v To support the 2077-92F expansion enclosure, the Storwize V5000 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.
v 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 115) to ensure that the
enclosure drawer does not roll open.
About this task
The 2077-92F expansion enclosure has two power supply units (PSUs) that are
accessible from the front of the enclosure (▌4▐ in Figure 115). As the figure also
shows, the PSUs are covered by the 1U fascia (▌5▐).

Each PSU has a power supply connector and power cable, which are accessible
from the back of the enclosure. Power is provided by plugging a C19-C20 power
cable into each power supply unit and, if necessary, turning on the power source.
The expansion enclosure does not have a power button.
Procedure
1. Connect the C19-C20 power cables to the power connectors on the rear of the
expansion enclosure. The enclosure automatically powers on and begins its
Power On Self-Tests (POST).
2. Secure the power cables in the cable retainer at each power connector on the
rear of the enclosure, as shown in Figure 116 on page 133. Also, ensure that
each cable is installed along one of the cable management arms. The cable
