Figure 28: 1200 W DC Power Supply
Airflow enters from the front vents on the 1200 W DC power supply and exits to the rear vents of the
switch. Airflow through the 1200 W DC power supply is independent of the airflow that exists through
the rest of the switch.
The input DC cable is 10 feet (3 meters) long, with an input connector on one end and precut wire on
the other end that goes to the DC power source (
see the following figure
). The connector end has a
locking mechanism that locks onto the DC power supply to prevent accidental removal of the input DC
cable.
