Connecting AC Power to an EX4550 Switch
The power supply in an EX4550 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 an EX4550 switch.
Before you begin connecting AC power to an EX4550 switch:
•
Ensure that you have taken the necessary precautions to prevent electrostatic discharge
(ESD) damage (see
“Prevention of Electrostatic Discharge Damage” on page 287
).
•
Ensure that you have connected the device chassis to earth ground.
CAUTION:
Before you connect power to the switch, a licensed electrician
must attach a cable lug to the grounding cable 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 the EX4550 switch to earth
ground before you connect it 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
