Connect to RJ45 to RS232 Port
For local management, plug in the console cable into RJ45 to RS232 port. The connector wiring
is shown below.
Power Supply
The device is powered from a DC source (-48V DC) where the positive pole is grounded. By
using adequately gauged cable, properly ground the ODU to the best earth ground available.
Similarly, properly ground the IDU to the cabinet.
LED Indicators
When the device is powered on, it performs startup diagnostics. It is necessary to wait for about
30 seconds before the IDU gets into normal operating state after powering up. When the device
starts up, watch the status diodes MSYNC, STAT1, STAT2. You should see only the diode
STAT1 flashing after the device starts up (if the alarms are not configured, the LED may remain
lit permanently).
