Cisco ASR 1001 Hardware Installation Guide

Replacing the +24 VDC Power Supply in Cisco ASR 1002 Router
The +24 VDC power supply uses a spring-loaded terminal block. The input terminal block requires 8 AWG
multi-strand wiring to support input current. Features are provide for strain relieving the input wires from the
terminal block on the front panel. The recommended branch circuit breaker for the Cisco ASR 1002 Router
+24 VDC power supply is 40 A UL listed circuit breaker.
Before you begin, read these important notices about the +24 VDC power supply:
•
The labeling displays +27 VDC INPUT. This labeling describes the nominal voltage provided at a cell
site.
• Observe the polarity—Unlike the polarity labels of the –48 VDC power supply (ground, positive,
negative), the polarity labels on the +24 VDC are ground, negative, positive as shown in xref fig from
right to left as they appear on the actual power supply unit.
•
The ground (GND) lead is always installed first and removed last.
•
The +24 VDC power supply uses a spring loaded terminal block; therefore have the recommended
screwdriver size available.
•
Review the diagrams to see how the wire is stripped and how the screwdriver is inserted at an angle into
the terminal block.
•
Have the following equipment available to install and remove the +24 VDC power supply:
◦
3.5mm flat-blade screwdriver
◦
8-gauge wire
