Connecting AC Power to an EX3200 or EX4200 Switch
The power supply in an EX3200 or EX4200 switch is a
Ensure that you have a power cord appropriate for your geographical location available to connect AC power to an EX3200 or EX4200 switch.
Before you begin connecting AC power to an EX3200 or EX4200 switch:
■Ensure that you have taken the necessary precautions to prevent ESD damage (see “Prevention of Electrostatic Discharge Damage on EX Series Switches” on page 236).
■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 98).
■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 130.
