Assemble one cable for each DC power supply in your server.
Before you begin the installation procedure, verify that the required conditions described in the following table have been satisfied.
Caution - Do not proceed with these instructions until you have turned off the power from the DC power source through the circuit breakers.
For each cable, you need the items shown in. These items are provided in the shipping kit that came with your server.
Figure 37 DC Connection Parts
-48V or -60V (negative terminal)
-48V or -60V Return (positive terminal)
Note - Depending on the DC power source, the -48V or -60V (negative terminal) might be marked with a minus (-) symbol. The -48V or -60V Return (positive terminal) might be marked with a positive (+) symbol.
Do not strip more than 5/16 in. (8 mm) from each wire. Doing so leaves uninsulated wire exposed from the DC connector after the assembly is complete.
