Removing and Replacing FRUs from the Cisco ASR 1000 Series Routers
DETAILED STEPS
Step 1
Make certain that the chassis ground is connected before you begin installing the DC power supply.
Step 2 Grasp the DC power supply by the two handles and carefully slide it into the chassis. Make sure you align the rear
connector to the backplane until it is fully seated.
Step 3 Tighten the captive screws on the power supply.
Step 4
Locate the power supply terminal block and remove the plastic cover from the terminal block:
a) Unscrew and remove the two #10 screws.
b) Slide the cover off the terminal block towards the right.
Caution
Step 5
You must wrap the positive and negative cables with sleeving. Take each ground wire and cover the area from the lug
to the wire with heavy shrink sleeving (see xref fig).
Step 6
Attach the GND wire first and follow this order:
a) Flat Washer
b) Ground lug with grounding wire
c) KEPnut screw
Step 7 Tighten the KEP-style hex nut screws (use the screwdriver to tighten the ground screw in the terminal block to a torque
of 18-22 in-lbs) on the power supply studs
Step 8
Insert the positive ground cable. Replace the ground lug with cable in the following order:
a) Flat Washer
b) Ground lug with positive wire
c) Kepnut screw
Step 9 Tighten the KEP-style hex nut screws (use the screwdriver to tighten the positive ground screw in the terminal block
to a torque of 18-22 in-lbs) on the power supply ground studs and repeat the same steps for the negative ground stud
and wire (see xref fig).
Secure the wires coming in from the terminal block so that they cannot be disturbed by casual contact.
Note
Step 10 Use tie wraps to secure the wires, so that the wires are not pulled from the terminal block by casual contact. Tie-wrap
studs are located below the power supply terminal block.
Note The ground wire must contain a loop when securing it to the tie-wrap tab to prevent it from being pulled out.
Step 11
Replace the terminal block plastic cover and tighten the screws. The plastic cover slides in easily over the terminal
block.
Step 12
If you taped the circuit breaker, then remove the tape from the circuit-breaker switch handle and move the circuit-breaker
handle to the on position.
Step 13
Switch the power supply circuit breaker switch to the On (|) position.
What to do next
This completes the procedure for connecting the DC power supply in the Cisco ASR 1004 Router.
Before you continue to install the terminal block ground wires, stop and perform Step 5 to prevent any
contact with metal lead on the ground wire and the plastic cover.
