DETAILED STEPS
Step 1
At the rear of the router, check that the power supply Standby switch is in the Standby (see Figure 167: Cisco ASR
1002-X Router –48 VDC Power Supply Terminal Block Cable Connections, on page 357 ) position.

Step 2
Ensure that the negative and positive leads are disconnected from the site power source.
Step 3
Using a wire stripper, strip approximately 0.55 inch (1.39 cm) from the negative, positive, and ground lead.
Step 4
Insert the stripped end of the ground lead all the way into the ground lead receptacle on the –48 VDC input power supply,
and tighten the receptacle screw using a 3.5 mm flat-blade screwdriver to a torque of 0.5 to 0.6 Nm.
Step 5
Insert the stripped end of the positive lead all the way into the positive lead receptacle and tighten the receptacle screw
using the same 3.5mm flat-blade screwdriver.
Step 6
Repeat this step for the negative lead.
Ensure the entire stripped end of each lead is inserted all the way into its receptacle. If any exposed wire at the
stripped end of a lead is visible after inserting the lead into its receptacle, remove the lead from the receptacle,
use the wire stripper to cut the stripped end of the lead, and repeat Step 3 through Step 6.
Note
Step 7
After tightening the receptacle screw for the ground, positive, and negative –48 VDC-input leads, use a cable tie to secure
the three leads to the power supply faceplate, as shown in Figure 167: Cisco ASR 1002-X Router –48 VDC Power Supply
Terminal Block Cable Connections, on page 357. When securing the ground, positive, and negative –48 VDC-input
leads to the power supply faceplate, leave a small service loop in the ground lead 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, as shown in Figure 167:
Cisco ASR 1002-X Router –48 VDC Power Supply Terminal Block Cable Connections, on page 357.
Ensure that the ground lead wire has a service loop before you tie wrap the lead wires to prevent the ground
from being disconnected.
Caution
Step 8
Connect the ground, positive, and negative leads to the power source.
Step 9
Turn the branch source breaker on.
Step 10
Place the –48 VDC Standby switch in the On (|) position. The power supply LEDs light when power is supplied to the
router.
