Fan Tray Module (Optional)

The Mediant 1000 features an optional fan tray module (mandatory for the partner
application platform). The extractable fan tray contains six 5V fans, each fan's dimensions
being 40 mm x 40 mm x 20 mm.
The fan tray unit is located to the extreme right, when facing the front panel (refer to
2-2 on page 26).
The fan tray unit draws air in by six fans through a perforated grill at the right side of the
chassis. The incoming air passes through a removable filter, whose honeycombed design
prevents RF interference. The clean air passes through the entire set of modules cooling
each one and exits the Mediant 1000 via perforated vents on the left side of the chassis.
Blank panels are used to cover all unoccupied slots on the front and rear sides of the
chassis. The blank panels are especially constructed to assist optimal air flow within the
chassis.

Replacing the Air Filter

The fan try module includes a removable air filter (located within the fan assembly,
immediately inside the perforated grill). The air filter should be replaced approximately
every 90 days and should be checked weekly to ensure it is not saturated and require
cleaning / replacement. You should clean the air filter no more than three times, after which
the air filter requires replacement.
The air filter removed from the fan try unit is shown in
Cleaning or replacing the air filter can be carried out while the system is fully functioning.
Warning:
To clean / replace the air filter, take these 7 steps:
Release the two screws on the top right-hand corner and the bottom right-hand corner

of the front panel of the fan tray unit.
Warning:
Version 4.6
It is imperative to cover all unoccupied slots in the front and rear panels of
the chassis with blank panels to maintain internal airflow pressure.
Prepare all the equipment you need to clean the air filter before
removing it for cleaning. It is imperative that the chassis does not
remain without the fan tray unit for a long period of time. Be sure
to reinsert the fan tray unit while you are cleaning the air filter and
reinsert the air filter as soon as it is clean.
When removing the fan tray unit, the fans continue to rotate at a
high speed. Use caution not to touch the rotating fan blades.
