Connecting DC Power to an EX4500 Switch
You can install two DC power supplies in an EX4500 switch. After you have installed at
least one power supply, you can connect power to the switch.
WARNING: Before performing DC power procedures, ensure that power is
removed from the DC circuit. To ensure that all power is off, locate the circuit
breaker on the panel board that services the DC circuit, switch the circuit
breaker to the OFF position, and tape the switch handle of the circuit breaker
in the OFF position.
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).
CAUTION: Mixing different types (AC and DC) of power supplies or power
supplies with front-to-back or back-to-front airflow in the same chassis is
not supported.
