Reset Undervoltage Condition
If a power supply experiences a temporary brownout or undervoltage condition,
the checkpower command might indicate an
Alert status for the power supply. The
Alert does not reset upon supply voltage returning
to nominal values. If the checkpower command reports an
Alert, yet supplied voltage is known to be
sufficient, perform this task.
-
Remove the power cord from the suspect power supply.
-
Remove the power supply from the switch chassis.
-
Wait for 1 minute.
-
Install the power supply into the switch chassis.
-
Attach the power cord to the power supply.
Note -
If the checkpower command still displays an
Alert status for the power supply, refer to
Gateway Administration, troubleshooting the
switch, to troubleshoot the power supply.
