CBC alarms from 0/FT0/SP

Hello, community

 

I see these strange (ungooglable) error logs on ASR-9010:

Do you guys know what is wrong with my fans? Thanks a lot for your time.

hi Arseniy,

these messages indicate a potential contact issue between the fan and the backplane. Can you try to reseat the fan?

Aleksandar

 

Sure, i'll do that and will post back with the result. Thanks.

It can also be that the cbc revision between RP and fantray is out of rev, you could check the

admin show hw-module fpd all loc all to see if there are CBC's to be updated.

it is the i2c bus, which can be reset after the update so no reload is necessary after this rev change.

 

cheers

Thanks, Alexander

The output of the command you mention above shows that the only FPD that need an upgrade is

I did some more research on this.

the FanTray can signal this via the cbc in its alarm register. it is bit 0 that signals that.

the cbc for the LC needs to be updated. far from left field it could be that the LC is sending a message over I2C that gets interpreted as from the FP possibly and results in that bit0 being set printing this alarm.

Considering that it flips constantly and of all the known cases it was resolved with a reboot or reseat, so I think at this point Aleks' suggestion is the only reasonalbe things left to try :).

But please do update the CBC also for all lc's/devices that are in your system.

cheers!

@xthuijs should I reseat the fan tray?

yes that is good first try, also check the cbc version and update it if needed

cheers!
