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.

Power Requirements
The “Power Requirements” concept doesn’t apply to Flexy 205 and its inserted
extension cards.
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
demand of the extension cards does not exceed the capabilities of the base unit. That is why
the notion of “Energy Points” has been introduced.
The Installation Guide “
eWON Flexy - Base Units
” includes a section giving the
Available
Energy Points
of each type of base unit.
The power requirements of each extension card is expressed in
Energy Demand Points.
This
number is meant to check whether the balance with the
Available Energy Points
of a given
base unit with extension cards is OK or not.
The Energy Demand Points of the FLB 3601 is
