Power Supplies in chassis 8
PS Operational Status
-----+-------------------
PS-1 UP
PS-2 NOT PRESENT
Make sure that all the known good power supplies are operational.
3 Verify the CPU utilization.
OmniSwitch 6624/6648 and 7700/7800/8800
The CPU utilization of CMM can be viewed by using the command:
-> show health
* - current value exceeds threshold
Device Min 1 Hr 1 Hr
Resources Limit Curr Avg Avg Max
----------------+-------+-----+------+-----+-----+-------
Receive 80 00 00 00 0
Transmit/Receive 80 00 00 00 00
Memory 80 43 43 43 43
Cpu 80 02 06 05 07
Temperature Cmm 50 38 37 37 37
Temperature Cmm Cpu 50 32 32 31 32
The above command shows the receive, transmit/receive, memory, CPU, temperature CMM and tempera-
ture CMM CPU statistics for current, 1 minimum average, 1 hour average and 1 hour maximum. All the
values should be within the threshold. Anything above the threshold depicts that some abnormal behavior.
Normally 1 hour average maximum might be high if the switch was booted up in the last hour but it should
be fairly steady during normal operation.
If none of the above are above the threshold then the next step is to try to isolate the problem to a particu-
lar NI. Due to the distributed architecture every NI has it own CPU to perform some operations locally. It
is possible that a particular NI might be at high CPU utilization at a time when other NI as well as the CPU
are within the thresholds.
If none of the above are above the threshold then the next step is to try to isolate the problem to a particu-
lar NI (or a switch within an OmniSwitch 6624/6648 stack) with the show health slot_number CLI
command:
-> show health 5
* - current value exceeds threshold
Slot 05 1 Min 1 Hr 1 Hr

Transmit/Receive 80 01 01 01 01
Memory 80 39 39 39 39
Cpu 80 21 22 21 24
The principle for the health of an NI is the same as for CMM.
