Chassis power error and time

Question

major,F0408,117295,sys/chassis-1/fault-F0408,power-problem,2012-08-08T13:45:12,Power   state on chassis 1 is redundancy-failed
what does this mean? Both the power cables are connected, and they have status "Operable" in Chassis Power GUI.
Other than that, no faults.
Is it possible to set the time without using NTP? Do I have to set time from NX-OS command-line?

Hi Atle,
I have seen that kind of issues here and there is something you can try in order to correct this problem:
A workaround to clear the I2C faults is to reseat fan trays, PSUs, and IOMs. Here is how to do it:
1.            Reseat the fans from fan 1 to fan 8.
2.            Reseat the PSUs from PSU 1 to PSU 4.
Pull the components out one at a time from 1 to the last, leave it out for at least 3 minutes before reinsert it back, observe the light to make sure all return to green before pulling the next one.
3.            If the above does not work, pull out the IOM that is
flashing amber. Leave it out for 5 minutes and reinsert. Make sure
everything comes up and the lights turn green.
4.            Monitor the system while reseating components by issuing
# show tech-support chassis 1 iom 1 brief
5.            May have to reseat the second IOM if amber lights shifted.
6.            If reseating the IOM does not solve the problem, we may
need to reacknowledge the chassis. This is disruptive to network
connections of the blades. You need a set a downtime to do it.
7.            Repeat these steps on all chassis that are having amber lights.
I strongly recommend you upgrade the firmware to 1.4(3q) and above when
you are able to set a downtime. The errors will need to be clear before
the upgrade. Otherwise the message may remain until you reseat the
components.
This is just a cosmetic issue on the UCS environment.
Hope this helps!
