7. Turn on the drive power switch for one of the disk drives. This switch is
shown in Figure 4–1.
8. Verify power application to the disk drive position by noting that the indicator
element in the drive power switch lights. If the indicator element does not
light, verify that the power supply is firmly seated in its connector. If power
still does not come on, see Chapter 5.

drive motor.

the drive motor. When the Ready light comes on, the drive has completed its
internal diagnostics and is ready for operation. If the Fault light comes on,
see Chapter 5 for more information.

light. If the indicators do not light, see the Chapter 5 for more information.
You can turn off write protection by pressing the Write Protect switch a
second time.
