Installing DC Power Supply into Cisco ASR 1001 Router
The Cisco ASR 1001 Router DC input connector is compatible with a pluggable Euro-style plug. The
input connector and plug must be UL recognized under UL 486 for field wiring. The connection polarity
shall be from left to right: negative (–), positive (+), and ground.
The power supply has a handle, to assist in insertion and extraction. The module must be supported with
one hand because of its length.

In the second type, the screw holes are not raised above the connector plug body.
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

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
