Air Flow

Air Flow

The NV8256-Plus draws cooling air from the front of the router, through the door, and exhausts
heated air through the rear of the frame. The router must have the door properly installed and closed
for proper airflow through the chassis. For maximum air flow, regularly inspect router fans and fil-
ters.

Fan Cleaning and Replacement

One plug-in fan tray containing three cooling fans is located at the top of the router frame. The tray
can be removed for inspection or cleaning by opening the frame front door, sliding the latches that
hold the fan module in place, and pulling the module out of the frame. If the fans become dusty or
clogged with lint, use a vacuum or compressed air to clean the dust off. Also check the openings at
the back of the frame where air enters and exits to be sure dust and lint have not accumulated.

The fan tray is easily replaced simply by sliding it out of the front of the frame and inserting a new
tray. The fans on the tray are held in place by four screws and a pluggable connector. To replace the
fans, remove the screws and unplug the connector.

Intake Filter Screen Cleaning

The NV8256-Plus has three fan filters. Two intake filters are located on the front door assembly. To
access the filters, open the router door by releasing the two thumbscrew locks and then slide the fil-
ters up and to the right to remove. This process may be easier if the entire door is removed by lift-
ing it straight up while open.

The system can be operated safely with the door removed for short periods of time. If the filter is
only lightly contaminated with debris, clean the filter by vacuuming up loose debris or by blowing
air from the clean side to the dirty side. For filters badly loaded with debris, rinse with cold water or
wash with warm water and mild detergent. Be sure the filter is completely dry before re-installing
it.

Battery Replacement

If the red Low Battery LED indicator on the control card is lit, the battery located on the front edge
of the card needs replacing. Grasp the exposed edge of the battery with your fingers and pull it
towards you to remove it.

Caution

If airflow is impeded overheating may occur.

Important

Do not use a metallic tool to remove the battery.
