4.Check the drive LEDs.

a.When a drive is ready for use, the green activity LED and the amber fault LED are off.

b.If the amber fault LED is on, remove the drive from the unit and wait 10 seconds; then, reinstall the drive.

ServeRAID information

In some cases, the ServeRAID controller will automatically reset the drive to the Hot Spare or Rebuild state. If the drive state change does not occur automatically (amber LED stays lit), refer to your ServeRAID documentation for information about manually changing the state of the drive from the current state to another state, such as Hot Spare or Ready. The amber LED should turn off within 10 seconds after the drive-state change.

Working with hot-swap power

Before you begin

Read the safety and handling guidelines provided in “Safety information” on page 41 and "Handling electrostatic discharge-sensitive devices."

The power supplies are customer replaceable units (CRUs) and do not require preventive maintenance.

The power supplies must always be installed in the proper place to maintain proper expansion unit cooling.

Use only the supported power supplies for your specific expansion unit.

Removing a hot-swap power supply/fan unit

Complete the following steps to remove a hot-swap power supply:

1.Turn off the power supply.

2.Unplug the power supply cord from the electrical outlet.

3.Disconnect the power cord from the power supply.

4.Loosen the power supply thumbscrews Þ Ý.

5.Grasp the handles Þ Ý on each side of the power supply, and pull the unit out of the expansion unit.
