–48 VDC Power Supply LEDs and Connectors for Cisco ASR 1013
This section provides information about the –48 VDC power supplies on the rear of the Cisco ASR 1013
Router. The maximum branch circuit for the–48 VDC power supply module is 60 A and the minimum is 50
A.
The information in this section applies to the ASR1013/06-PWR-DC power supply. The Cisco ASR 1013
Router and the Cisco ASR 1006 Router support this power supply.
Note
The –48 VDC power supply operates within specification from –40.5 VDC to –72 VDC continuously. The
Cisco ASR 1013 Router has two of the same type power supplies in power supply slot 0 and power supply
slot 1. The power supply slot numbers are on the left side of the chassis and the power supplies are located
on the floor of the chassis.
The –48 VDC input connector is a terminal block style that supports a AWG #6 wire. The terminal block is
compliant with safety agencies’ guidelines and electrical requirements of the supply. Use the tie wraps to dress
the input cable wires. There are three tie wrap tabs on the power supply.
The terminal block accepts two-hole lugs, one for the –48 V input and the other for the –48 V RTN. A plastic
cover is fitted over the terminal block to prevent accidental contact.
The studs on the terminal block are similar to the safety ground device on the bottom rear of the Cisco
ASR 1013 Router. For information on the safety ground lug on bottom rear of the chassis, see the xref
“Attaching a Chassis Ground Connection” section.
Note
The unit requires a power switch circuit breaker to serve as the main disconnect for the –48 VDC input to the
power supply. The circuit breaker meets international safety requirements and supports 80VDC and has a
current rating of 50 A. The power supply unit is secured into the system chassis with four captive screws
mounted on the faceplate.
The following figure shows the –48 VDC power supplies at the rear of the Cisco ASR 1013 Router. The Cisco
ASR 1013 Router supports up to four power supplies.
