Step 2 (cont.)
Connect DC Power
For DC powered models, you must supply your own power cables and one Phillips
screwdriver. DC power cables must have a wire gauge of at least 16 AWG and a 72
VDC, 6A rating. Remove the protective covers from the DC power terminal blocks. Use
the Phillips screwdriver to tighten the connections.
1. Connect a ground wire from the chassis ground to the rack.
2. Connect one end of another ground wire at the ground connector at Power 1
on the device chassis. Then connect the other end of the ground wire to the
ground connection at the DC power source.
3. Connect the negative (– 48VDC) side of a DC power cable to the Power 1
terminal on the chassis, labeled with the minus symbol (–), and connect the
positive (0V) side of the DC power cable to the Power 1 terminal labeled with
the plus symbol (+). The negative (minus symbol) terminal is in the center, and
the plus terminal is to the right.
4. Connect the other ends of the negative side and the positive sides of the DC
cable to the negative and positive connectors of the power source.
5. If you want to connect to redundant power, repeat steps 3 and 4 for Power 2
and then connect the other ends to a separate power source.
Note: Be sure to connect the positive sides of the cables to the positive sides of the
power sources, and the negative sides of the power cables to the negative sides of the
power sources. The two power LEDs on the front panel light up to indicate that both
power sources are on.
