Features On The Front Of The 2077-92F Expansion Enclosure; Display Panel Leds; Power Supply Unit Leds - IBM Storwize V5000 Gen2 Quick Installation Manual

• 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.
• 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 (
Figure 115 on page 109) 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 on page 109). 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 110. Also, ensure that each cable is installed along one of the cable
management arms. The cable management arms also support the SAS cables.
