Port
Description
SERIAL 0/0
(V.35 / X.21)
DB25 socket providing a V.35 and X.21 interface for Leased Lines up to
2Mbit/s. A LED to the left of the connector indicates its status.
ETH 0/1
(10BaseT)
10BaseT Ethernet RJ-45 socket to connect the SmartNode with an Ethernet
device, such as a wide area transmission modem, Ethernet hub or switch.
ETH 0/1 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.
ETH 0/0
(10 / 100BaseT)
10 / 100BaseT Ethernet RJ-45 socket. The interface has similar functionality to
ETH 0/1 except for the option of 100BaseT capability. The ’100Mb/s’ LED is
lit when the port is connected correctly to an active 100BaseT Ethernet
device.
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.
Table 3-1: SmartNode SN2300 Port Description
In addition two other elements the Reset button and power lines socket are available on the rear
panel of a SN2300 as described in Table 3-2 below.
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.
100 - 240VAC
50/60 Hz
Electricity supply socket for mains power cable.
