Product Notes for Firmware Version 2.0
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 the following task.
Note - If the checkpower command still displays an Alert status for the power supply, refer to Switch Administration Guide, troubleshooting the switch, to troubleshoot the power supply.
For optimum thermal management, ensure that the three fans shipped with your switch are installed at the central fan slots, Fan 1, Fan 2, and Fan 3. Installing any one of the three fans in fan slots Fan 0 or Fan 4 is not supported.
