Preventive Maintenance
Cleaning the fan filter
Periodically clean the filter on the Fan Tray Assembly (see
figure 2
on page 18). The frequency of cleaning
depends on the environmental conditions of where your equipment is located. Clean filter with a mild deter-
gent and water, then air-dry, or you can use compressed air. It should be completely dry before reuse.
Spare filters (part no. 6670-AF-6) are available from Patton Electronics Company.
Troubleshooting
System won’t power up
If the green LED on the power supply module does not light up, you should: remove the power supply module
from the chassis, then plug it back in, making sure it is seated properly. If the green LED still does not illumi-
nae, verify that the polarity is wired correctly at the back of the chassis.
If the green LED lights up on the power supply module, but the system still isn’t powering-up, then the mod-
ule may be faulty and should be returned to the manufacturer.
