Plug the FLB 3204 into the Base Unit
5.3.2 Insertion of Multiple FLB 3204
Detection Order
The boot sequence of the base unit includes an automated detection of the inserted extension
cards. This detection is done sequentially, slot per slot starting from left to right (when holding
the base unit with its logo on the right side).
Software Compatibility
The base unit allows the insertion of multiple extension cards, sometimes of the same type.
Some configurations including multiple extension cards, even if mechanically acceptable, are not
supported by the embedded software. Cards in excess are ignored during the automated
detection process which means that the base unit and its running extension cards will operate
normally.
The Flexy firmware currently supports up to 1 FLB 3204.
The ignored card(s) will appear in the Diagnostic > Status > System Info > System but they will
not be functional.
Fig. 8 Order of the Extension Cards
The picture above shows an example of a configuration that would be OK mechanically and
power wise but would not be supported by the firmware.
During the boot process, the first 2 serial port extension cards are detected and both can be used.
In case of 2 single Ethernet cards, these 2 cards are also detected but the second Ethernet card is
not supported by the firmware and cannot be used. The presence of this "ignored" card in the
base unit does not alter the operation of the base unit itself nor does it alter its "accepted"
extension cards.
5.3.3 Power Requirements
The internal power converter of the Flexy base units has been dimensioned to cover a broad
range of different combinations of extension cards. Users should make sure the total power

The "Power Requirements" concept doesn't apply to Flexy 205 and its inserted extension
cards.
