replacement transceiver will use the CIM script on the SD memory card and its configuration will be the same as
the original transceiver.

RECEPTION PROBLEMS

Problem indicators

A transceiver in the network stops receiving communications from another transceiver.

The RX LED is off.

To troubleshoot receiver issues:

1.

Make sure the transceiver is turned on and the PWR LED illuminates and blinks.

2.

Verify the transmit frequency is within limits. See

Operational Characteristics

.

3.

Verify the antenna cable connectors are securely connected to the antenna and the transceiver.

4.

Verify each antenna is connected to the appropriate antenna input connector at the rear of the unit and terminate
unused connectors. (See

APPENDIX B— Possible RF Antenna Configurations

for more specific information, if

necessary.)

5.

Check the cable connector and transceiver connector for corrosion.

6.

Replace the cable or connector.

7.

Check the antenna for any defects or breaks.

8.

Replace the transceiver. When replacing a transceiver, if the SD card contains a valid CIM script, remove the SD
memory card from the nonworking transceiver and insert and seat it in the replacement transceiver. The
replacement transceiver will use the CIM script on the SD memory card and its configuration will be the same as
the original transceiver.

7.7

ETHERNET CONNECTIVITY PROBLEMS

Problem indicators:

The transceiver is disconnected from the Ethernet network.

The DTE Link LED is off.

To troubleshoot network connectivity issues:

If you cannot directly connect to the MAINT port on the transceiver, then contact your system administrator.

1.

Check network activity, for example, by using Wireshark software (or equivalent) and a computer. If the network is
down, persons responsible for the network administration will need to restore network operation.

2.

Make sure the Ethernet cable is securely connected to the transceiver LAN port.

3.

Verify external network equipment is functioning properly.
