Product Warranty (2 years)
Advantech warrants the original purchaser that each of its products will be free from
defects in materials and workmanship for two years from the date of purchase.
This warranty does not apply to any products that have been repaired or altered by
persons other than repair personnel authorized by Advantech, or products that 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
customers never need to use our repair service. If an Advantech product is defective,
it will be repaired or replaced free of charge during the warranty period. For out-of-
warranty repairs, customers will be billed according to the cost of replacement mate-
rials, service time, and freight. Please consult your dealer for more details.
If you believe your product to be defective, follow the steps outlined below.
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 displayed when the prob-
lem 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 a return merchandise authori-
zation (RMA) number from your dealer. This allows us to process your return
more quickly.
4. Carefully pack the defective product, a completed Repair and Replacement
Order Card, and a proof of purchase date (such as a photocopy of your sales
receipt) into a shippable container. Products returned without a proof of pur-
chase date are not eligible for warranty service.
5. Write the RMA number clearly on the outside of the package and ship the pack-
age prepaid to your dealer.

interference to radio communications. However, there is no guarantee that interfer-
ence will not occur in a particular installation. If this equipment does cause harmful
interference to radio or television reception, which can be determined by turning the
equipment off and on, the user is encouraged to try to correct the interference by one
or more of the following measures:
Reorient or relocate the receiving antenna.
Increase the separation between the equipment and receiver.
Connect the equipment into an outlet on a circuit different from that to which the
receiver is connected.
Consult the dealer or an experienced radio/TV technician for assistance.

ASMB-815 User Manual 2
1.1 Introduction
The ASMB-815 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 2133/2400/2666/2933 MHz memory up
to 768 GB.
ASMB-815 provides five PCIe x8 or two PCIe x16 and one PCIe x8, one PCIe x4 and
one PCIe x1 Gen3.0 high speed. In addition, the full ASMB-815 SKU has dual Giga-
bit and dual 10GbE Ethernet LAN ports that eliminate network bottlenecks. (ASMB-
815 I & T2 SKUs only)
The fifth RJ-45 LAN connector (LAN5) is dedicated for IPMI function that allows
remote control management. One RJ-45 LAN jack (LAN3) from 10GbE port can also
be used as IPMI LAN. High reliability and outstanding performance makes ASMB-
815 the ideal platform for industrial server/networking applications.
By using the Intel C621/C622 chipset, the ASMB-815 offers a variety of features such
as 6 x USB3.0 and 7 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 a com-
pelling 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-815 is equipped with
single CPU socket 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, 2 PCIe x16 slot
(x8 or x16 link) +3 PCIe x8 slot (x8 link) +1 PCIe x4 (x4 link) + 1 PCIe x1 (x1
link), 8 x SATA and 1 x M.2 connector, 6 x USB 3.0 and 7 x USB 2.0 (incl. 1 x
Type-A) ports.
Standard ATX form factor with industrial features: ASMB-815 provides
industrial features like long product life cycle, reliable operation under wide tem-
perature range, watchdog timer, etc.
IPMI 2.0 support: ASMB-815 (T2 and I SKUs) equipped with ASPEED 2500
BMC chip supports IPMI 2.0 (Intelligent Platform Management Interface 2.0) via
dedicated LAN port.
KVM over IP: KVM over IP function allows BIOS level remote control of ASMB-
815 (T2 and I SKUs) through your own computer.
Note! 1. IPMI module will be included in ASMB-815I and ASMB-815T2
SKUs. Only ASMB-815T2 SKU can support 10GbE LAN ports.
2. Please refer to Ordering Information at the front for chipset, IPMI,
and LAN support on individual product SKUs.
3. Please refer to the release note of each Linux OS for Intel's C621/
C622 chipset SATA RAID function support.

9 ASMB-815 User Manual
Chapter 1 Overview
1.6 System Memory
ASMB-815 has six 288-pin memory slots for DDR4 2133/2400/2666/2933 MHz mem-
ory modules with maximum capacity of 768GB (Maximum 128GB for each DIMM).
ASMB-815 supports registered DIMMs memory module.
1.7 Memory Installation
Memory performance is affected by different DIMM configurations. To reach optimal
memory interleaving, be sure to install identical DIMM types with the same size,
speed, and number of ranks on those memory slots corresponding to the correct pro-
cessor.
The following table indicates recommended DIMM configurations with a single pro-
cessor, based on the guideline, you may adjust your memory configuration according
to your PCIe expansion card configuration.
2nd Gen Xeon Scalable (82xx/62xx/52xx/4215) processors support Optane DC per-
sistent memory module (DCPMM).
AD: App Direct Mode; MM: Memory Mode; AD+MM: Mixed Mode.
DRAM1: RDIMM, 3DS RDIMM, LRDIMM, 3DS LRDIMM
DRAM2: RDIMM
DRAM3: RDIMM; 3DS RDIMM; LRDIMM
Any capacity of DCPMM is allowed

1.8 Processor Installation
The ASMB-815 is designed for the Intel Xeon processor family.
1. Remove dust cover.
(The following pictures are referred from same platform ASMB-825 with dual proces-
sors but ASMB-815 is with single processor)
2. Install CPU on CPU clip and align the pin 1 mark.

11 ASMB-815 User Manual
Chapter 1 Overview
3. Install the CPU clip assembly on the heatsink as a processor + heatsink module.
4. Place the processor heatsink module into the motherboard bolster plate by
using a T-30 screw driver (follow heatsink label direction 1-2-3-4).
