Issue with the 1200DC power supply in 8806 blackdiamond

Tamil — Fri, 06 Nov 2015 14:33:00 GMT

Hi Experts ,

We are getting the below error in one of the attached DC power supply in the 8806 chassis

MSM-B: Output current conversion not available for PSU (Part name 2350 rev 5.0) for 48 V sensor in slot 3 due to Part name not recognized. Sensor detection 47.86V, 2.0A

MSM-B: Power usage data unknown for PSU (Part name 2350 rev 5.0 input 57.50 V) in slot 3 due to Input volt not in range

Hi Tamil,

As per the outputs i believe the PSU in the slot-3 is causing the error logs since it is the new one installed as per odometer age.

Do you not see any error message with the PSU-3 removed from the switch?

Can you try with a different PSU and see if the errors still occurs? or the PSU 3 in different switch and see it causes the same error message.

With these information i would suggest to open up a case with GTAC for the same.

you could add these additional outputs as well
"show version"
"show switch"
"show log"
"show log messages nvram"

Regards,
Karthik Mohandoss

Hi Karthik,

Thanks for the quick reply .We tried with multiple power supplies and different slots in the switch , but still issue is there. Anyway we are checking WRT the power source for that power supply.

Tamil

Digging back in my memory but If I recall some of the older power controller's on the 8000 chassis are not fully compatible with the newer psu's .... We ran in to something similar to this 3 or 4 years ago going from a old chassis a/c to d/c conversion.... We ended up replacing the chassis as the controllers were not serviceable (they can be removed but no real part number) Cleared things right up and in the end having a new chassis was the right choice because we now have 40 gig blades in that one and it was and original 8800 chassis that had C cards in it before the upgrade...

We can send replacement PSU Controllers, but you're right, if there's an older 8810 chassis the "8900 Series" cards won't work.

Tamil, can you share the output of

code:

show version

? I can check to see if EtherMAN's hypothesis could apply.

The power supply was working fine previously without any issues , but last 20 days only we are getting the error logs.

Hi Tamil,
The issue with the 8810 Chassis and 8900 modules only affects serial number codes 0533x-xxxxx or earlier. So yours doesn't have this problem.
That doesn't mean there isn't a potential problem with a PSU itself or the PSU Controller.

The only other potential issue I notice in your output above is that your input voltage is >55 VDC. The PSU should be supplied with -48VDC @ 50A.
Over time, voltage outside of tolerance can cause undue stress on components and lead to premature failure. I'm not saying that is the case here, but is a possibility.

In this case, I would suggest reducing supply voltage to 48V and seeing if the problem resolves itself. Beyond that, this would best be solved by GTAC.
