BL50S - Box PC for Storage Applications (AMD)
The BL50S is a maintenance-free box computer that has been designed for storage
applications such as content servers or video recorders. It offers two external SATA
shuttles with hot-plugging support.
On the front of the BL50S as many as 5 Gigabit Ethernet interfaces are accessible.
Four of these ports share one Gigabit Ethernet port from the chipset via a switch,
while one port is used exclusively as Gigabit Ethernet uplink. The four ports routed
over the switch support Power-over-Ethernet.
One PCI Express Mini Card slot with two SIM card slots offers the possibility to
implement the wide range of functionality available on this form factor. This
includes for example mobile service standards GSM (2G), UMTS (3G), LTE (4G)
and derivates, wireless communication standards WLAN / Wi-Fi IEEE 802.11 and
derivates as well as positioning systems GPS or GLONASS.
The BL50S is powered by an AMD Embedded G-Series APU (Accelerated
Processing Unit), the T48N, running at 1.4 GHz. The G-Series combines low-power
CPUs and advanced GPUs, in this case an AMD Radeon HD 6310, into a single
embedded device. The use of the Embedded G-Series makes for high scalability in
CPU (single/dual core) and graphics performance (various Radeon GPUs or none at
all).
The BL50S is equipped with 2 GB of DDR3 SDRAM and offers SD card and
mSATA slots. The system is designed for fanless operation at temperatures from -40
to +70°C (+85°C for up to 10 minutes), its special aluminum housing with cooling
fins serves as a heatsink for the internal electronics and in this way provides
conduction cooling.
The BL50S supports one DisplayPort interface with a resolution of 2560×1600. In
addition, a multitude of other I/O is available at the front panel, including two USB
2.0 and variable slots for legacy serial I/O (e.g. RS232) or CAN bus.
The BL50S comes with its own integrated class S2 wide-range power supply with
24 and 36 VDC nominal input voltage (10 to 50.4 V) and a power consumption of
30 W and is in compliance with EN 50155 and ISO 7637-2 (E-mark for
automotive). The power can be switched on and off using an ignition signal on the
power connector, and a run-down time after switching off the power can be adjusted
by software.
The combination of the various CPU/GPU options with the available selection of
external interfaces makes for an extremely flexible system design that can quickly
be tailored to a vast number of applications.

20BL50S00 E2 – 2014-12-10
Product Safety
Electrostatic Discharge (ESD)
Computer boards and components contain electrostatic sensitive
devices. Electrostatic discharge (ESD) can damage components. To
protect the board and other components against damage from static
electricity, you should follow some precautions whenever you work on
your computer.
• Power down and unplug your computer system when working on the
inside.
• Hold components by the edges and try not to touch the IC chips,
leads, or circuitry.
• Use a grounded wrist strap before handling computer components.
• Place components on a grounded antistatic pad or on the bag that
came with the component whenever the components are separated
from the system.
• Only store the board in its original ESD-protected packaging. Retain
the original packaging in case you need to return the board to MEN
for repair.

Conditions for Use, Field of Application
The correct function of MEN products in mission-critical and life-critical applications is limited to the
environmental specification given for each product in the technical user manual. The correct function of MEN
products under extended environmental conditions is limited to the individual requirement specification and
subsequent validation documents for each product for the applicable use case and has to be agreed upon in writing
by MEN and the customer. Should the customer purchase or use MEN products for any unintended or
unauthorized application, the customer shall indemnify and hold MEN and its officers, employees, subsidiaries,
affiliates, and distributors harmless against all claims, costs, damages, and expenses, and reasonable attorney fees
arising out of, directly or indirectly, any claim or personal injury or death associated with such unintended or
unauthorized use, even if such claim alleges that MEN was negligent regarding the design or manufacture of the

RoHS
Since July 1, 2006 all MEN standard products comply with RoHS legislation.
Since January 2005 the SMD and manual soldering processes at MEN have already been completely lead-free.
Between June 2004 and June 30, 2006 MEN’s selected component suppliers have changed delivery to RoHS-
compliant parts. During this period any change and status was traceable through the MEN ERP system and the
boards gradually became RoHS-compliant.
WEEE Application
The WEEE directive does not apply to fixed industrial plants and tools. The compliance is the responsibility of the
company which puts the product on the market, as defined in the directive; components and sub-assemblies are
not subject to product compliance.
In other words: Since MEN does not deliver ready-made products to end users, the WEEE directive is not
applicable for MEN. Users are nevertheless recommended to properly recycle all electronic boards which have
passed their life cycle.
Nevertheless, MEN is registered as a manufacturer in Germany. The registration number can be provided on
request.
