3850 - %NGWC_PLATFORM_FEP-6-FRU_PS_OIR

[nideville]

Hi,

We have just installed 2 new 3850 switch in a stack.

Everything went fine and now I have some error logs in loop.

Jul 19 16:30:41.388 CE: %NGWC_PLATFORM_FEP-6-FRU_PS_OIR: Switch 1: FRU power supply A removed

Jul 19 16:30:41.743 CE: %NGWC_PLATFORM_FEP-6-FRU_PS_OIR: Switch 1: FRU power supply A inserted

Jul 19 16:30:41.744 CE: %NGWC_PLATFORM_FEP-6-FRU_PS_OIR: Switch 1: FRU power supply A powered on

SWR-3850-RO-SS-12#

Jul 19 16:30:46.966 CE: %NGWC_PLATFORM_FEP-6-FRU_PS_OIR: Switch 1: FRU power supply B removed

Jul 19 16:30:47.351 CE: %NGWC_PLATFORM_FEP-6-FRU_PS_OIR: Switch 1: FRU power supply B inserted

Jul 19 16:30:47.351 CE: %NGWC_PLATFORM_FEP-6-FRU_PS_OIR: Switch 1: FRU power supply B powered on

I understand this logs but I don't know am I receiving it.

I've tried to unplug and plug again the 2 power supply but I still get this messages.

I also tried to invert a power supply from switch 1 to switch 2 and I still get this message for Power supply A and B of switch 1

This meams the power supply seems to work.

So it may be a problem with switch 1

Any idea ?

Best regards,

Nicolas

Hi,

If I repeat this command several times I can see that when the error message come I have this

SWR-3850-RO-SS-12#sh environment power all

SW  PID                 Serial#     Status           Sys Pwr  PoE Pwr  Watts

--  ------------------  ----------  ---------------  -------  -------  -----

1A  PWR-C1-350WAC       DCB1650H090  OK              Good     Good     350

1B  Unknown             Unknown      OK              Good     Good     235

2B  PWR-C1-715WAC       LIT17050CEY  OK              Good     Good     715

And just after the error message :

SWR-3850-RO-SS-12#sh environment power all

Was looking at a similar issue and found 

CSCug23120
The show environment power all command randomly displays a power supply failure message and displays the wattage is displayed incorrectly as 235 W.

There is no workaround.

Resolved in IOS XE Release 3.2.2SE

Hey guys,

Does anyone know where to get the all the system messages error guide that a 3850 can generate?  They have the guides for all the other platforms, but I am not able to find them for the 3850.

Similar to the %NGWC_PLATFORM_FEP-6-FRU_PS_OIR above.  It's just a list of all the messages that get logged on a switch like Power supply fail, or bpdu guard, or ospf errors...etc..

Thank you
