Installing an AC Power Supply in an EX9214 Switch
The AC power supply in an EX9214 switch is a hot-insertable and hot-removable
field-replaceable unit (FRU) installed in the rear panel. Up to four AC power supplies can
be installed in an EX9214 switch.
Before you install an AC power supply in the switch:
•
Ensure you understand how to prevent Electrostatic discharge (ESD) damage. See
“Prevention of Electrostatic Discharge Damage” on page 329.
Ensure that you have the following parts and tools available:
•
ESD grounding strap
•
Phillips (+) screwdriver, number 1
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. Attach 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 direction using the Phillips (+) screwdriver,
number 1, and remove the cover panel. Save the cover panel for later use.
