This section describes how to install the DC power supply ground leads and input power leads to the Cisco
ASR 1001 Router DC input power supply. Before you begin, read these important notices:
• The color coding of the DC input power supply leads depends on the color coding of the DC power
source at your site. Typically, green or green/yellow is used for ground (GND), black is used for
– 48 V
on the negative (
–
) terminal, and red is used for RTN on the positive (+) terminal. Ensure that the lead
color coding you choose for the DC input power supply matches the lead color coding used at the DC
power source.
• Ensure that the chassis ground is connected on the chassis before you begin installing the DC power
supply. Follow the steps provided in the
Attaching a Chassis Ground Connection, on page 438 .
When you install a power supply unit, the ground connection should always be made first and disconnected
last. Statement 1046
