The G10 CMTS is designed for mounting in a 19-inch EIA RS-310-C equipment rack or a
23-inch AT&T DATAPHONE equipment rack. Installation into non-standard racks may still be
accomplished through the additional rail mounting bracket holes provided with the CMTS.
Systems should be rack mounted from the bottom up to
maintain the lowest possible center of gravity of the entire
rack with its equipment.
An equipment shelf or tray is recommended beneath the
CMTS to support its weight. The shelf avoids any backward
toppling of the rack or excess torque applied to the
mounting brackets when the CMTS is installed.
A cable organizer is recommended to assist with the routing of cables to and from the
equipment rack. The cable organizer should be mounted after the CMTS is installed.
For thermal management, airflow enters from the lower front and sides of the CMTS chassis
and ventilates through the upper rear. As a result, a clearance of 3 to 6 inches is required on
each side of the CMTS. Additional equipment can be mounted flush on either the top or
bottom of the CMTS without impacting system ventilation.
Neighboring equipment must be positioned such that its
ventilation exhaust does not feed into the CMTS air
intakes.
Proper clearance to the front and rear of the mounting rack is recommended so that the
CMTS can be easily accessed during maintenance. The recommended clearance to the front
and rear of the chassis is 3 feet and 2 feet, respectively.
