12 Juniper Networks G10 CMTS Getting Started
The G10 CMTS chassis must be rack mounted prior to the
installation of any additional power supplies or modules.
Never power on the G10 CMTS without first grounding the
chassis.
1. The G10 CMTS accessory kit contains a two-ring lug connector that must be crimped to
the earth ground strap.
2. Using the two supplied #10 hex bolts, attach the two-ring lug connector of the ground
strap to the chassis using 20 in lb of torque on each bolt. Figure 3 on page 4 shows the
location of the chassis ground nuts on the chassis.
3. Ensure that proper clearance is maintained between the G10 CMTS chassis and its
surroundings to allow adequate air ventilation to flow into the air intakes and out of the
air exhaust:
A minimum of 3 feet (0.91 m) between the front of the chassis and any other object
A minimum of 2 feet (0.61 m) between the rear of the chassis and any other object
A minimum of 3 inches between each side of the chassis and any other object
The G10 CMTS does not require any clearance between
the bottom of the chassis and the floor. Similarly, there are
no clearance requirements between the top of the chassis
and the bottom of another G10 CMTS stacked above it on
the same rack.
4. It is recommended that an equipment shelf be installed into the rack that can support
the maximum weight (140 lb, or 64 kg) and dimensions of the chassis. The chassis
dimensions, when viewed from the bottom, are provided in Figure 6.
