Introduction
The Intel
®
Xeon
®
Processor E3-1125C with Intel
®
Communications Chipset 8910
Development Kit (CRB) hardware design is based on the Intel
®
Xeon
®
and Intel
®
Core™ Processor For Communications Infrastructure connected to the Intel
®
Communications Chipset 89xx Series. The CRB design supports one Intel
®
Xeon
®
and
Intel
®
Core™ Processor For Communications Infrastructure using a device down
topology . The processor supports up to two DDR3 channels and up to 20 PCI
Express* Gen 2 lanes, as shown below.

Reference Board Overview
Unless otherwise stated references to the "CRB" or "customer reference board" refer
to the Intel

Xeon
®
Processor E3-1125C with Intel
®
Communications Chipset 8910
Development Kit. Unless otherwise stated references to the “processor” and "CPU"
throughout this document refer to the Intel
®
Xeon

and Intel
®
Core™ Processor For
Communications Infrastructure. Unless otherwise stated references to the “chipset,”
“Platform Controller Hub,” or “PCH” refer to the Intel
®
Communications Chipset 89xx
Series.
The CRB schematics are the primary source for details about the CRB. This user guide
is a supplement to the schematics. Component reference designators in this user's
guide are based on the CRB schematics and are defined by their type and board-
mapped location. They end with a numerical index. The board-mapped locations are
sectioned on a grid pattern: 1 through 9 horizontally, and A through K vertically. The
bottom side of the board has a similar grid pattern but with different call-outs. See the
grid call-outs along the edges of the board. U6D1, for example, is an IC (U), is on the
top of the board at cross section 6D, and is the first indexed component (1) of that
type in that area.
