GE MDS 05-4558A01 manual Troubleshooting Using LEDs

TROUBLESHOOTING

It is best to begin troubleshooting at the Access Point, as the rest of the system depends on it for network synchronization and configuration. If the Access Point has problems, the operation of the entire network will be affected.

All radios in the network must meet these basic requirements:

•Adequate and stable primary power

•An efficient and properly aligned antenna system

•Secure connections (RF, data & power)

•Proper programming of the unit’s operating parameters, espe- cially Frequency Mode Selection, Network Name, and IP Address

•The correct interface between the radio and the connected data equipment (proper cable wiring, data format and timing)

Table 1 provides suggestions for resolving common system difficul- ties using the radio’s LEDs as a guide. Table 2 on Page 13 provides guidance for using the Menu System as a tool.

If problems cannot be resolved using the guidance provided here, review the GE MDS web site’s technical support area for recent soft- ware/firmware updates, general troubleshooting help, and service information. Additional help is available through our Technical Sup- port Department.
