The power supply in an EX3200 or EX4200 switch is a hot-removable and hot-insertable
field-replaceable unit (FRU) located on the rear panel: You can remove and replace it
without powering off the switch or disrupting switch functions.
Before you begin connecting AC power to an EX3200 or EX4200 switch:
Ensure that you have connected the switch chassis to earth ground.
CAUTION: Before you connect power to the switch, a licensed electrician must attach
a cable lug to the grounding and power cables that you supply. A cable with an incorrectly
attached lug can damage the switch (for example, by causing a short circuit).
To meet safety and electromagnetic interference (EMI) requirements and to ensure
proper operation, you must connect EX3200 and EX4200 switches to earth ground
before you connect them to power. For installations that require a separate grounding
conductor to the chassis, use the protective earthing terminal on the switch chassis to
connect to the earth ground. For instructions on connecting earth ground, see
"Connecting Earth Ground to an EX Series Switch" on page 141. An EX3200 or EX4200
switch gets additional grounding when you plug the power supply in the switch into a
grounded AC power outlet by using the AC power cord appropriate for your geographical
location (see "AC Power Cord Specifications for EX3200 and EX4200 Switches" on
page 102).
Install the power supply in the chassis. For instructions on installing a power supply in
an EX3200 or EX4200 switch, see "Installing a Power Supply in an EX3200 or EX4200
Switch" on page 132.
NOTE: Each power supply must be connected to a dedicated power source outlet.
Ensure that you have the following parts and tools available:
A power cord appropriate for your geographical location
To connect AC power to an EX3200 or EX4200 switch:
