power failure redundancy, plug the power cords for the individual power
supply units for each enclosure into separate power distribution units, if
possible.
Powering on the system
You can use this procedure to power on an expansion enclosure and determine the
status of the system.
About this task
Attention: Do not operate the system when the drive assemblies are missing.
Drive assemblies that are missing disrupt the airflow; the drives do not receive
sufficient cooling. You must insert blank carriers into unused drive bays.
Powering on an expansion enclosure:
1. Power on the newly installed enclosures. Use the power switch on each of the
two power supply units in the back of the expansion enclosure.
2. Use the information in Table 5 on page 16 to verify the state of the light
emitting diodes (LEDs) on the system. Verify that no faults are detected. Refer
to your system Information Center's Troubleshooting section.
Figure 10 on page 16 shows the location of the LEDs on the power supply units in
the rear of the expansion enclosure.
