Removing and Replacing a +24 VDC Power Supply in Cisco ASR 1002 Router
This section provides information about removing and replacing a +24 VDC power supply in the Cisco ASR
1002 Router.
Before you begin, read the following notices:
•
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,
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:
◦
Phoenix Contact 3.5mm flat-blade screwdriver or equivalent
◦
Wire-stripping tool for stripping 8-gauge wire
When you install the unit, the ground connection must always be made first and disconnected last. Statement
