7. After the lead wire is fully inserted, perform these steps:
8.
Repeat Steps 5 through Step 10 for each lead wire.
9. After inserting the ground wire, leave an extra service loop in the ground lead, as shown in Figure 32:
Cisco +24 VDC Power Supply Terminal Block Ground Lead Service Loop, on page 40 to ensure that
the ground lead is the last lead to disconnect from the power supply if a great deal of strain is placed
on all three leads.
10. After tightening the receptacle screw for the ground, and leaving the extra service loop in the ground
lead, use a cable tie to secure the three leads to the power supply faceplate tie-wrap tab, as shown in
Figure 32: Cisco +24 VDC Power Supply Terminal Block Ground Lead Service Loop, on page 40 ,
item 5.
11.
Turn on the branch source breaker.
12. Move the power supply Standby switch to the On (|) position. The power supply LEDs light when power
is supplied to the router.
DETAILED STEPS
Step 1 At the rear of the router, ensure that the power Standby switch is in the Standby position.
Step 2
Ensure that the positive and negative leads are disconnected from the site power source and the source circuit breaker
is turned off.
Step 3 Using a wire stripper, strip the recommended amount of wire insulation, which is 1.5 cm (0.6 inch) from the negative,
positive, and ground leads.
The stripping length is common to all types of wire used.
Note
Figure 26: Stripping Wire for the +24 VDC Terminal Block, on page 38 shows the wire strip and lead.

Remove the covering from exactly the specified length of each wire. If you strip too much of the covering,
exposed wire protruding from the terminal block will create an electrical hazard. If you strip too little of the
covering, the wire might not make a good contact with the terminal, or it might not be held securely in place
in the terminal. Danger
Step 4
Using a 3.5mm screwdriver, insert the screwdriver at an angle to release the spring while you install the stripped lead
wire as shown in
Figure 27: Inserting a Screwdriver Into the +24 VDC Power Supply Terminal Block, on page 38 .

Step 5 Carefully push the screwdriver at a forward angle until you relieve the spring contact.
Step 6 With the screwdriver still inserted, gently push the lead wire (ground lead first) in until the copper wire, as shown in
Figure 28: Cisco ASR 1002-X 24 VDC Power Supply Lead Wire Inserted into Terminal Block, on page 39 ,
is no longer visible (see Figure 29: Cisco ASR 1002-X 24 VDC Power Supply Lead Wire Fully Inserted, on
page 39 ).
