3 MAINTENANCE
3.1 INTRODUCTION
The following section outlines the fault-finding procedure for the OSD2144A 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 Ethernet cables are connected to the modem correctly and that the distant
OSD2144A modem has been connected correctly to any external equipment.
▲
Inspect the optical connectors (for fiber SFP option) for any contamination and clean using
isopropyl alcohol and a lint free tissue if any contamination is detected.
