Notes on the modules

Notes on module specifications
The device is designed for use with modules conforming to ATX-/PCI-/PCIe specifications.
The dimensions of the cards may not exceed the specified dimensions. If the height is
exceeded, you may experience contact problems, malfunctions and difficulties with the
assembly. The permitted dimensions of the modules are found in the dimensional drawings
section.
Notice
The performance is limited for PCI modules with 5V supply voltage. The output of the
modules may not exceed 25W in total.
Note about long PCI, PCIe modules
Before long modules can be inserted into the guide rails, they must be fitted with an extender
(this should form part of the scope of supply of long modules).
Notes on the allocation of resources
Due to the number of functions on the motherboard, there are no reserved interrupts for PCI
modules. If the new expansion module requires exclusive resources, you have to disable the
functions on the motherboard. You will find notes on the allocated resources in the
motherboard technical manual D2156-S on the supplied "Documentation and Drivers" CD.
