Installing Rear Panels
Complete the following steps to install rear panels:
1. Place the panel at the rear of the chassis between the two threaded
strips. Align the panel so that the serial number faces into the chassis
and the screw holes are on the right.
2. Using a flathead screwdriver, screw the two screws through the rear
panel into the threaded strip holes.
Maintaining the Fan Filter
The brushless fan(s) on the rear of the SCXI chassis cool the chassis and
modules. To keep the fan effective, the fan filter(s) must be clean. Dust and
dirt accumulation reduces airflow, making the inside of the chassis hotter,
shortening the life of the chassis and modules. Complete the following
steps to clean the fan filter(s):
1. Power off the chassis.
2. Remove the power cord from the power entry module.
3. Place the chassis face down on a flat surface so that the fan is on top.
If the chassis is so heavily cabled that you cannot easily place it in this
position, leave the chassis as it is, but be careful to support the fan
during removal and reinstallation to avoid breaking the fan wires.
4. Remove the fan filter. Remove the four screws that secure the fan and
filter to the rear of the chassis. When removing the last screw, be
careful to hold the fan to avoid breaking the fan wires.
5. Clean the fan filter by moving the filter around under a gentle stream
of cold tap water until all the dust is removed. Dry the filter.
6. Replace the fan filter by aligning the fan and filter with the fan holes,
making sure that the label side of the fan is face down. Reinstall the
four screws and make sure the assembly is secure.
