2.7.3.1 Activating Power over Ethernet
The Ethernet interfaces ETH1, ETH2, ETH3 and ETH4 on the front panel support Power
over Ethernet.
The
smb2_poe tool included in the Windows ERTC/SMB Support Package (13Y021-70)
gives access to the POE interfaces.
The interfaces can be activated using the following command:
The interfaces can be deactivated using the following command:
2.7.4 Managing RTC Time Adjustments
During the boot process, the CPU firmware gets the time from the system RTC (ERTC)
and sets the CRTC accordingly. In the next step, the operating system (OS) gets the time
from the CRTC and sets the system time accordingly. Now the OS system time is updated
independently of the CRTC via periodic clock interrupts. Thus, over time (i.e. as the
system runs), the system time may become out of sync with the CRTC/ERTC time.
If the system time is adjusted (e.g. by the user), the ERTC time will not be automatically
adjusted by the time management, because the OS is not aware of the additional ERTC.
The ERTC time will not be updated and is out of date. During the next system boot, the
OS would use the outdated time.
MEN provides a dedicated ERTC driver to manage system time adjustments.
2.7.5 Configuring Wireless Functions
You can configure the following by accessing a configuration register (
0x42
) on the
SMBus:
 Enable/disable power for a wireless interface card

Switch SIM card allocation to wireless interface cards
The smb2_ctrl tool included in the Windows ERTC/SMB Support Package (13Y021-70)
See the MEN website for the driver download:

The interfaces are deactivated by default and have to be activated after
every booting of the system.
