Troubleshooting
Each module has LEDs, testpoints, and switches along its front edge. The
LEDs indicate the operating condition of the module. Testpoints are used
to check voltages and ground. Switches are used to reset the module.
Testpoint and switch markings are self-explanatory.
Matrix Controller LEDs
The location of the LEDs on the Ethernet/Crosspoint Bus Matrix Controller
is shown in Figure 83. See Table 53 for LED usage.
