Powering on the 5U expansion enclosure: 2145-92F
Use the following procedure to provide power to the 2145-92F expansion enclosure as part of the initial
installation process or after a service procedure.
Before you begin
Important:
• To support the 2145-92F expansion enclosure, the SAN Volume Controller system requires software
version 7.8.0 or later. If software version 7.8.0 is not installed on the system, do not connect or power
on the expansion enclosure.
• Before you connect the power cables to the rear of the enclosure, always check that the expansion
enclosure is secured in the rack. If needed, tighten the thumbscrews on the front of the enclosure ( 2 in
Figure 138 on page 127) to ensure that the enclosure drawer does not roll open.
About this task
The 2145-92F expansion enclosure has two power supply units (PSUs) that are accessible from the front
of the enclosure ( 4 in Figure 138 on page 127). As the figure also shows, the PSUs are covered by the 1U
fascia ( 5 ).
