Control enclosure:
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 6 on page 37 to verify the state of the light
emitting diodes (LEDs) on on the system. Verify that no faults are detected. See
the
Storwize V7000 Unified Problem Determination Guide PDF on the CD if
problems are encountered.
Both Figure 38 and Figure 39 show the location of the LEDs on the power supply
units, located at the front of the expansion enclosure. Figure 40 on page 37 shows
the location of the LEDs on the power supply units, located at the rear of the
expansion enclosure. The LEDs are located at position
1
.
