Figure 41. Features on the front of the 5U92 disk enclosure
1 Display panel LEDs
2 Rack retention thumb screws
3 Power supply unit LEDs
4 Power supply units (PSUs)
5 PSU fascia (1U)
6 Front fascia (4U)
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 disk 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 42 on page 43. Also, ensure that each cable is installed along one of the cable
management arms. The cable management arms also support the SAS cables.
Figure 42. Secure power 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 disk enclosure out of the rack to perform service tasks.
