SmartNode SN1200 Hardware Description
The ports available are tabulated in Table 1-1 below. Each port is labeled above and below the socket
with its interface name and type, as in the Port column of the table.
Port
Description
ETH 0
10BaseT
(Modem)
10BaseT Ethernet RJ-45 socket to connect the SmartNode with an Ethernet
device. This is usually a transmission modem, i.e. cable or DSL modem. ETH 0
is a host port; depending on the pin out of the modem, it can be connected with
a straight wired (1:1) or a crossover cable. The ’LINK’ LED to the left of the
connector is lit when the port is connected correctly to an active Ethernet device.
ETH 1
10BaseT
(LAN)
10BaseT Ethernet RJ-45 socket to connect the SmartNode with an Ethernet
device, usually a LAN hub or switch. ETH 1 is a host port; it can be connected
with a straight wired (1:1) to a hub or a crossover cable to a host (PC) port. The
’LINK’ LED to the left of the connector is lit when the port is connected correctly
to an active Ethernet device.
BRI 0
ISDN T
(Line)
ISDN BRI RJ-45 socket to connect the SmartNode with an ISDN Network
Termination (NT). The interface may be used as a fallback port. The ’L2’ LED to
the left of the connector is lit when the port is connected correctly to an active
ISDN device (Layer 1 is up). The interface is internally terminated at 100 Ohm. It
may be powered by an external power supply to feed TEs connected to BRI 1.
Refer to Appendix A for connection details.
Note:
External S-Bus power supplies must comply with the voltage and current
limits set by ISDN standards, i.e. max. 40VDC and 200mA.
Note:
The ’L2’ LED indication depends on the connected device.
BRI 1
ISDN S
(Phone)
ISDN BRI RJ-45 socket to connect the SmartNode with an ISDN S-Bus, e.g. a
PBX. The ’L2’ LED to the left of the connector is lit when the port is connected
correctly to an active ISDN device (Layer 1 is up). The interface is internally
terminated at 100 Ohm. Note: The ’L2’ LED indication depends on the
connected 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.
Warning:
Do not plug in an ISDN connection. The voltage on the S-Bus may
permanently damage the console interface.
Table 1-1: SmartNode SN1200 Port Description
In addition two other elements the Reset button and power lines socket are available on the rear
panel of a SN1200 as described in Table 1-2 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.
