Fusing
The power supply module has four replaceable fuses on its circuit
board.
Maintenance personnel must ensure that replacement fuses meet
national and local use code requirements.

2.1.4 Data Buffer Module

The Data Buffer Module has two major functions:
1. Video Distribution: In a multiple-bay system, it distributes
switched video from a bay's Video Input Modules to other bays.
The video signals from these outputs only contain standard video,
without any character information.
2. Data Filtering: It filters incoming system information from the
DATA LINE.
The V2903DB rear panel has 16 video output BNCs for connecting
Video Output Modules in other switching bays. The following
figures illustrate various types of Data Buffer Module rear panels.

2.1.5 Data Buffer Module with Video Loss Detection

The Data Buffer Module with Video Loss Detection also provides
the two functions of a common Data Buffer Module, i.e., Video
Distribution and Data Filtering. What makes it different, however,
is its capability of detecting video signal loss for each camera input.
A single module can detect video loss for up to 256 cameras.
The module must be placed in a matrix switching bay that contains
Video Input Modules, and the bay must be connected to the
highest-numbered monitor output.
