Connecting DC power to the chassis
You can use a DC power source for the Brocade chassis using a DC-to-DC power supply. DC power
must be supplied at 48 V and 30 A.
To perform this task, you need the following items:
• Flathead screwdriver
• Phillips-head screwdriver
• #6 AWG wire (grounding wire)
• #8 AWG wire (input wire)
• Crimping tool
To connect a DC power source, complete the following tasks.
1. Crimp #6 AWG ground wire and connect it to the ground position on the chassis. The ground
position is located on the side or rear of the chassis next to the ground symbol.
