3 MAINTENANCE
3.1
INTRODUCTION
The following section outlines the fault-finding procedure for the OSD8327T and OSD8327R modems.
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 Electrostatic (ES) sensitive and Electrostatic Discharge
(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 is connected to the power socket.
▲
Check that the HD/SDI and data signals are connected to the modem correctly and that the distant
▲
OSD8327T or OSD8327R 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.
3.3
ROUTINE MAINTENANCE
