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 cable lug to the grounding and power cables that you supply.
