Power Supplies for the Cisco ASR 1002 Router
AC Power System Output Voltage Alarm Range for Cisco ASR 1002 Router
The AC power supply output voltage alarm occurs when the output voltage is below the low end of the
minimum or above the high end of the maximum limits shown in
Table 2-21

Cisco ASR 1002 Router –48 VDC Power Supply
This section provides information about the –48 VDC power supplies on the rear of the Cisco ASR 1002
Router. The recommended branch circuit breaker for the Cisco ASR 1002 Router –48 VDC power supply
is 30 A. Use an AWG #10 maximum wire gauge on the 30 A circuit. The maximum branch circuit for
the –48 VDC power supply module must not exceed 30 A.
The Cisco ASR 1002 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 power supply switch is a standby switch and is not considered
a disconnect.
The –48 VDC input connector is a Euro-style terminal block. The largest size gauge of wire that the front
panel euro-terminal block can accept is AWG #10 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 two tie wrap tabs on the –48 VDC power supply.
The –48 VDC power supply unit is secured into the system chassis with two captive screws mounted on
the faceplate.
