Clear CMOS jumper (CMOS1/CMOS2): It is for clearing
the CMOS data. CMOS 1clears CMOS data with real-time
clock (RTC) whereas CMOS2 clears CMOS data only.
To erase the CMOS data:
Turn off the computer and unplug the power cord.
Move the jumper cap from pins 1-2(default) to pins
1.
2-3. Keep the cap on pins 2-3 for about 5-10 seconds,
then move the cap back to pins 1-2.
Plug the power cord and turn on the computer.
2.
Enter BIOS setup to re-enter data. 3.
Serial-ATA Connector (SATA1/SATA2): It is for connecting
a 2.5’’ hard disk to be served as your system’s storage. It
can support SATA II which features Data transfer rates up
to 6.0 Gb/s (600 MB/s). SATA 2 connector also supports
SATA-DOM (the power line of SATA-DOM can be disabled
with a jumper on, see SATA_PW2).

legacy mode using I/O space, and an AHCI mode using
memory space. Software that uses legacy mode will not
have AHCI capabilities.
The AHCI ( Advanced Host Controller Interface) is a
programming interface which defines transactions
between the SATA controller and software and enables
advanced performance and usability with SATA. Platforms
supporting AHCI may take advantage of performance
features such as no master/slave designation for SATA
devices—each device is treated as a master—and
hardware assisted native command queuing. AHCI also
provides usability enhancements such as Hot-Plug.
Use the BIOS menu to configure your hard disk
to be AHCI compatible.

Preparing the Hardware Installation
To access some components and perform certain service
procedures, you must perform the following procedures
first.
WARNING: To reduce the risk of personal injury,
electric shock, or damage to the equipment,
remove the power cord to remove power from
the server. The power switch button does not
completely shut off system power. Portions of the
power supply and some internal circuitry remain
active until power is removed.
Unpower the IMM-L35PS and remove the power cord.
1.
Unscrew the 4 threaded screws from the top cover.2.
Open the cover. 3.
Note:
If the CPU thermal pad breaks apart, use your
hands to reattach the parts and stick them
together.
Installing the System Memory
The motherboard supports DDR3 memory to meet the
higher bandwidth requirements of the latest operating
system and Internet applications. It comes with two
Double Data Rate Three (DDR3) Small Outline Dual Inline
Memory Module (SO-DIMM) socket.
Align the memory module’s cutout with the SO-DIMM
1.
socket’s notch.
Install the SO-DIMM.
2.
Note:
The system can support memory of DDR3 SO-
DIMM up to 16 GB in maximum with 2 SO-DIMM
sockets.
