Check that the green LED on the 230Vac power supply module (when equipped) is ON (

ref. 60

, ILL

DCS OFF-AIR REPEATERS, sheet 2).

Check LEDs status on the 48Vdc power supply module: FIGURE 5 and Table 4 show LEDs status on
the power supply module (DC/DC converter) under normal operating conditions.
