Restore Power After an Emergency

Note: Controllers in a Fibre Channel RAID Storage Server will not acknowledge
Instructions
Use this procedure to restart the drive module after a power failure or emergency
shut down. The following instructions assume that you turned off the power
switches on the drive module during an emergency situation or after a power
outage occurred.
1. After the emergency situation is over or power is restored to the building, check
2. Plug in the power cords and turn on the power switches (Figure 81 on
3. Check the LEDs on the front and back of the drive module.

Checking the Drive Module

This section tells you how to check the status of the drive module LEDs.

Status LEDs

The drive module's LEDs indicate the status of both the drive module and the
individual components within the drive module. The green LEDs indicate a normal
operating status; the amber LEDs indicate a hardware fault. It is important that you
check all the LEDs on the front and back of the drive module when you turn on the
power. Besides checking for faults, you can use LEDs on the front panel to
determine if the drives are responding to I/O transmissions from the host.

Check the Overall Hardware Status

Instructions
Use this procedure to check the operating status of the drive module and its
components.
1. Check the LEDs on the front panel (Figure 82 on page 157).

the drive module for damage.
DO NOT continue with this procedure if you find any evidence of fire, water, or
structural damage. Depending on the current service agreements, you may or
may not need to send the unit back to the factory for repair/replacement. Call
the factory (or appropriate service organization) for assistance. If there is no
visible damage, go to Step 2.
page 154).
After you have checked for damage, plug in the drive module's power cords.
Turn on both power switches. During the power-up process, the drive module
LEDs may turn on and off intermittently. When power-up is complete, the green
LEDs should be on and the amber LEDs should be off.
Check all of the LEDs on the front panel and on all of the FRUs on the back of
the drive module. The green LEDs should be glowing and the amber LEDs
should be off. If one or more Fault LEDs turn on, go to "Drive Module
Troubleshooting Chart" on page 198 for instructions.
