Installation of Expansion Cards

Notes about the Cards
The Rack PC is designed for the use with cards as per the AT/PCI specification.
The dimensions of the cards may not exceed the stated
dimensions. If the height is exceeded, contact problems, malfunctions and
difficulties with the assembly cannot be excluded. The illustrations show cards with
a full AT/PCI overall length. Depending on the slot, there may be restrictions on the
overall length.

Note about Long PCI Cards
Before long PCI cards can be inserted into the guides of the fan trough, they must
be fitted with a so-called extender (this should form part of the scope of supply of
long PCI boards). Long PCI cards can be inserted into the guides of ISA modules
by means of this extender.
