Connect DC Power to an EX4100 Switch
Before you begin connecng DC power to the switch, ensure that you have connected earth ground to
the switch chassis.
CAUTION: To meet safety and electromagnec interference (EMI) requirements and to
ensure proper operaon, you must connect the switch to earth ground before you
connect them to power. For installaons that require a separate grounding conductor to
the chassis, use the protecve earthing terminal on the switch chassis to connect to the
earth ground. For instrucons on connecng earth ground, see "Connect Earth Ground

Ensure that you have taken the necessary precauons to prevent electrostac discharge (ESD) damage
(see Prevenon of Electrostac Discharge Damage ).
Before you connect power, install the power supply in the chassis. For instrucons on installing a DC
power supply in an EX4100 switch, see "Install a DC Power Supply in an EX4100 Switch" on page 187.
Ensure that you have the following parts and tools available:
• DC power source cables (14–16 AWG) (not provided)
