Microsemi VSC7428 Managed Ethernet Switch and CEServices
The core component of the LAN35Mx08 is the Microsemi VSC7428 Managed Ethernet Switch (formerly Vitesse) and its corresponding
CEServices Carrier Ethernet switching software. It is an industrial temperature rated, 10 port Gigabit Ethernet switch. The switch features an
integrated MIPS32 processor, DDR2 RAM, and a SPI Flash device to run CEServices. CEServices is built on top of the open source eCos
operating system and Redboot boot loader.
Initial configuration of CEServices should be done via the USB Serial Console using the Industrial Command Line Interface (ICLI). Once the
switch has basic configuration settings (IP address, subnet mask, admin password, etc), it may be managed via the network. Network
management is possible via ICLI (SSH/Telnet), or a GUI interface with a web browser (HTTP/HTTPS), or programmatically via JSON or SNMP.
It is up to the user to determine the correct IP address for their network. Note that once an IP address is assigned to the VSC7428, it may be
accessed by any client on the network unless appropriate security precautions are taken (setting a password, only allowing encrypted
management protocols, etc). Implementing proper network security is the customer’s responsibility.

Intel I210 Gigabit Ethernet Controller (LAN35MH08HR only)
The LAN35MH08HR has an onboard Gigabit Ethernet controller, the Intel I210. This allows a direct Ethernet connection to a PCIe/104
compatible CPU in the stack without the need for an external cable between the boards. Since the Intel I210 is a PCI Express x1 device, it
should be detected automatically by the CPU
To use the I210, the appropriate networking drivers must be loaded in your Operating System. The I210 is a common Ethernet controller, so it
is supported by many OSes. RTD distributes the Intel PRO Ethernet drivers for Windows 7 and later. For Linux, support is built into kernel 3.5
or later using the
igb
driver. For other operating systems, check with the operating system vendor.
Once the device is detected and networking drivers are loaded in the Operating System, the I210 should appear as an additional Ethernet
interface. This interface is independent of the onboard Ethernet port(s) of the CPU. To communicate on the network, the I210 interface must
be configured with basic network settings such as IP address, subnet mask, and default gateway. It is up to the user to determine the correct
IP addressing scheme for their network.
