The modem is held in place with the use of plastic rails known as a "snap trac." To replace a failed 
modem, disconnect all attached cables and carefully "snap" it out of the rails. Insert the new 
modem by first laying one end into the rails of the "snap track," then pivot it up and snap into 
place. 

4.3 Power 

Summary 

The power routing for the display can be summarized as follows: 
 

1. 

Incoming power terminates at the termination block (TB41) within the power termination 
enclosure. Before leaving the enclosure, the power is sent through a fuse and an RFI electrical 
filter. 

 

2. 

Power for the controller board passes through a transformer located on the controller/power panel. 

 

3. 

3VDC power supplies are used to power the modules. Power supplies are pre-set at 3.6 VDC. 

4.4  Service and Diagnostics 

The following sub-sections address servicing of the following display components: 
 

· 

transformer, RFI filter and fuse 

· 

controller 

· 

modules, drivers and power supplies 
 

The sub-sections also address any diagnostic LEDs, fuses and signal/power connectors found on the 
unit.
