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 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 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 locate neighboring equipment	•
	such that its ventilation exhaust does not feed into the	•
	CMTS air intakes.	•
		•
		•
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 and 2 feet.
