SmartNode SN2400 Hardware Description
Port
Description
ETH 0/0
(10 / 100BaseT)
10/100BaseT Ethernet RJ-45 socket to connect the SmartNode to an Ethernet
device, such as a wide area transmission modem, Ethernet hub or switch.
ETH 0/0 is a host port; it can be connected with a straight wire (1:1) to a hub,
or a crossover cable to a host port.
The ’Link’ LED to the left of the connector is lit when the port is connected
correctly to an active Ethernet device. The ’100Mb/s’ LED, also to the left of
the connector, is lit when the port is connected correctly to an active
100BaseT Ethernet device.
ETH 0/1
(10 / 100BaseT)
same as ETH 0/0
Console
(RS-232)
RS-232 RJ-45 connector to connect the SmartNode with a serial terminal such
as a PC or workstation with a RS-232 interface, with the following settings:
9600 Baud, no parity, 8 Bit, 1 Stop bit, 1 Start bit
The console port is only used for service and maintenance purpose.
Caution:
Do NOT plug in an ISDN connector. The voltage on the S-Bus may
permanently damage the console interface.

Element
Description
Reset button
The button has three different functions:
•
Manual Restart:
During normal operation pressing and releasing the
reset button will cause a system reboot. The application will be restarted
without any change to the existing SW configuration.
•
Restoration:
Pressing and holding the reset button for 5 seconds will
restore the factory configuration and automatically reboot the system.
Caution:
In this case the existing IP SW configuration is lost.
•
Boot loader:
Powering the SmartNode while pressing the reset button
for 5 seconds will cause the factory-fitted boot loader to start in place of
the application. The boot loader uses a minimal set of parameters. In
case the application does not start correctly, the boot loader can be used
as a fallback to download a new software version.
