access point provide wireless access. It depends on what you want (802.11n, 11b, 11g, range, speed, etc.). The newer routers are better from the specifications but usually also have more firmware bugs. But that's pretty much all one can say based on your generic requirements.

  • I'm trying to extend the range of an Airport Extreme 802.11g by adding an Airport Express 802.11n. I set the Express up to join the existing network, but it does not make any difference in the range of the network. What's wrong?

    Let me see if I can help you with the basic WDS configuration steps:
    Note: To help facilitate the setup, temporarily connect the AXn directly to the AEBS LAN port using an Ethernet cable. Once the setup is complete, you can move the AXn to the desired location. For all configuration steps you will be using the AirPort Utility. Before starting, be sure to jot down the AppleIDs for both base stations.

  • Adding Airport Express to an existing Windows WEP enabled wireless network

    I have can't find anything to help me add my new Airport Express to my existing WEP network. All I want is to use to play my Itunes through the sitting room stereo. I've upgraded the firmware on my Netgear 802.11b wireless access point so I can have a 13 digit WEP password. I've installed the latest install software from the apple website for the express box.
    I can access the express box fine on its own but not add it to the existing network. Now the only thing that works is the apple connection! My old wireless network has stopped working. I tried the same at my office yesterday and the only way to resolve the situation was to uninstall all the Apple software and then my Wireless network was able to work again. I'm pulling my hair out here and getting in to trouble with the rest of the family because it is taking so much time up!
    Someone mentioned somewhere some new firmware - I can only find one for MAcs not PCs - I don't have any Macs on my network.
    Please help.
    THANKS

    Make sure you have installed at least Airport 4.1 on your PC:
    http://www.apple.com/support/downloads/airport41forwindows.html
    Most Netgear wireless routes will tell you the hex equivalent of the plain text WEP password you enter into it - and this is found using the same web browser based process you use to configure the router. This information cannot be found by any other means (like "pinging" the router's IP address). If you can get the WEP key in this manner, configure the Airport Express with the same WEP key *while it is still cabled to the router*.
    The alternative is to come up with a 26-digit hex format WEP key of your own choosing. You can then wirelessly access the Airport Express and enter that WEP key on it first, followed by doing the same on the router second.

  • Adding new switch in my network including Cisco Prime Infrastructure

    hi all,
    if I connect new switch to my network, can I let Cisco PI to apply a specific template of configuration to this switch automatically?
    how can I do that ?
    thanks in advance

    Hi,
    i followed these steps :
    SWITCH SIDE
    - configured Prime Infrastructure as snmp-server host;
    - enabled snmp-traps for linkup and linkdown events globally;
    - disabled snmp-traps for linkup and linkdown on non relevant interfaces using the no snmp trap link-status command
    PRIME INFRASTRUCTURE SIDE
    - under "Deploy/Monitor Deployment" i deployed template "Interface Health"  for all the interested switches
    -  under "Administration/System Settings/Mail Server Configuration" configured my internal SMTP server to make Prime Infrastructure able to send e-mails
    - under "Operate/Alarms & Events" click on "Email Notifications" , then on "Switches and Hubs"
       - check the "critical" box ,  insert the destination e-mail address into the "To" field then click "Save"
     -  check the "switches and Hubs" box and then click Save
    As i know is possible to avoid to configure every single not-interesting port on the switches with "no snmp trap link-status" command (it's a bit annoying when you have tens of switches), using Port Grouping configuration on PI but i tried it without success.
    Hope this helps.

  • Adding a new Airport Extreme to existing network?

    Hi, I just bought an Airport Extreme, which I want to use in my apartment to replace my existing Airport Express (802.11g) network.  Is there an easy way to do this without having to reset all my devices that use the network?
    I have a TV, receiver, Blu ray player, two laptops, two iPhones and an iPad, all of which would need to be reconfigured if I just scrap the existing network in favor of the new device's new network.  (And it's really annoying to set up the network on the home theater stuff!)
    Am I just being lazy, and I should just start a new network from scratch?
    Thanks in advance for any help or suggestions.

    Whenever replacing network equipment, it is always a good idea to start from scratch. What you may save during the initial setup may be lost with the time you will spend hunting down why things are not quite working right later.
    I would recommend that you do the following as a minimum:
    Power-down the modem, AirPort base station, and computer(s).
    Disconnect the 802.11g AirPort Express Base Station (AX) from the Internet broadband modem.
    (OPTIONAL) While all of the devices are powered-down, perform a "factory default" reset on the base station. This will get it back to its "out-of-the-box" configuration and make setting it up much easier, especially if you use the "Assist me" process within the AirPort Utility. (ref: Resetting an AirPort Base Station or Time Capsule)
    After the base station resets, go ahead and power it back down.
    Connect the new 802.11n AirPort Extreme Base Station (AEBSn), using the same Ethernet cable that was used for the AX. Make sure to connect the cable to the AEBSn's WAN (circle-of-dots) port.
    Temporarily connect your Mac Pro to one of the available LAN (opposing arrows) ports on the AEBSn. Of course, if you intend on leaving the Mac Pro connected by Ethernet, then just leave the Ethernet connection as is after the setup is complete.
    Power-up the modem; wait at least 10-15 minutes to allow it adequate time to initialize.
    Power-up the AEBSn; wait at least 5-10 minutes. Note: The AEBSn's status light may continue to flash amber after it has intialized. That is because, there may be some additional configuration items necessary, like setting up wireless security, before the overall setup is completed to get a green status.
    Power-up your computer(s).
    In this basic configuration, the AEBSn will broadcast an unsecured wireless network with a Network Name (SSID) of Apple Network NNNNNN. Network clients, connected to the base station either by wire or wireless, should now be able to access the Internet through the ISP's modem. Once Internet connectivity has been verified, you can use the AirPort Utility to configure the base station for wireless security and any other desired options. Please post back your results.

  • Time Capsule Questions....Joining Existing Network

    Firstly, the below questions are based on my assumption that the Time Capsule's firmware & hardware is similar to the Airport Express (but with the addition of the HDD!)
    The router my network's running off is a Linksys WRT600N (has both 2.4Ghz & 5Ghz and 802.11b/g/n).
    I'm interested in adding a Networked hard disk to the network (not through using the router's USB port) for the sole purpose of Time Machine backups.
    From what I know, Time Machine doesn't work with NAS's apart from the Time Capsule (which from looking at it, would be a waste of money as I don't want to use it as a router.)
    From what I've read, the Time Capsule can be connected by ethernet to the existing router (or switch), and have all it's Wi-Fi & routing functions turned off - making it only work for it's NAS HDD (that'll work with Time Machine.)
    Now that seems like quite a waste of money on a £200 device that has WiFi etc built in.
    Now, thinking about it, one of the locations I'd put the Time Capsule when connect as above, has bad wireless reception......
    From what I've read (especially this thread), when the Time Machine is connected as above, and I disable the Time Capsule's built in router and DHCP server, it can be assigned a different SSID (my network already has 2 (one for 2.4ghz & one for 5ghz)) and it'll be broadcasting without interfering my existing network.
    My wireless devices could be given the Time Capsule's SSID & encryption details, and would be able to connect to that or the Linksys (depending on where abouts in the house they were) - and as both networks are connected together, all shared HDD's and internet would work fine joining together over the three SSID's from the Linksys & Time Capsule.
    The tricky bit, is there a way of having the Time Capsule repeat/boost the signal coming from the Linksys? (instead of broadcasting on a different SSID, it'd be acting as a Wireless Access Point).
    From my research about repeating, I know that WDS is needed, and accoring to here[ the Linksys WRT600N supports it. (whatever it actually is!)
    So, would the Time Capsule be able to repeat/boost the Linksys's signal? If so, how? (I'd keep the two router's connected together by gigabit as obviously the location of the Time Capsule would be one where the Linksys's signal struggles to reach.)
    Anything wrong with the idea of broadcasting on a different SSID? And any ideas about broadcasting on the same SSID?
    Blimey that's a long post! If your still reading this far and understand what I'm on about you can have a cookie
    Thanks
    Ed.

    Westyfield, Welcome to the discussion area!
    The tricky bit, is there a way of having the Time Capsule repeat/boost the signal coming from the Linksys?
    Your scenario has Time Capsule connected via Ethernet to the Linksys. To extend the Linksys's wireless network, simply configure the Time Capsule to use (a) the same SSID as the Linksys, (b) the same encryption type/level/password as the Linksys, and (c) a channel as far as possible from the one used by the Linksys.
    For all wireless clients there would be one big wireless network.
    There is no need for WDS.

  • Can anybody help me to access Internet with my existing network

    Dear All Recently I purchased new WRT 54G wireless router. Also I have tied up with new ISP to give wireless internet access to some of the my Higher authority employees only. My office network setup is as shown below Local Ip range : 172.18.0.0 to 172.18.2.254 subnet mask : 255.255.0.0 Default gateway : 172.18.0.50 Wireless Router configured as : 1) configured all ISP settings 2) configured LAN site setting( But I had to setup lan as 192.160.1.X i.e the required by ISP ). 3) connected ISP lan port of WRT54G to cable coming from ISP Modem 4) Connected Local port( any one of 4 ports) to my existing switch(existing LAN----172.18.x.x network) Now suppose I configure user laptop to access new ISP internet through wireless.I have done following setting Wireless LAN setting : Ip address : 192.168.1.2( I can give any IP of network 192.168.1.x) subnet mask:255.255.255.0 Default gateway :192.168.1.1 DNS : Automatic I can access the new ISP internet without any problem with WRT54g router. But the problem is while accessing the new ISP internet( Using 192.168.1.x/255.255.255.0/192.168.1.1 network),Also I want to access my existing network( 172.18.0.0/255.255.0.0/172.18.0.50). Since I am very weak in routing the network, can anybody help me out to do routing setting in linksys WRT54g router so as to access my New ISP internet using existing network( 172.18.0.0/255.255.0.0/172.18.0.50). Please help me anybody

    O.K. Still the crucial question remains whether you want the separation of the ISPs enforced or not, i.e. do you actively want to prevent someone to switch to the other ISP simply by reconfiguring some settings on the computer or not?
    If you don't want to enforce the policy and it is enough to just use different IP settings on different computers then this would probably be the easiest solution.
    If you can, install a DHCP server (e.g. on a Linux box) inside your network which does the DHCP address assignments. That way you can dynamically assign the proper addresses to the computers.
    You can then assign the WRT an LAN IP address inside the 172.18 subnet. The DHCP server assigns anyone addresses inside your 172.18 subnet. However, you configure different gateway and dns server addresses depending on the computer. You configure the MAC addresses of those 'preferred' laptops the gateway address of the WRT and the public DNS servers of the new ISP. All other computers you assign the old gateway address of the old router and the DNS server addresses of the first ISP.
    If you don't want to install your own DHCP server you can assign either pool static IP addresses, i.e. assign all preferred laptops static IP address including the gateway address of WRT and use DHCP only for the normal computers or vice versa.
    What won't work reliably is to run two DHCP servers on both routers and connect the LAN of both together. You'll end up with computers picking up the wrong IP address from the wrong DHCP server.
    Again, this separation only happens due to the different configuration of the computers. If anyone can freely reconfigure the computer he has it is easily possible to change the gateway address and thus swap the ISP. But as long as people comply with the rules it works.
    If you want to enforce the separation you will have to install another router between the two gateway router. This third router passes traffic from the WRT subnet for the 172.18 subnet and accepts the return traffic. In the opposite direction the router does not forward traffic. You should even be able to use a standard NAT gateway router and hook up the internet port to the 172.18 subnet and the LAN port to the WRT. You then configure a static route on the WRT to forward packets for 172.18 subnet to the third router. If the third router does not NAT then you have to configure another route on the first router to forward traffic for WRT subnet (192.168.1.*) to the third router as well.

  • Airport Base Station - setting up base station to already existing network

    Hello,
    I just replaced a network switch on the network. Since I did that I am unable to get Internet connection from our main base station in the server room that distributes the IP addresses. I did a reset to the base station and tried to get it to show on the already existing network, but I'm having some issues getting the base station configured with the other base stations on the network. How do I get this main base station to show up on our network?
    Right now our other base stations are not getting valid IP addresses. The base station that is setup to distribute IP addresses is getting valid addresses from our provider. If someone could give me any suggestions I would appreciate it.
    We are running Apple 10.2.4 on our network.

    OK - starts to make sense now. If you did a factory reset of the base station then more than likely the airport network name for it is the Apple default name, and you probably lost the WDS in Wireless Mode.
    Do you know the old network name and the network password? Do you know how the other 4 or 5 base stations were configured - ie as a WDS network and whether as relay or remote base stations. You should not need to change anything on these base stations if you know how your AEB (main) was setup in the first place.
    One step back from this, you need to confirm that the DSL modem is connecting to your ISP. Connect the ethernet cable from the DSL modem to your Mac and confirm that you can log onto your ISP or internet. If it works then lets go onto the AEB you reset.
    Apple publish setup manuals for their AirPort Base Stations - they can be downloaded at: http://support.apple.com/manuals/#airport
    1. Reset your AEB to its factory default again.
    2. Turn-off the AEB and connect one of its ethernet ports to your Mac by ethernet cable, and connect the DSL modem to the WAN port on the AEB by ethernet cable.
    3. Power up your Mac, the DSL modem and the AEB and wait for all to complete their startup sequence. Then open AirPort Utility - you should see your AEB under a generic network name. Click on the AEB.
    4. Use the auto setup procedure by clicking 'Continue'. Follow the onscreen instructions for setting up a new network. When asked, use the 'original network name' for your school network. When asked for a network password, use the 'original network password' for your school network (what sort of network security were you using - WPA2 Personal - use whatever you had previously.
    5. At some stage you will also be asked to give the AEB a name and admin password - use whatever they were previously.
    6. When the setup procedure is complete and the AEB finishes restarting, the AEB will reappear in AirPort Utility. Click on the AEB and click 'Manual Setup'. You may be asked for the admin password to get into the configuration profile.
    7. Click on the 'Wireless' tab and set the 'Wireless Mode:' to 'Participate in a WDS network' if not already set to this. While in this pane, look at 'Channel:' - do you remember what this was set to previously (if not, you may need to connect one of the other AEBs by ethernet cable to a Mac and use AirPort Utility to check the Channel setting.
    8. Now, click on the 'Internet' icon at the top of AirPort Utility. Check that 'Connection Sharing:' is set to 'Off (Bridge Mode)' - if not, change it.
    9. Now, click 'Update' and wait for the AEB to restart.
    10. Now, disconnect the ethernet cable from the Mac to the AEB ethernet port.
    11. Open Airport Utility, and hopefully, you can now see the AEB and the other 4 or 5 base stations.
    Let us know what happens.

  • 310N extending an existing network

    I am trying to extend my existing network. I currently have the cable modem plugged into an older Linksys wireless router which works fine, from there I have wires going out to other parts of the house and a Linksys switch providing extra ports.One of the wires goes to the office upstairs, where I am trying to install a 310N to extend the reach of my wireless. I am willing to set it up as a separate wireless network.
    I plugged the 310 into the switch and I got an IP address for a second, but I couldn't ping down to the first router from the computer. I reconfigured the 310 putting it on a different subnet, connecting the cable from the downstairs router to the WAN, to a normal port. I could not get it to work. I am fine using the 310 as a switch or a hub, I just need the extra wireless coverage.
    Any suggestions?
