Installing a Power Supply in an EX3200 or EX4200 Switch
The power supply in EX3200 and EX4200 switches is a hot-removable and
hot-insertable field-replaceable unit (FRU): You can remove and replace it without
powering off the switch or disrupting switch functions.
Ensure that you have the following parts and tools available to install a power supply
in an EX3200 or EX4200 switch chassis:
■ Electrostatic discharge (ESD) grounding strap
■ Phillips (+) screwdriver, number 2
Before you begin installing a power supply in an EX3200 or EX4200 switch, ensure
that you have taken the necessary precautions to prevent ESD damage (see
“Prevention of Electrostatic Discharge Damage on EX Series Switches” on page 236).
To install a power supply in an EX3200 or EX4200 switch (see Figure 46 on page 131):
1. Attach the electrostatic discharge (ESD) grounding strap to your bare wrist, and
connect the strap to the ESD point on the chassis.
2. Taking care not to touch power supply components, pins, leads, or solder
connections, remove the power supply from its bag.
3. Loosen the locking lever screw on the left front of the power supply by using the
Phillips (+) screwdriver, number 2.
4. Push down on the locking lever until it is in its lowest position.
5. Using both hands, place the power supply in the power supply slot on the rear
panel of the switch and slide it in until it is fully seated.
