Installing a Power Supply in an EX4500 Switch
The power supply in EX4500 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.
Before you install an AC power supply in the switch:
■ Ensure you understand how to prevent ESD damage. See “Prevention of
Electrostatic Discharge Damage on EX Series Switches” on page 174.
NOTE: Each power supply must be connected to a dedicated power source outlet.
To install a power supply in the switch (see Figure 28 on page 75):
1. Ensure that you have the correct power supply. The color of the power supply's
ejector lever must match the color of the intake or exhaust labels visible through
the fan tray vents. See “AC Power Supply in EX4500 Switches” on page 18.
CAUTION: Operating the switch with an incorrect power supply might cause the
chassis to overheat.
2. Attach the electrostatic discharge (ESD) grounding strap to your bare wrist, and
connect the strap to the ESD point on the chassis.
3. If the power supply slot has a cover panel on it, pull the handle of the cover panel
outwards and remove it. Save the cover panel for later use.
4. Taking care not to touch power supply pins, leads, or solder connections, remove
the power supply from the bag.
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. You will hear a distinct
click sound when the power supply is fully seated n the chassis.
