Each PSU has a power supply connector and power cable, which are accessible
from the back of the enclosure, as shown in Figure 135 on page 142. 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. Also, ensure that each cable is installed along one of the
cable management arms. The cable management arms also support the SAS
cables.
Important: Always secure each power cable with a cable retainer and ensure
that the cable is installed along one of the cable management arms. When
secured, the power and SAS cables stay connected when you slide the
expansion enclosure out of the rack to perform service tasks.
