32 Juniper Networks G10 CMTS Getting Started
Ensure that you have read and taken the proper safety
precautions as described in the Juniper Networks G10 CMTS
Installation and Configuration manual prior to connecting
any power source to the G10 CMTS.
Each AC power transition module in the G10 CMTS chassis contains a standard IEC 15-A
three-prong male AC power receptacle for connecting to an AC power source (refer to
Figure 3 on page 4). Facing the rear of the chassis, the AC power transition modules on the
right and left sides of the chassis independently support the power supplies in Domain A and
Domain B, respectively.
To enhance the redundancy capabilities, each power
transition module must be powered by sources on
different circuits.
The following procedure describes the steps for connecting the AC power transition modules
to their power sources (refer to Figure 17 on page 33):
1. Ensure that the rocker switch on each AC power transition module is in the OFF (O)
position.
2. Swing the power cord retainer clips to their upright position, plug the female end of each
15-A power cord supplied with your shipment into the AC power receptacle on each AC
power transition module, then close the retainer clips so that they clasp around the
power cords.
3. Plug the male end of each 15-A power cord to independent power sources. Always use
AC power sources that support the ground prong of the power cord.
The G10 CMTS power supplies are autosensing which
enables them for usage with 110 VAC or 220 VAC.
