Introduction
This guide describes how to mount and install the ITI-2135 and ITI-2147 PCI
Bridged Riser Cards in your system.
Organization of this Guide

Installing the Riser Card
Overview of the Riser Cards
The ITI-2135 and ITI-2147 Bridged Riser Cards provide a method of turning a
PCI slot 90
o
to enable a low profile 2U system to use standard height PCI cards.
The Riser provides three full function PCI slots. IntraServer Bridged Riser
Cards provide a PCI to PCI bridge chip that isolates the three additional slots
from the host PCI bus. Non-bridged riser cards can present unacceptable PCI
bus loading due to long stubs.
The IntraServer Riser Cards will operate in any PCI slot, 32 or 64 bit, 33 MHz
or 66 MHz, 3.3V or 5V signaling. The ITI-2135 and ITI-2147 are functionally
identical, but dimensionally the ITI-2147 is 0.3" shorter than the ITI-2135. See
Table 5 for the dimensional specifications of each card.
