Cisco ASR 1001 Router Power Supply Installation
Installing DC Input Power on the 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. See
Figure 12-21
.
The power supply has a handle, to assist in insertion and extraction. The module must be supported with
one hand because of its length.

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” section on
page 12-27
.
Warning
When you install a power supply unit, the ground connection should always be made first and
disconnected last.
