Removing the +24 VDC Power Supply from Cisco ASR 1002 Router
Before you can remove a +24 VDC power supply from the Cisco ASR 1002 Router, you must remove
input power going to the power supply.
Caution
Make certain that the chassis ground lead wire is connected before you begin removing and installing
the power supply.
To remove the +24 VDC power supply from the Cisco ASR 1002 Router, follow these steps:
Step 1
Slip on the ESD-preventive wrist strap that was included in the accessory kit.
Step 2
Place the power supply Standby switch in the Standby (see
Figure 14-60
, item 6) position.
Step 3
Using the recommended screwdriver, insert the screwdriver at an angle, pushing forward to release the
internal spring contact on the lead wire and then gently pull out the wire.
The screwdriver remains pushed into the spring release opening until the wire is completely removed.
Step 4
Remove screwdriver and continue removing the remaining lead wires from the terminal block, repeating
Step 4 through Step 5 for each lead wire.
Tip
If the 8-gauge input wiring is very rigid or a solid wire, then a screwdriver might not be necessary. As a
result of using few-strand heavy gauge wiring, you can insert the wire into the terminal block to release
the spring tension. After inserting the lead wire, gently pull on the wire to make certain that the wire is
secured. Make certain that no wire is exposed and that only wire insulation is seen.
