Re-assigning IDs to AC power supplies

This feature applies only to PSE9000 AC power supplies.
Power supplies need IDs for easy identification. For PSE9000-A and PSE9000-D AC power supplies, the
system automatically uses the numbers of the slots that hold the power supplies as the power supplies' IDs,
as shown in
assigns IDs at startup. These randomly assigned IDs have no relationship with the power supplies' slot
numbers. You can re-assign IDs to PSE9000 AC power supplies after you install the device. For easy
identification, HP recommends you use the slot numbers as the power supplies' IDs.

To help you correlate the current IDs of AC power supplies with their slot numbers, the switch provides the
power-supply led-blink command. After you execute this command for a power supply, the operation
LED of the power supply blinks to show you its location. If you execute this command without specifying
a power supply ID, all power supplies blink one by one in ascending order of IDs.

To view the models and IDs of power supplies, use the display power-supply command.

change, the IDs of the power supplies remain the same after the reboot.
• If some power supplies have been re-located or some power supplies have been added since the
last ID change, the switch randomly re-assigns IDs to the power supplies after the reboot.
