Chapter 4
Extension Cards
Example of configuration that would be OK
mechanically and power wise but that is not
supported by the firmware.
During the boot process, the first 2 Serial Port
extension cards (1 & 2) are detected and can be
used, then the 2 Single Ethernet Extension (3 & 4)
are also detected.
The second Single Ethernet Card (4) is not
supported by the firmware so that it CANNOT be
used.
The presence of this “ignored” card in the Base
Unit does not alter the operation of the Base Unit
itself and its “accepted” Extension Cards.
4.5. Extension Card Power Requirements
The internal power converter of the eWON Flexy Base units has been thought 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.
4.5.1. Available Energy Points (Base Units)
Each Base Unit type has a certain amount of
Available Energy Points
. The available energy
points depend on the temperature range in which the equipment will actually be used.
Considering the fact very few applications require the equipment to actually work between
50° and 70°C, the available energy points per Base Unit type are specified for both up to
50°C max. and up to 70°C max.:
