IE 4000 Controller Error

[Cisco52383]

I get a repeating error in my log file...

Sep 10 15:35:21.860: %ILPOWER-3-CONTROLLER_ERR: Controller error, Controller number 0: power supply removed
Sep 10 15:35:25.865: %ILPOWER-4-ILPOWER_POE_PS_REMOVED: PoE Power Supply loss detected
Sep 10 15:35:28.872: %ILPOWER-4-ILPOWER_POE_PS_RECOVERY: PoE Power Supply Restored
Sep 10 15:35:29.092: %ILPOWER-3-CONTROLLER_ERR: Controller error, Controller number 0: power supply removed

This message repeats forever. I have checked the cables, additionally there are no cables plugged into the PoE ports.

sho env power

POWER SUPPLY A is DC OK
POWER SUPPLY B is DC OK - Alarm disabled

This is a production switch so a reboot will have to wait, but is there anything else I can check that might be causing this issue?

[balaji.bandi]

check by reseating or connecting other source. if not fixed raising TAC case is good option (may be hardware PSU issue ?

)

[Cisco52383]

Thank you for the suggestion. I will work to get the power supplies re-seated. Unfortunately I can't open a TAC case since I don't have a support agreement with Cisco for this particular device.

Take the Maintenance window, try to reseat, and use same power source on working PSU, so you will have idea what is wrong, based on the outcome you can place order or buy failed PSU if required.

I performed a reload on the switch this morning and that cleared up the issue.  Thank you for all your help.

Not for long. 

Look at the IOS version.  It is "E0a" -- That means a version "zero" a re-build. 

So whatever bug was being encountered will, eventually, return.

[Cisco52383]

Thank you for that insight, I will look to get all switches with that version updated.

Hello,

do you have 'power-supply dual' configured on the IE4000 ?

Post the output of:

show alarm settings

to find out what your alarm settings are. You probably have 'alarm facility power-supply disable' configured as well ?

As for the 'alarm facility power-supply disable' I haven't touched that in my config, whatever the default is it still is.

What firmware is the IE running on? 

IF there is nothing connected to this port, try killing the power to the port:  power inline never

[Cisco52383]

Cisco IOS Software, IE4000 Software (IE4000-UNIVERSALK9-M), Version 15.2(6)E0a, RELEASE SOFTWARE (fc1)

I have already set the ports to power inline never.

[Leo Laohoo]

Upgrade the firmware.
