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!

8EMCH (Embedded MicroTCA Carrier Hub) R1.0, February 2016
5 EMCH (Embedded MicroTCA Carrier Hub)
The EMCH (Embedded MicroTCA Carrier Hub) is intended to provide basic MicroTCA
functionality for switching and managing two 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.

5.1 Front Panel and LEDs
The EMCH front panel consists of two status LEDs for the AMCs, and each one LED (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 Comand 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 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.
