4506 with PWR-C45-4200ACV and WS-X4248-RJ45V POE Mod

Hi Guys,

I've got this issue later wherein my Catalyst 4506 SW (with the modules and power supplies below) had ports in module 2 that do not provide power to the connected phones. There are ports in module 2 that provide power to phones, I think only 26 ports are not working at the moment. Tried to adjust the power inline consumption/static commands but still those ports failed to supply power to the connected phones.

Mod 1 - WS-X4013+

Mod 2 to 6 - WS-X4248-RJ45V

PS1 PWR-C45-4200ACV AC 4200W good

PS2 PWR-C45-4200ACV AC 4200W good

I also see these messages on the switch logs.

Feb 11 10:02:40.012 UTC: %C4K_CHASSIS-5-POEHEALTHCHECKFAILED: Poe Health Check failed on slot 2 (count = 96)

Feb 12 10:02:37.989 UTC: %C4K_CHASSIS-5-POEHEALTHCHECKFAILED: Poe Health Check failed on slot 2 (count = 100)

Does the 4506 has a limitation on the maximum number of PoE ports that it can power up given my modules and power supply capacity mentioned above?

What is the output of sh power?

Thanks for the replies Guys, this has been resolved after reseating the module.

Explanation:
%C4K_CHASSIS-5-POEHEALTHCHECKFAILED: Poe Health Check failed on slot [dec] (count = [dec])

PoE health check has failed on a module. The PoE service provided by the module may be
unavailable.

Recommended Action: If the message shows up rarely and coincides with external events such
as input power supplies being changed, this message can be safely ignored. If the message
shows up continuously, please contact your Cisco representative for a replacement of the
module.

You can reseat the module, check whether it can recover, if not , I think you need try to replace the module.

Thanks,

Jack
