Replacing a Power Supply

Removing and Installing an AC Power Supply

The Juniper Networks appliance ships with one AC power supply installed in the back of

the chassis. You can add an optional second power supply to support redundancy and

load-sharing features. In addition, if you need to replace one of the power supplies, you

can “hot-swap” the faulty power supply for a replacement while the optional second

power supply assumes responsibility for the entire power load, thus avoiding a situation

where you have to power off the Secure Access Service before replacing the removable

unit.

To remove and install an AC power supply module:

1. Press the release trigger in and to the right to release the module.

2. Grasp the insertion and removal handle and pull the power supply module straight

out of the chassis.

Once you have removed the supply module, be sure to replace it with a replacement

power supply or the “dummy” power supply port cover installed in your chassis at the

time of shipping.

3. Line the new power supply module up with an empty power supply port on the back

of the chassis.

4. Slowly slide the power supply module into the chassis until it clicks into place.

Removing and Installing a DC Power Supply

To remove and install a DC power supply module:

1. Unplug the power cord.

2. Disconnect the DC supply wires from the lugs on the DC power supply.

3. Press the release trigger in and to the right to release the module.

4. Grasp the power supply module and pull it straight out of the chassis.

5. Slowly slide the new module into the chassis until it clicks into place.

6. Connect the DC supply wires to the module using the lugs. Be sure to attach the ground

wire.

7. Attach the power cord
