LED Indicators
You can check the basic operation of the transceiver board(s) by
viewing the LED indicators on the front panel. The top row of indicators
shows the status of the "A" transceiver board; the bottom row shows the
status of the "B" transceiver board. On a redundant radio (spare trans-
ceiver board and power supply installed), the references given here
apply to transceiver board A and B equally.
Normally, only the green
ured for redundant operation, one of the yellow
other red LEDs are alarm indicators. If lit, they indicate a potential
problem in the radio system.
Refer to Figure 25, Table 6 on Page
detailed explanation of the LED indicators.
