Function Boards
These Function Boards are Euro-boards that were designed for integration in 19" Systems.
All boards are connected to the System via a VG ledge (DIN41612). The boards receive their
power supply and the required data or signals via these VG ledges.
The front panels of the Boards are designed as standard for 3U/19" Systems or they can be
used with an adapted panel on the 1U Slim Line System.
Basically this Function Board is available in two types:
Function Boards for System-Bus
These Boards can only operate on a System-Bus. However, account must be taken
of board-specific restrictions.
Function Boards
These Boards can operate with or without a System-Bus.
There are some points that must be considered when dealing with Function Boards:
Electrical Properties
The System and Function Boards do
not
support
hot plug
capability.
If it is necessary to exchange a board the System
must
be switched off first.
Otherwise the System or Function Board could be damaged.
Power Supply
All Function Boards are powered by the operating voltage via the internal System-Bus or via
system internal connections.
Mechanics
Function Boards with suitable front panels are required for installation in 1U-Systems and
3U-Systems.
Configuration
In principle there are two board types:
Boards which are configured via DIP switches and jumpers only
(the board must be configured prior to installation)
Boards which are configured via the System 6844(RC) menu (and DIP switches or
jumpers), (the base configuration of the board must be set prior to installation; the
other settings are then carried out via the System 6844(RC) menu).
Factory Pre-wired Slots
In addition, some Function Boards require system-internal wiring in order to achieve the de-
sired functionality. Where boards are to be delivered with this wiring integrated into the Sys-
tem the wiring is carried out in the factory.
The details of slots which are wired at the time of delivery can be found in the
System drawing / specifications.
