2811 Voice Bundle PoE issue

I have a 2811 chassis to be used as a demo/learning platform.

- The Inline power supply (PWR-2811-AC-IP) is installed and 48 volts confirmed.

- HWIC-4ESW-POE is installed

  - HWIC-ESW is recognized

  - IPLM-4 is recognized

- IOS Version:     12.4-24 T2

** 79xx phones do not power up **

** In fact, none of the power commands are available. **

Any help would be appreciated.

Thanks,

Bob Ehlenfield

Re: 2811 Voice Bundle PoE issue

Did you purchase the upgrade for the power supply.  In order for ESW card to provide power
you need to have the following internal power supply
installed: PWR-2811-AC-IP

The documentation states For Cisco 2800 and 3800 the internal router power supply should
be swapped out for a new power supply with Power over Ethernet capabilities if Power over
Ethernet is required (examples of PoE enabled power supplies include PWR-2811-AC-IP=,
PWR-2821-51-AC-IP=, PWR-3825-AC-IP=, and PWR-3845-AC-IP=).

vvasisth,

Yes, the correct power supply is installed and, based on the "sho env" results, seems to be functioning properly.

Re: 2811 Voice Bundle PoE issue - UPDATE

I have ordered a new IPLM-4 Power daughter card for the HWIC-4ESW-POE.

Hopefully, that will solve the issue.

I've seen, in the past, modules that were detected but just did not function properly...

Any other insight would be greatly appreciated.

Bob.

Re: 2811 Voice Bundle PoE issue - UPDATE

everything looks fine to me. There are lot of bugs as well for this platform, if you are not able to find a bug then a hardware replacement is the only option left.

The replacement daughter board did the job
