NTRODUCTION
It is important to be aware of the system considerations listed below before installing your ATXN-5520
(S6900-xxx) motherboard. Overall system performance may be affected by incorrect usage of these
features.

NSTALLATION
Chassis Plans‟ ATXN-5520 /ATXW-5520Extended ATX motherboards comply with the SSI-EEB
Enterprise Bay Specification 2008, Revision 1.0. This specification defines the Extended ATX
motherboard form factor including the board‟s mechanical dimensions, mounting hole locations, option
card slot locations, I/O connector placements, maximum component heights and the motherboard‟s I/O
plate dimensions.
Note: The I/O plate for the motherboard is packed with the motherboard inside its own separate bag. The
I/O plate needs to be installed into the standard chassis opening to cover the gaps between the
motherboard‟s I/O connectors and ensure ESD protection.
Chassis that adhere to the SSI-EEB industry standard should be used with the ATXN-5520 motherboard.
See the ATXN-5520/ATXW-5520dimension diagram in the
Chapter 1 - Specifications
for more details.
12V AUX P

EQUIREMENTS
Both 12V AUX motherboard connectors (P15 and P16) must be connected to the system power supply to
ensure proper board operation.
DDR3 M
EMORY
The DDR3 memory modules used in the ATXN-5520 must be ECC registered (72-bit) DDR3 DIMMs and
must be PC3-10600, PC3-8500 or PC3-6400 compliant.
NOTES:
 All memory modules must have gold contacts.
 Low voltage (DDR3L) DIMMs are not supported.
 To maximize memory interface speed, populate each memory channel with DDR3
DIMMs having the same interface speed.
 Populate the memory channels starting with the DIMM socket farthest from the CPU.
Work you way toward the processor populating the DIMM sockets labeled with an “A”
first followed by the “B” labeled sockets.
 If populating a memory channel with a Quad-rank and a Single- or Dual-rank DIMM
place the Quad-rank DIMM farthest from the processor.
The motherboard will support DIMMs with different speeds, but the memory channel interface will operate
at the speed of the slowest DIMM.
SATA RAID O
PERATION
The ICH10R I/O Controller Hub used on the motherboard features Intel
®
Matrix Storage Technology,
which allows the ICH10R‟s SATA controller to be configured as a RAID controller supporting RAID 0, 1,
5 and 10 implementations. To configure the SATA ports as RAID drives or to use advanced features of the
