Connecting Power for DC Systems

A cable is provided with the main and booster cooling assemblies for delivering power from the shelf to the fan cooling assembly. The cable provides for redundancy, and the cooling unit can be powered from two independent shelves.

1.Connect the cable to the connector on rear of the shelf located between the power entry modules (P1 for primary and P3 for redundant). When fully inserted, the cable will latch into place preventing accidental removal. To unlatch the connector, use a small screwdriver to slide the catch lever (located inside the slot on the connector) to the right.

2.Connect the other end of the cable to the receptacle on the rear of the fan cooling assembly, P2. If the redundant portion of the cable is not used, it should be dressed to the side using a cable bundle or a cable management tray.

The cooling assembly cabling for single and multishelf racks is shown in Figure 7-11and Figure 7-12.
