Although the backplane of the OmniBus A18 is based on standard 64bit/66MHz PCI bus it is
highly recommended to not insert other cards than those mentioned above.
Other cards will not work due to the missing driver support and there is also a risk to
damage the OmniBus A18 or the inserted cards.

at the bottom to the right there is the

In an OmniBus A18 with redundant power supply the LED [3] also lights up green, if one of
the two power modules is removed but the remaining power module is working well.
It is not an indicator that redundancy is available!
