Replacement procedures

This chapter provides information about replacing components on the router.

Replacing a power supply system

ARNING!

• Power supplies for the router are hot-swappable. When hot-swapping a power supply, make sure the

other power supply is operating properly. When installing and replacing a power supply with the

router powered on, pay attention to the operation procedures and electricity safety issues. To avoid

injury, do not touch any wires, terminals, or parts with a high-voltage hazard sign.

• Hold the power supply by the bottom when moving it. Do not lift the module by the handle.

To prepare for the replacement:

1. Put on an ESD-preventive wrist strap and make sure it makes good skin contact and is well

grounded.

2. Make sure the power switch of the DC or AC power supply is in the OFF position before

removing it.

3. Remove the cables connected to the DC or AC power supply.

Replacing a DC power supply

1. Use a Phillips screwdriver to loosen the captive screws on both sides of the power supply,

remove the air filter frame of the power supply, and pull out the handle of the power supply.

2. Supporting the bottom of the power supply with one hand and holding the power supply

handle with the other hand, gently pull the DC power supply out along the slide rails.

Put the removed power supply on an antistatic mat or its original shipping materials.

3. Remove the air filter frame of the new power supply, and pull out the handle.

HP recommends that you place a removed module in an antistatic bag or its original shipping

materials.

4. Slowly push the new power supply into the slot along the slide rails until the rear side of the

power supply has close contact with the backplane.

5. Use a Phillips screwdriver to fasten the captive screws on both sides of the power supply panel,

and install the air filter frame of the power supply.
