    what is the chance of cisco 3750x 24 port poe switch failure? is backup necessary for this ? please answer me in details.

    If you have a Cisco switch with, at least, one faulty port you RMA the appliance.  
    There is nothing more detailed than that.

  • Catalyst 3560 24 port-PoE switch powers on but no STAT LED and console not responding

    I rebooted my Catalyst 3560 24 port PoE switch and when it turned on only the STAT LED went green the other LEDs are off.  I get no response from the console port using putty and the cable I used before this happened.  I tested the cable on another switch and it works fine with putty.  What can I do with this switch?

    This unit was purchased before I came to our company.  There is no support or maint contract.  I'm sure the unit is several years old...we'll call the vendor and see what they'll do..not expecting much.

  • My SGE 2000 24 port POE switch won't boot

    Hi,
    I have a sge 2000 24 port POE switch that won't boot, won't communicate on console or TCP/IP, and all of the port lights are lit up green. Holding down the reset button doesn't fix the issue and there aren't any lights illuminated on the left hand side of the switch. Do I have a future doorstop?
    Any ideas?

    Hi David, if you're unable to console the switch, there isn't an alternative recovery method. You should check the warranty by calling the SBSC to see if you're entitled to replacement.

  • ESW 520 8-port PoE switch cannot ping

    Hello
    I have an ESW 520 8-Port switch with a management ip address of 192.168.10.2 /24
    After I reboot it, I can successfully ping it from a pc with an ip of 192.168.10.123 for about 50 consecutive times.
    After that, I get a "Destination host unreachable" (this icmp message is sent by my pinging pc (192.168.10.123).
    This obviously seems like a bug.
    Has anybody seen this before.
    Whenever I reboot it, it goes through the same sequence.
    Thanksj

    Hi David,
    I figured out what the problem was.
    The switch was obtaining an ip via dhcp, as it is a DCHP client by default.
    I am used to working with Enterprise level Cisco equipment, so this simple oversight was the cause of the problem.
    The ip that was obtained via dhcp was obviously different than the default ip of 192.168.10.2
    So when the switch was rebooted, it would start off with its default ip of 192.168.10.2.
    As soon as it obtained an ip via dhcp, I could not ping it of course
    Thanks for the  input though

  • Using 3560 8 port PoE to power up 1252 dual radio AP for b\g clients

    Hi,
    We have a couple of 3560 8 port PoE switches that we plan to use to power up 1252 APs (not ordered yet). Now since the 3560 switch will only support one radio, is it possible to order a pre installed dual radio 1252 AP, disable the 5 Ghz one and enable the 2.4 Ghz, so that b/g clients can access the network, until a PoE+ switch is purchased?
    All help is appreciated
    Thanks

    Slight misconception here.  The 3560 will power the AP and both radios, so long as you are running 4.2.112.0 or higher on the WLC, or 12.4(10b)JDC or higher for an autonomous AP.  The caveat here, is you will run in a degraded state for N rates.
    The below link describes the power to N rate relationship:

  • 8 port poe with 2 SFP 1gig uplink port

    I need a 8 port poe switch  (LAn base) with 2 X 1gig SFP uplink.  can anyone suggest me the correct model?

    Depending on your budget, you have a choice of FastEthernet or GigabitEthernet ports.
    For FastEthernet ports, WS-C2960C-8PC or WS-C3560C-8PC.
    For GigabitEthernet ports, WS-C3560CG-8PC.

  • Single port forwarding with a E2000.

    I was wanting to port forward a port that was 25565 for a game of mine, but everytime I try it won't work. someone give me a walk through?
    By the way, it's 7AM and I didn't sleep yet so i'll explain more detailed in the morning.
    I'm using a E2000 Router.

    Best thing would be to set a dhcp reservation for your pc/notebook and then set the port at the single port forwarding page to your int. IP.

  • Powering AP's via POE switch or injector

    Hi,
    Could anyone please advise if there is any difference in the power supplied to a 1142N AP when using a power injector (AIR-PWRINJ3/AIR-PWRINJ4) compared to using poe on the switch port (2960S 24 port POE switch WS-C2960S-24PS-L).
    Thanks.

    but someone once advised that in order to get full N potential from the AP's you need injectors.
    Someone got their facts wrong.
    If I was to get the full potential with N, I'd look to plug the WAP into a GigabitEthernet port.  PoE or Injector won't make any difference.

  • Cisco 3750x switch. Turning off a port at night

    Hi everyone,
    I have a question regarding power management for the Cisco 3750x Switches. Is it possible to power down switch ports
    automatically at a specific time and if so how. I would like several Ports to be powered down between 2 and 3 o clock at night.
    Can anyone tell me how i can realise this? (these switches have Energie Wise capabilities)
    I hope to hear from you soon.
    Thanks in advance!
    Kind regards,
    Wouter Platteeuw

    few things to try:
    Go to your email setup, go to the account in question, go to filters, Check the box that says "do not forward messages to the device" Set this back to the default if this doesn't work.
    Something else:  try using the blackberry firewall

    I think this will block all email though, but you can take a look at the options.

  • Unable to hard code the ports of cisco 3750x series switch

    hello,
    I have tried with hardcode to 1000 7 Full on the ports which are connected to another switch.
    After changing the port to auto from one side of the switch port came up. Is there any solution to make port up when both sides are hard coded to 1000 & full duplex.
    Simple Words:
    Switch 1 --> Switch 2 --> Hard coded to 1000 & Full --> Down.
    Switch 1 --> Switch 2 --> Auto on one end to Switch 1  --> Up.
    Switch model:
    Switch 1 Cisco 3750x (Gi Switch)
    Switch 2 Cisco 3750 (Gi Switch)
    Regards,
    Ezra.

    Yes, it's possible without a straight through cable, enable auto/auto both sides.    Otherwise you'll need a cross-over cable.
    BTW, if your standard is hard coding copper gig ports, for speed and duplex, you might consider bringing your standard up to date.  Copper gig standard went much further in how auto/auto is supposed to work.  By disabling auto/auto, I believe, you're also disabling some error monitoring too.  Generally, all the major players, e.g. Cisco, would recommend auto/auto for copper gig Ethernet.

  • POE device flapping on switch access port

    I have a switch at a remote office.  I have a Cisco 2851 Router and two cisco 3650 POE switches.  I also have three Aruba 105 POE APs. Two are plugged into one switch, and one into another. Yesterday we had a power issue that caused all of the equipment to reboot.  Everything came back up fine except the two Aruba APs that are plugged into a single switch.  The other AP came up fine.  When I do a show power inline, the two APs show that they are getting power from the switch.
    Interface Admin  Oper       Power   Device              Class Max
    Fa0/1     auto   on         15.4    Ieee PD             3     15.4
    Fa0/2     auto   on         15.4    Ieee PD             3     15.4
    When I do a show log, it keeps showing the two interfaces going up and down every couple seconds.

    When I do a show mac-address-table, I can only see the two missing APs for the brief moments that the interface is up.
    What I'm trying to find out, is can this still be a part of the running configuration that never got saved or did the power disruption just cause a  hardware/cabling problem?

    Unfortunately that's not an option here unless I ship mine out and walk a standard non-technical user through the process.  But I will tell you that we moved the AP that was in port one into several other ports on the same switch with no response from the lights, show power inline command, didn't show in the MAC-address-table and then it finally worked on port 31. We moved the AP that was in FA 0/2 into several other ports as well as replaced the cable between the switch and patch panel and the only thing I show is that it registers under the show power inline command, but no light on the port and nothing in the mac-address-table. The AP is located in the ceiling so replacing it will be a last resort.
    Basically I'm wondering if the device is showing power but not mac in the address table, does that demonstrate that the layer 1 is working correctly?

  • Linksys Cisco SRW248G4P 48-port 10/100 + 4-port Gigabit Switch Help

    The switch which is a Linksys Cisco SRW248G4P 48-port 10/100 + 4-port Gigabit Switch, was configured by a contractor which was long ago run off, and the documentation left behind to log into the switch is incorrect. How can we reset this switch so we can configure to the new required settings?
    I have attempted to go in through the web browser gui, and no luck logging in via factory default creditials, cannot log in using any of the common admin creditials, nor can we get in via the documented admin name and pw the contractor left.
    Attempted ot go in through the console, that doesn't work right at all. Takes 15-20 min before I start even seeing user name or password boxes.  Cannot type a single thing into those boxes.  I have set the hyperterminal to com1,  38400, 8, none, 1, hardware.  It kinda lets me see some of the log in screen, but will not let me type into the username whatsoever.
    Logging via web browser I see all the login option but not a single username or pw works. Please if anyone can help, this has been an issue which is now critical.

    Hi, My name is Eric Moyers. I am a Network Support Engineer in the Cisco Small Business Support Center.
    The settings for connection using Hyperterminal through the Console port should be:
    Bits per second: 38400
    Databits: 8
    Pairity: None
    Stop bits: 1
    Flow Control: None
    When you finish configuring the HyperTerminal, the Login screen appears. The first time you open the Console Interface, use the default username admin and leave the password blank and press the Enter key. You can set a password later from the User and Password Settings screen.The Main Menu screen displays six menu choices: System Configuration Menu, Port Status, Port Configuration, PoE Configuration, Help, and Log Out.
    User and Password Settings, IP Configuration, File Management, Restore System Default Settings, Reboot System and Back to Main Menu.
    To restore the Switch back to the factory default settings, select Restore System Default Setting and press Enter. A confirmation message appears asking Are you sure? [Y/N]. Press the Y key to continue or the N key to cancel the action.
    System Configuration Menu options: (Which is where you will need to go) consist of: System Configuration, Management Settings
    After pressing Y, at this point reboot your system and it will be back to Factory Fresh.
    If you have any questions or this doesn't work, please let me know. I am attachng the Admin Guide for you as well.
