Connecting AC Power to an EX-series Switch
The power supply in an EX 3200 or EX 4200 switch is a hot-removable and
hot-insertable field-replaceable unit (FRU) located on the rear panel.
CAUTION: To meet safety and electromagnetic interference (EMI) requirements and
to ensure proper operation, you must connect EX 3200 and EX 4200 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. An EX-series
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, Connection, and Power Cord Specifications EX
3200 and EX 4200 Switches).
Ensure that you have the following parts and tools available to connect AC power to
an EX 3200 or EX 4200 switch:
Electrostatic discharge (ESD) grounding strap
Power cord appropriate for your geographical location
Before you begin connecting AC power to an EX 3200 or EX 4200 switch:
Ensure that you have taken the necessary precautions to prevent ESD damage
(see Prevention of Electrostatic Discharge Damage on EX-series Switches).
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 EX 3200 and EX 4200 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.
Install the power supply in the chassis. For instructions on installing a power
supply in an EX 3200 or EX 4200 switch, see Installing a Power Supply in an EX
3200 or EX 4200 Switch.

Ensure that the power supplies are fully inserted in the chassis and the screws on their faceplates are tightened. Squeeze the two sides of the power cord retainer clip, and insert the L-shaped ends of the wire clip into the holes in the bracket on each side of the AC appliance inlet on the AC power supply faceplate (see Figure 1 on page 2).
