Environmental Requirements
Site Location
Use this chapter to plan the Telephony Modem installation.
Installation of the equipment in a rack should not restrict airflow. In
particular, provide adequate side clearance.
Mount the Telephony Modem properly to prevent uneven mechanical
loading on the chassis. Improper mounting can cause premature failure
and potentially hazardous conditions.
When installed in a closed or multi-unit rack assembly, the operating
temperature inside the rack environment may be higher than ambient
temperature. Install the Telephony Modem in an environment where
the ambient temperatures remains below 50° Celsius.
Note:
Install the Telephony Modem in a restricted access location.
The Telephony Modem is designed to be installed in a wiring closet
rack. The wiring closet must provide access to power, telephony, and
network facilities as described in this chapter.
The Telephony Modem can be wall-mounted using the rack-mounting
brackets (recommended) or the cutouts on the bottom of the Telephony
Modem. ARRIS recommends wall-mounting to a plywood surface.
