Air Flow
Air Flow
The NV5128 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 filters.
Fan Cleaning and Replacement
One plug-in fan tray containing cooling fans is located at the top of the router frame (when viewing
from the front). 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 the tray 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 intake filter is located on the front door assembly of the NV5128 Multi-Format Router. To
access the filter open the router door by releasing the two thumbscrew locks. Remove the upper
module brace by loosening the two ¼ turn screws, then slide the filter up and to the right to remove
it. This process may be easier if the entire door is removed by lifting 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, a vacuum cleaner or compressed air may be used for clean-
ing purposes. 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 indicator on the control card turns on, 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.
Call Miranda for replacement battery information. For contact information, see Technical Support

Caution If airflow is impeded overheating may occur.
