Safety Instructions
Integrated circuits on computer boards are sensitive to static electricity. To
avoid damaging chips from electrostatic discharge, observe the following
precautions:
Do not remove boards or integrated circuits from their anti-static packaging
until you are ready to install them.
Before handling a board or integrated circuit, touch an unpainted portion of
the system unit chassis for a few seconds. This helps to discharge any static
electricity on your body.
Wear a wrist-grounding strap, available from most electronic component
stores, when handling boards and components. Fasten the ALLIGATOR clip
of the strap to the end of the shielded wire lead from a grounded object.
Please wear and connect the strap before handle the HS-2621 to ensure
harmlessly discharge any static electricity through the strap.
Please use an anti-static pad when putting down any components or parts or
tools outside the computer. You may also use an anti-static bag instead of
the pad. Please inquire from your local supplier for additional assistance in
finding the necessary anti-static gadgets.
NOTE: DO NOT TOUCH THE BOARD OR ANY OTHER SENSITIVE
COMPONENTS WITHOUT ALL NECESSARY ANTI-STATIC
PROTECTIONS.

Chapter 1
General Description
The HS-2621 is an Intel® 945GSE/ICH7-M chipset-based board
designed, the board supports Intel® Atom™ N270 processor 1.6GHz.
The HS-2621 is an ideal all-in-one embedded engine board. Additional
features include an enhanced I/O with CF, DVI-D/CRT/LVDS, Gigabit
Ethernet, audio, SATA, 4 COM, USB2.0, and PCI-104 interfaces.
The Intel® 945GSE integrated Intel® GMA950 with 244MB shared
main memory supports CRT/Panel displays up to 2048 x 1536. It also
supports the LVDS interface of 18-bit single/dual-channel.
System memory is also sufficient with the one 200-pin SO-DIMM
socket up to 2GB DDR2 SDRAM.

2
Additional onboard connectors include an advanced USB2.0 port
providing faster data transmission. And one RJ-45 connector for
Gigabit Ethernet uses. To ensure the reliability in an unmanned or
standalone system, the watchdog timer (WDT) onboard HS-2621 is
designed with software that does not need the arithmetical functions of
a real-time clock chip. If any program causes unexpected halts to the
system, the onboard WDT will automatically reset the CPU or generate
an interrupt to resolve such condition.

Unpacking
2.1 Opening the Delivery Package
The HS-2621 is packed in an anti-static bag. The board has
components that are easily damaged by static electricity. Do not
remove the anti-static wrapping until proper precautions have been
taken. Safety Instructions in front of this manual describe anti-static
precautions and procedures.
2.2 Inspection
After unpacking the board, place it on a raised surface and carefully
inspect the board for any damage that might have occurred during
shipment. Ground the board and exercise extreme care to prevent
damage to the board from static electricity.
Integrated circuits will sometimes come out of their sockets during
shipment. Examine all integrated circuits, particularly the BIOS,
processor, memory modules, ROM-Disk, and keyboard controller chip
to ensure that they are firmly seated. The HS-2621 delivery package
contains the following items:
HS-2621 Board x 1
Utility CD Disk x 1, including User’s Manual
Cables (as following table)
Jumper Bag x 1
