which the switch is mounted.
3. Place the grounding lug attached to the grounding cable over the protective earthing
terminal on the protective earthing terminal bracket.

Connecting AC Power to an EX4600 Switch
The power supply in an EX4600 switch is a hot-removable and hot-insertable
field-replaceable unit (FRU). You can remove and replace it without powering off the
switch or disrupting switch functions.
Ensure that you have a power cord appropriate for your geographical location available
to connect AC power to the switch.
Before you begin connecting AC power to the switch:
•
Ensure that you have taken the necessary precautions to prevent electrostatic discharge
(ESD) damage (see “Prevention of Electrostatic Discharge Damage” on page 120).
•
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 cablelug to the grounding and power cables that you supply.
