Power Supplies for the Cisco ASR 1002 Router
Cisco ASR 1002 24 VDC Power Supply
This section provides information about the +24 VDC power supplies on the rear of the Cisco ASR 1002
Router. The recommended branch circuit breaker for the Cisco ASR 1002 24 VDC power
supply is a 40 A UL listed circuit breaker.
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 identifiers are zero (0) on the left side of the chassis rear and one (1)
on the right side of the chassis rear. The power supply switch is a standby switch and is not considered
a disconnect.
The +24 VDC power supply uses a spring-loaded terminal block. The input terminal block requires
maximum 8AWG multi-strand wiring to support input current. 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 +24 VDC power supply. The +24 VDC power supply unit
is secured into the system chassis with two captive screws mounted on the faceplate.

Note
The +24 VDC power supply product is labeled at
+27 VDC input
because the typical battery float voltage
is +27V; but generically, these power systems can be l24 V and referred to as +24 VDC (see
Figure 2-14
).
