Juniper EX3200 Connecting

Connecting AC Power to an EX3200 or EX4200 Switch
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. 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).
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.
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:

on their faceplates are tightened.
Squeeze the two sides of the power cord retainer clip and insert the L-shaped
2.
ends of the wire clip into the holes in the bracket on each side of the AC power
cord inlet on the AC power supply faceplate (see Figure 1).
Locate the power cord or cords shipped with the switch; the cords have plugs
