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 enclosures if they are not already on. 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 49 on page 102 to verify the state of the light
emitting diodes (LEDs) on the system. Verify that no faults are detected. See the
Storwize V7000 Unified Problem Determination Guide book or PDF on the CD,
Information Center, or refer to the Troubleshooting section of the Storwize
V7000 Unified Information center if problems are encountered.
