iPlex Installation and Hardware Specification Guide
31
DC Power and
Grounding
Requirements
The chassis has only one power terminal with no redundant connection points for
two CO power sources.
ATTENTION!
It is important to maintain proper air circulation through the iPlex
chassis. Failure to maintain proper air flow and adequate air space
can cause the iPlex to overheat and fail. Since the iPlex airflow is
from side-to-side it is recommended that you maintain a minimum 6-
inch (15 cm) clearance on both sides between the chassis air intake
and air exhaust on the sides and a cabinet wall or other barrier. You
should also calculate the heat load from other heat generating
devices and determine if an off-set is required between units to mini-
mize the effects of heat exhaust. Always allow a minimum separation
between the hot air exhaust on one chassis and the air intake on
another chassis.
