Environmental Requirements
Site Location
Use this chapter to plan the Telephony Modem installation.
Provide at least 0.25 inch (6.4 mm) clearance on each side of the unit for
proper ventilation and cooling.
Mount the Telephony Modem properly to prevent uneven mechanical loading
on the chassis. Improper mounting can cause premature failure and poten-
tially hazardous conditions.
When installed in a closed or multi-unit rack assembly, the operating temper-
ature inside the rack environment may be higher than ambient temperature.
Install the Telephony Modem in an environment where the ambient tempera-
tures 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 included wall-mount-
ing brackets. ARRIS recommends wall-mounting to a plywood surface.
