NOTE: If you mounted the switch on four posts of a rack using the
four-post rack-mount kit, the protective earthing terminal on the switch
is accessible through the slot on the left rear bracket.
The protective earthing terminal on the switch mounted on four posts is
available only if the rack is 27.5 in. (approximately 70 cm) deep through
30.5 in. (approximately 77.5 cm) deep for a switch mounted flush with
the rack front and 29.5 in. (approximately 75 cm) deep through 32.5 in.
(approximately 82.5 cm) deep for a switch mounted 2 in. (approximately
5 cm) recessed from the rack front.

Secure the grounding lug to the protective earthing terminal with screws.
4.
Dress the grounding cable and ensure that it does not touch or block access to other
switch components and that it does not drape where people could trip over it.

Connecting AC Power to a J-EX4500 Switch
The AC power supply in a J-EX4500 switch is a hot-removable and hot-insertable
field-replaceable unit (FRU). After you have installed at least one power supply, you can
connect power to the switch.
CAUTION: Operating the switch with an incorrect power supply might cause
the chassis to overheat. See “Installing a Power Supply in a J-EX4500 Switch”
on page 88.
CAUTION: To meet safety and electromagnetic interference (EMI)
requirements and to ensure proper operation, you must connect the 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 the switch to ground using a
separate grounding conductor, see “Connecting Earth Ground to a J-EX Series
Switch” on page 99.
The 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 a J-EX4500 Switch” on page 65.
