Appendix D – Adding or Replacing Boards
This appendix covers the procedure to add or replace a Modula input or output board.
Input and output boards can be added to a partially filled enclosure to expand a system's capabilities or
increase an enclosure's possible signal routings.
A VIS board can also be added to a Modula enclosure to synchronize video signal switches with the
output device's refresh rate. A VIS board must be enabled after installation by updating the system's
configuration file. (For information, see "Appendix E – Vertical Interval Sync" on page 177.)
Other types of boards may or may not require an update to the system configuration. See "Configuration
Requirements" below to determine if the system's configuration information needs to be updated after
adding or replacing an input or output board.
Important: Adding or replacing boards should only be done by personnel trained to handle ESD
sensitive parts and assemblies.
Items Required
Configuration Requirements
Before starting:
ESD Warning: To avoid ESD (Electrostatic Discharge) damage to sensitive components, make sure
you are properly grounded before touching any internal Modula materials. Use an ESD wristband
and cord with alligator clip attached to a good ground source.
Modula Instruction Manual
Modula board(s)
Phillips #1 screwdriver
ESD wristband and cord with alligator clip
Updated configuration file (see "Configuration Requirements" below to determine if required)
If a board is replaced with the same type of board or if the system was configured for
expansion, the configuration file will not need to be updated.
If a board is added to a previously empty slot as part of an unplanned upgrade or if a board is
replacing a different type of board, a CD has been included with an updated configuration file,
which must be uploaded to the system (see page 174) for the new board to work.
Turn off the power switch on the rear of the enclosure and unplug the power cord.
Multiple-enclosure systems – label and disconnect link cables.
If necessary – label and disconnect all cables on the board being replaced. If cables from
adjoining boards obstruct access, label and disconnect them as necessary.
