Step 1: Connect one end of the chassis grounding wire (coming
with the switch) to the grounding screw on the rear of the chassis and
the other end to the ground nearby.
Step 2: Connect the DC power terminals of the switch to –48 VDC
power supply through DC power cords, with NEG (-) connected to the
–48V output and RTN (+) connected to the working ground of the –48
VDC power supply.
Note:
To connect the power cord to the DC power terminals on the chassis,
loosen the screws on the terminals first, insert the connectors of the
power cord into the terminals, and tighten the screws.
Step 3: Check whether the PWR LED on the front panel of the
switch is ON. If the LED is ON, it shows the power cord is properly
connected.
Caution:
Before powering on the switch, you should properly connect the
grounding wire.
