are OK and OVER-CURRENT. In either case, OVER means over the set
threshold of the voltage or current.

/cx/ex/pwrsx show identify
The /cx/ex/pwrsx show identify command applies only to 9750 and 9690SA
controllers. For the 9650SE, simply drop the prepended controller name in the
command and use /ex.
The /cx/ex/pwrsx show identify command shows the identify status of the
specified power supply element. The status can be either on or off. If identify
is on, the LED associated with the power supply blinks. If the enclosure does
not support Power Supply Identify, this command returns N/A.
Example:
//localhost> /c0/e0/pwrs1 show identify
/c0/e0/pwrs1 Identify status = on
/cx/ex/pwrsx set identify=on|off
The /cx/ex/pwrsx set identify command applies only to 9750 and 9690SA
controllers. For the 9650SE, simply drop the prepended controller name in the
command and use /ex.
If the enclosure supports Power Supply Identify, this command causes the
LED associated with the power supply to blink, or turns off identification of
the LED for this power supply.
Example:
//localhost> /c0/e0/pwrs1 set identify=on
