2.3
Installing Optional Redundant Power Supply
Module
The standard Multichannel Media Converter is shipped with one MAIN
Power Supply Module installed at the back of the Multichannel Media
Converter cabinet and with a protective plate covering an installation slot
intended for a second, optional BACKUP Power Supply Module.
NOTE: Prior to installation of the optional redundant Power Supply
Module, a jumper setting on the Management Module already installed in
the Multichannel Media Converter must be changed from the NORMAL
position to the B(a)CK(u)P position.
WARNING: DO NOT CONNECT POWER SUPPLY MODULE TO
EXTERNAL POWER BEFORE INSTALLING IN MULTICHANNEL MEDIA
CONVERTER. FAILURE TO OBSERVE THIS WARNING COULD RESULT
IN EQUIPMENT DAMAGE AND/OR PERSONAL INJURY OR DEATH.
CAUTION: Wear a grounding device and observe electrostatic discharge
precautions when setting Management Module jumper and when
installing Power Supply Module in Multichannel Media Converter.
Failure to observe this caution could result in damage to, and subsequent
failure of, Management Module and/or Power Supply Module.
NOTE: Power Supply Modules can be “hot swapped”.
2.3.1
Setting Management Module Jumper
CAUTION: Failure to set the Management Module NJP1 jumper
correctly may result in false alarms (if the jumper is set to BCKP while
only one Power Supply Module is installed) or in failure to monitor the
redundant power supply (if a second Power Supply Module is installed
and the jumper is left in the NORMAL position).
To set the Management Module jumper:
1.
Place the Multichannel Media Converter on a clean, stable
surface.
2.
Locate the Management Module installed at the back left of the
Multichannel Media Converter.
3.
Carefully remove the Management Module from the Multichannel
Media Converter by unscrewing two (2) thumbscrews that secure
the Management Module to the Multichannel Media Converter
and then gently sliding the Management Module from the
Multichannel Media Converter.
4.
Place the Management Module on flat, stable surface and locate
the jumper identified as NJP1.
5.
Using a small needle-nosed pliers or similar device, change the
2-position jumper labelled NJP1 from the NORMAL position to
the BACKUP position (indicated on Management Module circuit
board).
