Difficulty getting PoE started and configured
Difficulty getting PoE started and configured
Hi all, I need a little bit of help to get our 7750 to enable PoE to our new Cisco 7960, and 7971 handsets.
We just purchased and added to our switch a 3c16890 48 port 10/100/1000 PoE Module card, as well as the 3C16883 External PoE Power rack. They are both installed, connected and seem to be functioning correctly as per install guides.
I have a 3C16890 ver. C card in slot 1, and the new 16890 ver. D in slot 4
I updated switch software to 3.03.00rp1 and boot rom to 532
Slot Name Software Ver Hardware Ver BootROM Ver Uptime
SLOT0 Main Board 3.03.00rp01 VER.C 532 0 Days 15 hours 37 minutes 40 seconds
SLOT1 Board1 3.03.00rp01 VER.C 532 0 Days 15 hours 34 minutes 56 seconds
SLOT2 Board2 3.03.00rp01 VER.D 532 0 Days 15 hours 35 minutes 1 seconds
SLOT3 Board3 3.03.00rp01 VER.D 532 0 Days 15 hours 33 minutes 26 seconds
SLOT4 Board4 3.03.00rp01 VER.D 532 0 Days 15 hours 33 minutes 52 seconds
SLOT5
Using Device Manager, I am unable to configure any PoE ports, the software reports "the selected ports do not support PoE" I have tried on both the new and old 3c16890 cards.
I have also tried to set the ports using the telnet CLI interface with the commands:
system-view
poe enable slot 4
and the port:
system-view
interface GigabitEthernet4/0/1
poe enable
Is there something I am missing? It seems like it should all work at this point, but I am not having any luck, and cannot find any good documentation or guides on how this is really supposed to be configured.
Thanks for your help. I'll respond with any additional info that can help asap, as I am stuck.
thanks Monte.

Re: Difficulty getting PoE started and configured
I am now up and running with a little help from 3 com tech support. Thanks Fabio! I really can't thank you enough.
My system was setup and running correctly, with all the right components, firmware, bootrom and software versions.
The "magic command" to make my PoE devices all work, (cisco phones, and panasonic network camera's) was to enable legacy mode.
system-view!
poe legacy enable slot 4!
and everything powered up.
You can find more details on this command in chapter 63, page 855 of the command reference guide.
My advice, is to try your PoE devices the standard way, but to try the Legacy mode if it's not working after that point.
Best regards,
Monte
