Preventative Maintenance Central Station Chassis and Wireless Telemetry Server Chassis
5.2 Central Station Chassis and Wireless Telemetry
Server Chassis
The following internal cleaning procedures should only be performed by a trained, qualified
electronic technician.
Turn off the AC power and unplug the AC main power cord and all other cables from the
rear panel from the Panorama Central Station before attempting internal cleaning. Clean the
monitor in an area free of blowing dust, dirt, and lint.
5.2.1 Cover Removal
Using a Phillips #2 screw driver, remove the four (4) or six (6) screws holding the cover in
place. These screws are located on the back of the chassis along the cover’s edge, two per
side. Once the screws are removed, slide off the cover. Remove the front cover by grasping it
by the bottom and lifting up and out.
5.2.2 Cleaning
Use an anti-static vacuum to carefully remove accumulated dust, dirt, and lint from the various
internal surface areas. Be careful not to dislodge components, connectors, or printed circuit
boards.
5.2.3 Visual Inspection
Perform a visual check to verify that all dust, dirt, and lint has been completely removed, and
that connectors and printed circuit boards (PCBs) are properly seated.
5.2.4 Fan
If the power supply fan or the auxiliary fan is noisy or turns too slowly, replace that
component. The Power Supply should be replaced as an assembly, rather than replacing its
internal fan.
5.2.5 Motherboard Backup Battery Replacement
Locate the battery (BT1) on the motherboard. Remove the battery from its socket and install a
new battery, observing the proper polarity. The Tower's CMOS settings will probably have
reset to the manufacturer’s defaults. They must be changed to meet the requirements of
Panorama. This must be accomplished prior to returning the unit to use. See ‘‘Panorama
Motherboard CMOS Setup/Verification’’ on page 7-2.
5.2.6 Cover Replacement
Snap the front cover back on and slide the cover in place. Then, re-install the four (4) or six
(6) screws. Finally, reconnect all external cables.
