Mounting

The G10 CMTS can be mounted in a 19-inch EIA RS-310-C equipment rack or a 23-inch AT&T
DATAPHONE equipment rack. You can install the CMTS into non-standard racks by using the
additional rail mounting bracket holes in the CMTS.
We recommend you use a cable organizer to assist with the routing of cables to and from the
equipment rack. You should mount the cable organizer after the CMTS is installed.
For thermal management, airflow enters into the lower front and sides of the CMTS chassis
and exits through the upper rear. As a result, a clearance of 3 to 6 inches is required on each
side of the CMTS. You can mount additional equipment directly on either the top or the
bottom of the CMTS without impacting system ventilation.
We recommend that you maintain proper clearance to the front and rear of the mounting
rack so that the CMTS can be easily accessed during maintenance. The recommended
clearance to the front and rear of the chassis is 3 feet an d 2 feet.
We recommend that you rack mount systems from the
bottom up to maintain the lowest possible center of gravity
of the entire rack with its equipment.
We recommend that you use an equipment shelf or tray
beneath the CMTS to support its weight. The shelf avoids
backward toppling of the rack and excess torque on the
mounting brackets.
We recommend that you locate neighboring equipment
such that its ventilation exhaust does not feed into the
CMTS air intakes.
