Connecting AC Power to an EX2200 Switch
The power supply in an EX2200 switch is located on the rear panel.
Ensure that you have the following parts and tools available:
■A power cord appropriate for your geographical location
■A power cord retainer clip
Ensure that you have connected the switch chassis to earth ground.
CAUTION: To meet safety and electromagnetic interference (EMI) requirements and
to ensure proper operation, you must connect the 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. An EX2200 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 EX2200 Switches).
To connect AC power to the switch:
1. Squeeze the two sides of the power cord retainer clip and insert the L-shaped
ends of the wire clip into the holes in the bracket on each side of the AC power
cord inlet on the rear panel (Figure 1).
The power cord retainer clip extends out of the chassis by 3 in.
2. Locate the power cord or cords shipped with the switch; the cords have plugs
appropriate for your geographical location. See AC Power Cord Specifications
for EX2200 Switches.
WARNING: Ensure that the power cord does not drape where people can trip on it
or block access to switch components.
3. Insert the coupler end of the power cord into the AC power cord inlet on the rear
panel.
4. Push the power cord into the slot in the adjustment nut of the power cord retainer
clip. Turn the nut until it is tight against the base of the coupler and the slot in
the nut is turned 90° from the top of the switch (see Figure 2).
5. If the AC power source outlet has a power switch, set it to the OFF (0) position.
6. Insert the power cord plug into an AC power source outlet.
7. If the AC power source outlet has a power switch, set it to the ON (|) position.
