LAN35MH08HR & LAN35ME08HR User’s Manual
Note the I210 is separate device from the VSC7428 switch, with its own IP address. They must not be configured with the same IP address.
However, to manage the VSC7428 from the I210 Ethernet port, they should generally be configured for the same subnet (e.g. 192.168.0.5 and
192.168.0.6).

Onboard Status LEDs and External LED pins
The LAN35Mx08 provides a set of onboard multi-color LEDs to indicate status of the switch and the individual Ethernet links.
Ethernet Ports 1-8, the StackNET port(s), and the Host Ethernet Link each include an LED to indicate link status, speed, and activity. The
colors are as follows:
LED Color
Description
Off
No Link
Green
Link at 1000 Mbps, flash with activity
Blue
Link at 100/10 Mbps, flash with activity
Table 21: Link Status LEDs
The Switch Status LED indicates the status of the switch management software. The colors are as follows:
LED Color
Description
Off
No Power
Flashing Green
Redboot Boot Loader
(Takes approximately 10 seconds to boot.)
Solid Green
CEServices has booted
(Switch is operating normally.)
Red
Error Condition
(Check log for details.)
Table 22: Switch Status LED
In addition to the onboard LEDs, the LAN35Mx08 also provides Link/Activity LED signals as discrete pins on CN26 so they may be wired to a
custom enclosure. Refer to the Board Connections chapter for wiring details. Note that for IDAN versions of this product, the external LED
signals are not brought to the outside of the frame.

USB Serial Console
The USB Serial Console connector is primarily used for initial configuration and troubleshooting o
f the managed switch. It is a USB “device
mode” port, with an Exar
XR21B1411IL16 USB UART interface. The USB Serial Console may be connected to a USB port on an RTD
cpuModule, laptop, or a desktop PC.
Modern versions of Windows include drivers for the USB UART. For older versions of Windows, a driver is provided by RTD. Once USB is
connected and the drivers are loaded, the console interface will appear as a serial COM port in the PC’s operating system (e.
g. COM5). The
COM port number can vary depending on how ports were enumerated by the operating system, so it is difficult to predict. The easiest way to
determine the COM port number is to connect the console, load the drivers, and then check the Device Manager (Start > Run >
C:\Windows\System32\devmgmt.msc) once it is installed. Note that when working with multiple LAN35Mx08 boards, each one may be
assigned a different COM port number.

Accessing the USB Serial Console port requires terminal emulation software such as PuTTY, TeraTerm, HyperTerminal, or similar. After
installing the software on the PC, configure the serial connection as follows:
•
Baud Rate = 9600
•
Data Bits = 8
•
Parity = None
•
Stop Bits = 1
•
Flow Control = None
