Product Warranty (2 years)
Advantech warrants to you, the original purchaser, that each of its products will be
free from defects in materials and workmanship for two years from the date of pur-
chase.
This warranty does not apply to any products which have been repaired or altered by
persons other than repair personnel authorized by Advantech, or which have been
subject to misuse, abuse, accident or improper installation. Advantech assumes no
liability under the terms of this warranty as a consequence of such events.
Because of Advantech’s high quality-control standards and rigorous testing, most of
our customers never need to use our repair service. If an Advantech product is defec-
tive, it will be repaired or replaced at no charge during the warranty period. For out-
of-warranty repairs, you will be billed according to the cost of replacement materials,
service time and freight. Please consult your dealer for more details.
If you think you have a defective product, follow these steps:
1. Collect all the information about the problem encountered. (For example, CPU
speed, Advantech products used, other hardware and software used, etc.) Note
anything abnormal and list any onscreen messages you get when the problem
occurs.
2. Call your dealer and describe the problem. Please have your manual, product,
and any helpful information readily available.
3. If your product is diagnosed as defective, obtain an RMA (return merchandise
authorization) number from your dealer. This allows us to process your return
more quickly.
4. Carefully pack the defective product, a fully-completed Repair and Replacement
Order Card and a photocopy proof of purchase date (such as your sales receipt)
in a shippable container. A product returned without proof of the purchase date
is not eligible for warranty service.
5. Write the RMA number visibly on the outside of the package and ship it prepaid
to your dealer.

ASMB-975 User Manual 2
1.1 Introduction
The ASMB-975 serverboard is the most advanced Intel Xeon Processor Scalable
Family series board for server-grade IPC applications that require high-performance
computing power & multi-expansion slots. This serverboard supports Intel Xeon Pro-
cessor Scalable Family series processor and DDR4 2133/2400/2666 MHz memory
up to 384 GB. ASMB-975 provides four PCIe x16, one PCIe x8 and four PCIe x4
slots in Gen3.0 high speed. In addition, the ASMB-975T2 has dual Gigabit and dual
10GbE Ethernet LAN ports that eliminate network bottlenecks. One GbE RJ-45 LAN
and one 10GbE RJ-45 LAN jack are shared with IPMI function that allows remote
control management. High reliability and outstanding performance makes ASMB-975
the ideal platform for industrial server/networking applications.
By using the Intel C622/C621 chipset, the ASMB-975 offers a variety of features such
as 8 x USB3.0 and 3x USB 2.0 connectivity, 12 x onboard SATA III and 2 x M.2
(SATA only) interface. The 12 x SATA ports support software RAID 0, 1, 10 and 5
(Windows only*), and with the latest Intel RSTe (Rapid Storage Technology Enter-
prise) it provides compelling RAID solution for NVMe SSDs via Intel VROC (Virtual
RAID on Chip) HW key.
These powerful I/O capabilities ensure even more reliable data storage capabilities
and high-speed I/O peripheral connectivity.
1.2 Features

x PCIe x16 slot (x16 link) + 1 x PCIe x8 slot (x8 link), 12 x SATA and 2 x M.2
connectors,8 x USB 3.0 and 3 x USB 2.0 (incl. 1 x Type-A) ports.
Outstanding industrial features: ASMB-975 provides industrial features like
long product lifecycle, reliable operation under wide temperature range, watch-
dog timer, etc.
IPMI 2.0 support: ASMB-975I/ASMB-975T2 equipped with ASPEED 2500
BMC chip supports IPMI 2.0 (Intelligent Platform Management Interface 2.0) via
sharing LAN port.
KVM over IP: KVM over IP function allows BIOS level remote control of ASMB-
975I/ASMB-975T2 sku system through your own computer.
Note! 1. IPMI module will be included in ASMB-975I and ASMB-975T2
SKUs.
2. Three USB 2.0 ports (1*Type- A) and eight USB 3.0 ports (4 ports
from on-board 20-pin header)
3. Please refer to the release note of each Linux OS for Intel's C622/
C621 chipset SATA RAID function support.

1.8 Processor Installation
The ASMB-975 is designed for Intel Xeon processor scalable family.
Step 1
Remove dust cover.
Step 2
Install CPU on CPU clip and align pin 1 mark.

ASMB-975 User Manual 12
Step 3
Install the CPU clip assembly on the heatsink as a processor + heatsink module.
Step 4
Put the processor heatsink module into the motherboard bolster plate by using a T-30
screw driver (follow heatsink label direction 1-2-3-4).
