Replacing the DC Power Supply in Cisco ASR 1004 Router
The color coding of the DC input power supply leads depends on the color coding of the DC power source
at your site. Typically, green or green/yellow is used for ground (GND), black is used for negative (–) terminal
and red is used for the positive (+) terminal. Make certain the lead color coding you choose for the DC input
power supply matches lead color coding used at the DC power source.
Note
When you install the unit, the ground connection must always be made first and disconnected last. Statement

Warning
To install the DC power supply, follow these steps:
SUMMARY STEPS
1. Make certain that the chassis ground is connected before you begin installing the DC power supply.
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.
3. Tighten the captive screws on the power supply.
4. Locate the power supply terminal block and remove the plastic cover from the terminal block:
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).
6. Attach the GND wire first and follow this order:
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
8. Insert the positive ground cable. Replace the ground lug with cable in the following order:
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).
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.
11. Replace the terminal block plastic cover and tighten the screws. The plastic cover slides in easily over
the terminal block.
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.
13. Switch the power supply circuit breaker switch to the On (|) position.
