3 MAINTENANCE
3.1
INTRODUCTION
The following section outlines the fault-finding procedure for the OSD2155 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 PSE power
requirements do not exceed the OSD2155 modems maximum PD power.
▲
Inspect the optical connectors (fiber SFP) for any contamination and clean using isopropyl alcohol
and a lint free tissue if any contamination is detected.
3.3
ROUTINE MAINTENANCE
