MAINTENANCE
3.1
INTRODUCTION
The following section outlines the fault-finding procedure for the OSD730 modem. Please take note of the
following:
Personnel without appropriate training should not attempt any maintenance except that outlined below.
If further maintenance is attempted you are warned that every care should be taken to ensure that internal
measurements made while the equipment is operational are taken carefully as some components within the
unit are expensive and may be damaged by failure of any portion of their support circuitry.
Some components within the unit are ES sensitive and ESD precautions should be taken when performing
maintenance upon the unit.
3.2
EXTERNAL INSPECTION
Visually check for the following:
Check that the correct power source (voltage and current) is connected to the power socket.
Check that the data signals are connected to the modem correctly and that the distant OSD730 modem has
been terminated correctly to any external equipment.
Inspect the optical connectors for any contamination and clean using isopropyl alcohol and a lint free tissue
if any contamination is detected.
Check that any external termination resistors are connected if the system configuration requires them in.
3.3
ROUTINE MAINTENANCE
There is no routine maintenance required with the OSD730.
