The power supply has a handle, to assist in insertion and extraction. The module must be supported with one
hand because of its length. The following figure shows the Cisco ASR 1001 Router DC power supply.

Two types of DC connector plugs are supported for use with the DC power supply for the Cisco ASR
1001 Router. In one type of connector plug, the screw holes are raised above the connector plug body. In
the second type, the screw holes are not raised above the connector plug body. xref fig shows the connector
plug in which the screw holes are not raised. The only difference in the method for using these two types
of connector plugs is related to the wire-strip length, which is mentioned later in this section.
Note
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 negative (–) terminal and red is used for RTN on the positive (+) terminal. Make certain the lead
color coding you choose for the DC input power supply matches lead color coding used at the DC power
source.
•
Make certain that the chassis ground is connected on the chassis before you begin installing the DC
power supply. Follow the steps in the xref “Attaching a Chassis Ground Connection” section.
When you install a power supply unit, the ground connection should always be made first and disconnected
last. Statement 1046
