Figure 37: DC Power Supply in an EX3200 Switch

WARNING: DC-powered EX3200 switches are intended for installation only
in a restricted access location.
Before you begin connecting DC power to an EX3200 switch:
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.
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 EX3200 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
an EX Series Switch" on page
Install the power supply in the chassis. For instructions on installing a power supply in
an EX3200 switch, see "Installing a Power Supply in an EX3200 Switch" on page
Ensure that you have the following parts and tools available:
DC power source cables (12–14 AWG) with ring lug (Molex 190700067 or equivalent)
