SG 200-08P

Do you know what the applications of the following may be?
We are using a Cisco smart switch (model # SG 200-08P) and pinging the WK2 to check for Ethernet communication. When “DHCP auto configuration” is enabled the Cisco switch generates a consistant TFTP read request:
Opcode: Read Request (1)
Source File: fp-net.cfg
Type: octet
This subsequently locks up the WK2 for a few seconds at a time and disables Ethernet communication. If the “DHCP auto configuration” is disabled on the Cisco switch, then there are no problems.
Test Results:
DHCP Auto Config Enabled:
6ft/Direct PCB – Fail
100m/Direct PCB –Fail
6ft/ Jumper –Fail
100m/ Jumper –Fail
DHCP Auto Config Disabled:
6ft/Direct PCB – Pass
100m/Direct PCB –Pass
6ft/ Jumper –Pass
100m/ Jumper –Pass

Hi Jens-Peter,
I would try disabling smartports and green ethernet on the SG200 switches. Then you will need to hardcode each of the ports to have the necessary settings. Often times when a reboot is required to restore functionality smartports is the cause.
As for the 6921 phones, you need to be sure to have auto voice vlan enabled. Otherwise the phones will not be able to pick up the correct VLAN via CDP. Let me know, if you have any questions.

PoE does no work for my SG 200-08P ?

Hi,
I've bought two SG 200-08P which have their 1-4 ports who can delivered PoE.
Whatever the PoE equipments I plug into those ports, it doesn't work.
If I plug a non PoE equipment in the 1-8 ports it's working fine.
I can log into the web interface of the switch, and when I go to "Port Management > PoE > Properties", I can see the following screen:
I don't know how switch the "Power" option to "On"...
I have the exactly same issue with a second and new SG 200-08P.
I've changed the firmware and I am now in the 1.0.6.2 version but I have the problem with the original version.
I also try to reset the switch several times, but it doesn't change anything.
Is anyone has a idea to what can I do or test ?
Thanks.

Hi Tom,
For now, I only try to connect differents Siemens IP phones (1 or 2 or 3 PoE classes) : OpenStage 20,
OpenStage 40 and OpenStage 60.
Those Siemens phones are working fine with other PoE switches like linksys, HP, catalyst, 300 series, Netgear ...
I've just noticed something interesting, in the "Status and Statistics > View Log > RAM Memory" menu :
When I clear the logs, only my computer is connected on port 8...
I'll try to find other PoE devices, to test with.
Regards.

SG 200-08P Secure lockdown question/s

I have an SG 200-08P. I need to restrict access to the web interface for security. Unfortunately I have found this nearly impossible.
- Is there any way to restrict access to HTTPS? Seems simple but I haven't found a method of doing so. IIRC this is required for compliance with some security standards.
- How can I set the switch to only allow management from a single port (it seems like this is an option but I haven't figured out how). Every time I try to set up a VLAN for administration the switch ends up locking out all connections or something similar and I have to reset it.
- As far as I can tell the 'cisco' user can not be deleted, disabled, or removed from administration under any circumstances. Is that really correct? Seems like a horrific security hole to me.
Thanks in advance for your time.

I finally got things configured so only one phisical port can be used for administration.
I am still not happy with Cisco for disallowing the re-naming of the default user and especially for leaving HTTP open no matter what.

SG 200-08P - connecting PCs and Phones

Hello,
we have a serious problem over here with some new SG 200-08P switches firmware: 1.0.6.2
They are setup behind 2 SG-200 50 layer 2 switches - actual firmware 1.3.2.02.
We have 4 VLANs: 1 for DATA and 2 for PHONE, 10 fpr MGMNT and 20 for GUESTS - on the 08-P only VLAN 1+2 is needed. CDR protocoll is active.
Ports 1-7 on the 08-P is setup as "Trunk, 1U, 2T", parameter: Auto Negotiation ON. We tried FlowControl ON and OF - makes no difference. Port 8 is setup as "Trunk, 1U, 2T, 10T" to the floor switch. The connecting port on the floor switch SG-200 50-switch ist setup as "Trunk, 1U, 2T, 10T".
One of the problem switches: on port 1-4 of the 08-P there are connected 4 Cisco 6921 phones . On Port 5-7 there are connected 1 HP Z400 and 2 Elite 7200 PCs. One of the 6921 phones is switching to a DELL Latitude 6420 laptop.
So it happens every morning, that the first staring PC ist working fine, then the switch has to be switched off and on to get the next PCs connected to the network. The switching 6921 phone does not connect at all. But after some more switching off/on it works.
We thried another 08-P hardware with the same config, we tried an older firmware level ... we setup the PoE-phone ports as GENERAL 1U, 2T. We gave external power to the phones so that PoE is not overloaded ... nothing helps. Only some switching off/on helps and the PC gets its IP address from DHCP and the phones all come up an find the CU 6000.
Is there someone outside who may give a helping hand on this?
Thanks so far...

SG-200-08P POE

Hi. I have a configuration whereby I use a SG-200-08P to power a SG-200-08 (no PSU connected) which in turn is connected to another SG-200-08 that is powered via PSU. It seemed to work but recently I've been getting connectivity issues. The Ethernet cable from the non PSU powered SG-200-08 to the PSU powered SG-200-08 is 100m. Are there any ways to configure these switches in order to resolve the connectiviy issues? Thanks.

Tom, many thanks for the response. I definitely think it's a power issue as the connection to my laptop keeps trying to connect/identify for a few seconds, then stops, then trys again/again and 100m is quite a long run from a switch that's powered by POE. Configuration is as follows:-
Router -->>--SG-200-08P -->>-- 100m -->>-- SG-200-08 (no PSU) -->>-- 100m -->>-- SG-200-08 (with PSU) -->>-- Laptop
My first thoughts were to attach the PSU to the SG-200-08 in the middle that's running off POE at present. Although because a power source isn't easily available there I was hoping I could perhaps divert more power to the port in the SG-200-08P that's powering the SG-200-08. Thanks. Guy

SG 200-08p Wont upgrade firmware

I have a fleet of the SG-200-08P switches which are way behind on firmware. I went to upgrade them to the newest firmware available:
     "sx200_fw_1.3.7.18.ros"
After about a 5-7 minute wait, the web interface returned the message (tired multiple times):
     "Firmware Image download through HTTP failed. Wrong File Type."
I reset the router, same results. I went and installed the second most recent verson, "SG200-08x_FW_1.0.7.4.stk", which installed without any issues. Then tried the "sx200_fw_1.3.7.18.ros" file and again with the same result:
     "Firmware Image download through HTTP failed. Wrong File Type."
I then did a factory reset and tried again, same results. It seems that none of my routers want to use the .ros files, it preferes the .stk files. What am I doing wrong?
I'm accessing the upgrade feature via "Main Menu -> Administration -> Upgrade/Backup firmware" and have it set to:
X - via Http
X - Upgrade
X - Firmware image
Please HELP!!!

Thanks for the info. I was working off another post where someone laid claim to installing the 1.3.x firmware on their sg200 to enable SNMP protocols for Spiceworks Management software.
Does this mean there is no SNMP options for the SG200-08P switches?

SG 200-08P config and firmware

Hi,
we just got 10 new devices with the actual fw 1.0.6.2.
Two problems were coming up ...
First: user and password ... The other SG 200 switches allow password with special characters like !? ... the SG 200-08 does not! That is not very helpful.
And we would like to have this fixed.
Second: After configuation of VLANs along with CDP an Cisco Phones we always had to restart the device to be sure the configuation change was applied. Otherwiese we were hunting problems that did not really exist. May be this could be fixed in a new version of the firmware, too.
Thanks ;-)

Broken SG 200-08p switch?? Blinking LED

I turned unplugged it and plugged it back in. Now its blinking green power LED. Is it dead?

By default the switch obtains a DHCP address. If you do not save the running config to the start up config then reboot the switch, the LED will blink green and the switch will get a DHCP address from your network.

WAP4410N - Will the PWRINJ4 power injector be compatible

Good day,
We have purchased a few WAP4410N access points at some of our small remote offices. The switches in the offices is not PoE capable, therefore we require power injectors. I have a PWRINJ3 injector in my posession, so have tested it with the AP's, but it does not seem to be compatible.
Before I purchase power injectors, I would like to know whether the PWRINJ4 will be compatible, if not, which power injector does Cisco recommend for the WAP4410N.
Kind Regards
Adrian

Hi, My name is Eric Moyers. I am a Network Support Engineer in the Cisco Small Business Support Center. Thank you for using the Cisco Community Post Forums.
We get this question a lot with our wireless AP's. Currently there is not an Injector that we recommend with our wireless AP's. Your best bet is to purchase a small unmanaged PoE switch for all of your AP's. I would suggest something like a SG-200-08P.
http://www.cisco.com/en/US/products/ps11229/prod_models_comparison.html
Cisco currently has an injector in works for our small business devices, but the timeframe for availability is unknown at this time.
There are some 3rd party infectoers on the market(including Cisco Enterprise injectors that could possibly work, however since we do not support them and they have not been certified for use with our small business devices we can not recommend or support them. (even though some customers have been lucky enough to get them to work)
Hope this helps, please let me know if I can answer any other questions.

SF302-08P layer 3 mode

Hi,
i'm trying to configure SF302-08P in layer 3 mode.
ports 1 to 8 have ip phones and desktops, port GE1 in connected to a router (not cisco) that links to the internet.
i created vlan 100 and assigned to ports 1 to 8 (untagged)
i created vlan 200 and assigned to port ge1 (untagged)
activated dhcp server , created pool with 192.168.26.0/24 gw 192.168.26.1
                       |router A| (192.168.16.0/24 gw 192.168.16.1)
                           |
                           |
                           | GE1 (192.168.16.14)
                       | SF302-08P |
                                 |
                                 |
SPA504G+DESKTOP |    SPA504G+DESKTOP
        192.168.26.2                      192.168.26.4
         192.168.26.3                      192.168.26.5
the problem that i'm facing is that SPA504G and desktops access the internet with their inter address 192.168.26.0/24 and not 192.168.16.14.
is there a way to achieve what i'm looking ? how does routing work in this case ? shouldn't there be some kind of NAT ?
thank you

Hello Luis,
Is there a particular reason that the switch needs to be in Layer 3 Mode?
I think your scenario would work better if you configure NAT on your router and let the router act as the DHCP server. Then, the switch could be in Layer 2 Mode.

Legacy PoE on SG200-08P?

Hi,
I saw the annoucement stating that "200 and 300 Switches now supports Cisco Pre-standard POE" available here:
https://supportforums.cisco.com/docs/DOC-18337
However, I cannot find the 1.1.1.8 firmware for the SG200-08P in the download center (latest is 1.0.1.0).
Does this mean this doesn't apply to the SG200-08P?
If it doesn't apply, any other switches with 16 or less all gigabit ports which support legacy PoE?
Thanks.

Hi
I noticed in CCA release notes two versions of the 200 series switches were not supported by Cisco Configuration Assistant . To me this means that these two switches are not using version 1.1.1.8
Have a chat to the good folk of SBSC, they can track down if the reason for the current software not being available for your switch.
http://www.cisco.com/en/US/support/tsd_cisco_small_business_support_center_contacts.html
Not that it's any consolation, but I also confirmed your finding.

ITunes wont open Error -200

yep
well there i was opening iTunes
and BLAMMO !
ITunes wont open
error -200
what am i doing wrong now
also coincedently my sound output aint working

Also, I have not moved any files since updating. Still won't do anything.

IPhone limited to 130 apps at a time! 6,200 apps available in app store

The i phone is limited to nine app screen i notice this when i try to move on to a tenth screen and it would not let me and also when you download a app after all 9 screen are full the app dose not show up but the app store says it is installed apple needs to expand the amount of screen allowed. you then end up having to delete 2 apps download 1 app in able to make the invisible app appear you have to try this one out for your self so you get a better idea of what i mean so it looks like we are limited to 144 apps per iPhone subtract 14 apps that come default on the screen not including the 4 that are on the bar below you are left with 130 apps that can be downloaded and use at a time per i phone that ***** there are over 6,200 apps available in the app store as i type this to you and apple is limiting me to only carry 130 at a time there is somthing worng with this and i think somthing should be done!

No acutally what that means is most people like myself have to install 30 apps just to get the iphone to do half the things it should have done out of the box. Sure some are wants but most are "need" in order for it to do the things my old palm treo 600 could do, and still there's not copy and past and no video. On top of that they have a stupid 130 limit. I'd love to hear why that is.

I restored my ipod from a previous backup and I lost all of my photos but it still displays that I have 200 whatever photos, I just cant veiw them. Please help me.

I restored my ipod from a previous backup and lost my photos. The funny thing is, the photo app says that I still have 200 something photos I just can't view them. My iPod says: Unlock your iPod to view your photos.-What does this mean? How can I fix it?

After you restore from backup, you MUST sync to restore your iTunes content. No iTunes content is included in the iPhone backup. Your apps should be in your iTunes library, just sync them back to your phone. If for some reason your apps are not in your library, you can re-download them for free:
