Installing an AC Power Supply in an EX9214 Switch

Before you install an AC power supply in the switch:

• Ensure you understand how to prevent Electrostac discharge (ESD) damage. See

Prevenon of

Electrostac Discharge Damage

Ensure that you have the following parts and tools available:

• ESD grounding strap

• Phillips (+) screwdriver, number 1

The AC power supply in an EX9214 switch is a hot-insertable and hot-removable eld-replaceable unit

(FRU) installed in the rear panel. Up to four AC power supplies can be installed in an EX9214 switch.

NOTE: Each AC power supply must be connected to a dedicated AC power source outlet and a

dedicated customer site circuit breaker.

To install an AC power supply in an EX9214 switch:

1. Aach the ESD grounding strap to your bare wrist, and connect the strap to the ESD point on the

chassis.

2. If the power supply slot has a cover panel on it, unscrew the screw on the side of the cover panel in

the counterclockwise direcon using the Phillips (+) screwdriver, number 1, and remove the cover

panel. Save the cover panel for later use.

3. Taking care not to touch power supply components, pins, leads, or solder connecons, remove the

power supply from its bag.

4. Flip the AC input switch next to the appliance inlet on the power supply faceplate to the O (O)

posion.

5. Check whether the release lever below the empty power supply slot is locked in the

counterclockwise direcon (see Figure 68 on page 217). If it is not, pull the spring-loaded locking pin

in the release lever away from the chassis and turn the release lever in the counterclockwise

direcon unl it stops, and then let go of the locking pin in the release lever, and ensure that it is

seated in the corresponding hole in the chassis.

6. Using both hands, slide the power supply straight into the chassis unl the power supply is fully

seated in the slot on the rear of the switch. The small tab on the metal housing that is controlled by

the release lever must be inside of the corresponding slot at the boom of the power supply (see
