Fans - Alcatel 7450 ESS-7 Installation Manual

Fans

The 7450 ESS-7 cooling system must have at least 3-inches at the rear and on the right-hand side
of unrestricted unobstructed air flow to function properly. 9-inches are recommended.
The fan tray must be in place before the chassis is powered on.
Blank panels and faceplates are required in all empty card and component slots to prevent excess
dust accumulation and to help control airflow and electromagnetic interference.
Filters
The filter tray must always be installed while the 7450 ESS-7 is powered up.
The filter should be inspected monthly and cleaned and replaced every twelve months or as
required. The filter is field replaceable.
