Powering On a DC Switch
Perform this procedure to power on a DC 8100S Series switch:
Warning
As a safety precaution, install a circuit breaker with a minimum value
of 15 Amps between the equipment and the DC power source.
Always connect the wires to the LAN equipment first before you
connect the wires to the circuit breaker. Do not work with HOT feeds
to avoid the danger of physical injury from electrical shock. Always
be sure that the circuit breaker is in the OFF position before
connecting the wires to the breaker.  E9
Warning
For centralized DC power connection, install only in a restricted
access area.  E23
Note
A tray cable is required to connect the power source if the unit is
powered by centralized DC power. The tray cable must be a UL
listed Type TC tray cable and rated at 600 V and 90 degrees C, with
three conductors, minimum 14 AWG.  E24
