Sun Datacenter InfiniBand Switch 36 Product Notes for Firmware Version 2.2

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.

1. Remove the power cord from the suspect power supply.
2. Remove the power supply from the switch chassis.
3. Wait for 1 minute.
4. Install the power supply into the switch chassis.
5. Attach the power cord to the power supply.

   Note -  If the checkpower command still displays an Alert status for the power supply, refer to the Sun Datacenter InfiniBand Switch 36 Administration Guide for Firmware Version 2.1 for information on troubleshooting the switch and the power supply.
