2Hardware Platform R1.1, July 2021
2 Hardware Platform
2.1 Introduction
The 4-slot SCHROFF MicroTCA System is designed to accommodate two double Mid-size AMC
modules with RTM and 2 Single Mid-size AMCs for maximum computing power in minimal
space.
The integrated eMCH (Embedded MicroTCA Carrier Hub), power supply and cooling unit
allow easy servicing.
The SCHROFF MTCA.4 1U System contains power and cooling management mechanisms to
ensure a high degree of reliability.
The system components are linked directly to the existing network infrastructure using an
1 GbE switch connected to an 1 GbE uplink.
The System allows the integration of an optional 3rd party eCLK module that routes external
clock and trigger signals to the AMC slots.
Features:
• Shielded steel case
• 2 AMC Double Mid-size slots with RTM slots
• 2 AMC Single Mid-size slots
• MicroTCA Backplane
• EMCH (Embedded MicroTCA Carrier Hub) with GbE uplink and USB
• Power management controller on the backplane
• Built-in fan unit with MTCA Cooling Unit Management
• Side-to-side cooling with air filter
• Integrated 400 W AC Power Supply with wide range AC input and 12 V DC output.
• AC mains/line module with IEC 60320-C14 connector, integrated mains/line fuses and
mains switch
• 1 U height, 19” width, 373 mm depth
• Fat pipe /extended fat pipe lanes prepared for 40 GbE and PCIe Gen3
Note: To achive a maximum height of 1 U, the card cage is installed rotated by 180°. 
This must be considered when installing the AMC modules!

The system provides a replaceable air filter. The air filter can be pulled out after removing the top
cover. The filter meets the requirements of the Telcordia Technologies Generic Requirements GR-78-
CORE specification.
4.3 Cooling
The MicroTCA Shelf is equipped with seven 12 VDC fans for cooling the AMC modules and the power
supply. The fans are controlled as a group by the EMCH.

4.4 Power Supply
The system has a 400 W open frame AC power supply with wide range AC input and 12 VDC output.
The DC output is connected directly to the power management circuitry on the backplane.
The power input is provided by an AC mains/line module with IEC 60320-C14 connector, integrated
mains/line fuses, line filter and a mains/line switch.
Fuse value is T6.3AH250V.

Hazardous voltage!
Parts of the power supply may be exposed with hazardous voltage. 
Always remove mains/line connector before carry out any assembly work.
Caution!
The unit is designed in accordance with protection class 1! It must therefore be operated with protec-
tive earth/GND connection. Use only a three conductor AC power cable with a protective earth 
conductor that meets the IEC safety standards!
Caution!
There is a ground terminal at the right side. This ground terminal is only for equipotential bonding.
Grounding is achieved through the protective earth conductor of the power cable!

10 eMCH (embedded MicroTCA Carrier Hub) R1.1, July 2021
5 eMCH (embedded MicroTCA Carrier Hub)
The eMCH (embedded MicroTCA Carrier Hub) is intended to provide basic MicroTCA
functionality for switching and managing AMC (Advanced Mezzanine Card) modules.
It delivers switching and hub functionality for the system fabric gigabit ethernet (GbE) as
defined in the AMC.0 standard series.
Furthermore it supports the typical hot swap management and its transition state machine
(M0 to M6) for each AMC module. In addition to that, the embedded MCH monitors and
verifies local sensor data of the chassis and installed FRU devices and supplies MicroTCA
power and cooling concepts by accessing the chassis integrated power supply and fan
coolers.
Remote administration can be done locally over the CLI (Command Line Interface) served by
the front USB port.

The eMCH front panel consists of 4 status LEDs for the AMCs, and 2 LEDs (OK, FAIL) for the
system’s operation status. In addition to the LEDs, you can find sockets for a RJ45 plug and a
micro USB cable.

5.2 Command Line Interface (CLI)
The EMCH is providing a low level command line interface (CLI) which allows to set certain
operational parameters and to display run time information from the MCH and the system.
5.2.1 COM-Settings
The CLI can be accessed over the front MicroUSB port. To establish a connection to a host PC,
use a serial terminal program e.g. Terra-Term, HTerm, Putty, e.g.
Configure the COM port settings as followed:
Table 3: COM port settings
If the terminal is opened, press enter to see if the connection is established successfully.
You can now type “help” to see the list of available commands. Press enter to call the
previous command again.
NOTE: Depending on your operating system, you need to download and install the FTDI-chip
driver manually. Drivers can be downloaded at http://www.ftdichip.com/FTDrivers.htm.
Installing the driver automatically by the windows update may take up to a few minutes.

5.3 Setting the fat pipe / extended fatpipe configurations
The 2 different fat pipe / extended fat pipe configurations are set via a PCIe MUX. For the
setting you must open the configuration menue in eMCH.
• Connect your host PC to the USB port and start your terminal program
• Power-up the system (eMCH)
• During the booting process you can see the current configuration
eMCH on platform: NATIVE-R1-MINI
Set PCIexpress MUX: 0x00: OK! - Read back: 0x00
• To change the configuration enter:
cfg
• and go through the settings list by hitting the RETURN button until you reach the topic
“Use alternate PCIexpress configuration“
• Type “y“ and hit RETURN
• Go to the end of the list and save the changes to flash

5.4 Firmware Update
The EMCH serves a web based front end to easily upgrade the devices firmware in field. To
use this utility, first establish an ethernet link over the EMCH uplink port. If not changed, the
standard interface config is as followed:
Table 5: Standard interface configuration
Type http://192.168.1.138/ in your web browser or type “bl” in the command line interface
to call the bootloader. Your browser should show the index page with a button “call
bootloader”. By clicking on this button, a software reset will be triggered and the system will
boot into the bootloader. Wait a few seconds and call http://192.168.1.138/ again. The page
should have changed slightly and will prompt you to enter a password. By default, the
password is “nat”. To leave the bootloader without touching anything, just click on “Leave
Bootloader”.
By clicking on “submint” the upload page should open.
Now select a proper firmware image with the file extension “.srec”. Click upload to flash the
image into the device memory.
NOTE: The upload process will take a few seconds, please don’t interrupt or close the browser
while upgrading.
If succeed, the Message “File Upload Done” is shown. Click on “Reset MCU” to trigger a
software reset. The device should now boot into the new firmware.
NOTE: If something went wrong during the firmware upgrade (e.g. lost of power or
communication during file transfer), the device will boot into the bootloader again instead of
loading the firmware. In this case you can easily repeat the firmware upgrade.
