Connecting DC Power to an EX2200 Switch
The power supply is built in along the rear panel.
WARNING: DC-powered switches are intended for installation only in a
restricted access location.
Before you begin connecting DC power to the 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 cablewith an incorrectly attachedlugcandamage the switch(forexample,
by causing a short circuit).
To meet safety and electromagnetic interference (EMI) requirements and
to ensure proper operation, you must connect the switch 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” on page 117.
NOTE: Grounding is required for DC systems and recommended for AC
systems. An AC-powered 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.
