Cisco ASR 1004 Hardware Installation Guide

Connecting the +24 VDC Power Supply to the Router
The +24 VDC power supply uses a spring-loaded terminal block. The input terminal block requires 8 AWG
multistrand wiring to support input current. Features are provided for strain relieving the input wires from the
terminal block on the front panel. The recommended branch circuit breaker for the Cisco ASR 1002-X Router
+24 VDC power supply is a 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 location. Unlike the polarity labels of the –48 VDC power supply (ground, positive,
and negative), the polarity labels on the +24 VDC are ground, negative, and positive, as shown in Figure
168: +24 VDC Power Supply for the Cisco ASR 1002-X Router Components, on page 358 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:
◦
Phoenix Contact 3.5 mm flat-blade screwdriver or equivalent
◦
Wire-stripping tool for stripping 8-gauge wire
