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-825 User Manual 2
1.1 Introduction
The ASMB-825 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 Scal-
able series processor and DDR4 ECC-REG 2133/2400/2666 MHz memory up to 192
GB. ASMB-825 provides four PCIe x16 slots and two PCIe x8 slots in Gen3.0 high
speed. In addition, the ASMB-825 full SKU has dual Gigabit and dual 10GbE Ether-
net LAN ports that eliminate network bottlenecks.
Two RJ-45 LAN jacks (one is GbE and the other one is 10GbE) can be shared with
IPMI function that allows remote control management. High reliability and outstand-
ing performance makes ASMB-825 the ideal platform for industrial server/networking
applications.
By using the Intel C621/C622 chipset, the ASMB-825 offers a variety of features such
as 6 x USB3.0 and 5 x USB 2.0 connectivity, 8 x onboard SATA III and 1 x M.2 (SATA
and PCIe) interface. It supports software RAID 0, 1, 10 and 5 (Windows only*), and
with the latest Intel RSTe (Rapid Storage Technology Enterprise) it provides compel-
ling RAID solution for NVMe SSDs via Intel VROC (Virtual RAID on CPU) HW key.
These powerful I/O capabilities ensure even more reliable data storage capabilities
and high-speed I/O peripheral connectivity.
1.2 Features
General
Intel Xeon Processor Scalable Family support: ASMB-825 is equipped with
two CPU sockets to support Intel Xeon Platinum/Gold/Silver/Bronze series up to
28-core processors.
High performance I/O capability: 2 x 10GbE + 2 x GbE LAN, 4 x PCIe x16 slot
(x16 link) + 2 x PCIe x8 slot (x8 link), 8 x SATA and 1 x M.2 connector, 6 x USB
3.0 and 5 x USB 2.0 (incl. 1 x Type-A) ports.
Standard ATX form factor with industrial features: ASMB-825 provides
industrial features like long product lifecycle, reliable operation under wide tem-
perature range, watchdog timer, etc.
IPMI 2.0 support: ASMB-825 (T2 and I SKUs) 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-
825 (T2 and I SKUs) through your own computer.
Note! 1. IPMI module will be included in ASMB-825I and ASMB-825T2
SKUs. Only ASMB-825T2 SKU can support 10GbE LAN ports.
2. Please refer to Order Information at the front for chipset, IPMI, and
LAN support on individual product SKU.
3. Please refer to the release note of each Linux OS for Intel's C621/
C622 chipset SATA RAID function support.
