Figure 15 Cisco ASR 1002-X Router –48V DC Power Supply
Step 5 Insert the stripped end of the ground lead all the way into the ground lead receptacle on the –48V DC-input power
supply, and tighten the receptacle screw using a 3.5 mm flat-blade screwdriver to a torque of 0.5 to 0.6Nm.
Step 6 Insert the stripped end of the positive lead all the way into the positive lead receptacle and tighten the receptacle screw
using the same 3.5 mm flat-blade screwdriver. Repeat this step for the negative lead.
Note Make sure 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 4 through Step 6.
Step 7 After tightening the receptacle screw for the ground, positive, and negative DC-input leads, use a cable tie to secure the
three leads to the power supply faceplate.
Note When securing the ground, positive, and negative DC-input leads to the power supply faceplate, leave extra 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.
Step 8 Turn the branch circuit breaker on at your site and the turn the Standby switch to the On (I) position.
Step 9 Check that the power supply LEDs light when power is supplied to the router.
You have completed the procedure for connecting a –48V DC power supply in the Cisco ASR 1002-X Router.
