Figure 17: AC Power Cord and Retainer Clip
DC Power
Each DC power transition module in the G10 CMTS chassis contains a terminal block for
connecting to a DC power source (refer to Figure 18 on page 34). Unlike the AC
configuration, the DC power transition modules do not operate independently. Each DC
power transition module supports the power supplies in both domains of the chassis.
The following procedure describes the steps for connecting the DC power transition modules
to their power sources:
1.
2.
3.
To enhance the redundancy capabilities, it is
recommended that each power transition module be
powered by sources on different circuits.
Shipped with the G10 CMTS are ring lugs that are used to connect the DC power cord to
the DC power transition module terminal block. These ring lugs must be crimped to the
negative (–) and positive (+) wires of the DC power cord in order to properly connect to
the DC power transition module.
Remove the screw from the negative (–) terminal on the terminal block of the DC power
transition module, insert the screw through the ring lug of the power cord that will be
attached to the negative (–) terminal of the DC power source, and tighten the screw into
the negative (–) terminal on the terminal block. Apply 20 in lb of torque to the screw.
Remove the screw from the positive (+) terminal on the terminal block of the DC power
transition module, insert the screw through the ring lug of the power cord that will be
attached to the positive (+) terminal of the DC power source, and tighten the screw into
the positive (+) terminal on the terminal block. Apply 20 in lb of torque to the screw.
