Procedure
To power on the 2U SAS expansion enclosures, complete the following steps.
1. Use the supplied power cords to connect both power supply units of the rst expansion enclosure to
their power sources.
If the power sources have circuit breakers or switches, ensure that they are turned on. The expansion
enclosure does not have power switches. Repeat this step for each expansion enclosure in the system.
Note: Each enclosure has two power supply units. To provide power failure redundancy, connect the
two power cords to separate power circuits.
2. From the rear of the rack, check the LEDs on each expansion enclosure (see Figure 143 on page 129).

The canister is ready with no critical errors when Power is illuminated, Status is on, and Fault is off.
3. Wait for all expansion canisters to nish powering on before you proceed with the system installation
process.
Powering on the optional 2076-92F expansion enclosures
Use the following procedure to provide power to the 2076-92F expansion enclosure as part of the initial
installation process or after a service procedure.
Before you begin
Important:
• To support the 2076-92F expansion enclosure, a Storwize V7000 Gen2 or Storwize V7000 Gen2+
system requires software version 7.8.0. If software version 7.8.0 is not installed on the system, do not
connect or power on the expansion enclosure.
The Storwize V7000 2076-724 control enclosure (Gen3) requires software version 8.2.0 at the latest
available x level or later. If software version 8.2.0.x 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 144 on page 130) to ensure that the enclosure drawer does not roll open.
About this task
The 2076-92F expansion enclosure has two power supply units (PSUs) that are accessible from the front
of the enclosure ( 4 in Figure 144 on page 130). As the gure also shows, the PSUs are covered by the 1U
fascia ( 5 ).
