AC Power System Output Voltage Alarm Range for Cisco ASR 1002
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 inTabl e 2-19.
Cisco ASR 1002 Router DC Power Supply
This section provides information about the DC power supplies on the rear of the Cisco ASR 1002
Router. The recommended branch circuit breaker for the Cisco ASR 1002 Router DC power supply is
30Amp. Use an AWG #10 maximum wire gauge on the 30Amp circuit. The maximum branch circuit for
the DC power supply module must not exceed 30Amp.
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 DC input connector is a euro-style terminal block. The largest size gauge of wir e that the front panel
euro-terminal block can accept is AWG #10 wire. The terminal block is compliant to all safety agencies
and electrical requirements of the power supply. Use the tie wraps to dress the input cable wires; there
are two tie wrap tabs on the DC power sup ply.
The DC power supply unit is secured into the system chassis with two captive screws mounted on the
faceplate.
Cisco ASR 1002 Router DC Power Supply LEDs and Connector
Figure 2-17 shows the DC power supplies at the rear of the Cisco ASR 1002 Router. The Cisco
ASR 1002 Router supports up to two power supplies. The power supply LEDs and connectors on the rear
of the chassis are described in the Table 2-20.
