9407 POWER ISSUE - Insufficient POWER error

syed ethesham ul Hussain · ‎05-22-2023

Greetings,

I have 9407 core switch with 4 modules and 2 sup. We removed 1 old SUP and installed 2 new SUP, after we power up it gives below message. I have tried starting the core with only 1 module as well, but still it gives the same error.

Kindly advice.

- Could be a bogus message similar too https://bst.cloudapps.cisco.com/bugsearch/bug/CSCvq55973 , use latest advisory software version on the 9407 (if applicable) , check if that can help ,

The chassis needs, a minimum, of two power supplies.

Hi Syed,

This maybe a software bug, as we can't see the numbers in the output. If all working correctly, you should see something like below output. So, you may want to open a ticket with Cisco TAC on this and have them take a look.

Hi

They are in err-disable:

PS1 UNKNOWN-PFU AC n.a. err-disable n.a. n.a. n.a. n.a.
PS2 UNKNOWN-PFU AC n.a. err-disable n.a. n.a. n.a. n.a.

Try to remove them and plug again during maintenance window.

>>> I have 9407 core switch with 4 modules and 2 sup. We removed 1 old SUP and installed 2 new SUP, <<<
do you mean you have 3 SUP installed ? that is not correct.
