SmartNode SN1400 Hardware Description
19
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 with 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 with 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 S/T
ISDN BRI RJ-45 socket to connect the SmartNode with an ISDN device over a
S/T bus, e.g. a PBX or a NT. The interface may be used as fallback if connected to
a NT. 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 pin-out is configurable;
see the document SmartWare Software Configuration Guide. 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 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 maximum.
Note:
The ’L2’ LED indications depend on the connected device.
BRI 1
ISDN S/T
ISDN BRI RJ-45 socket to connect the SmartNode with an ISDN device over a
S/T bus, such as 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 pin out
is configurable; see the document SmartWare Software Configuration Guide.
The interface is internally terminated at 100 Ohm.
Note:
The ’L2’ LED indications depend 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 an 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 connector. The voltage on the S-Bus may
permanently damage the console interface.
Table 2-1: SmartNode SN1400 Port Description
In addition two other elements the Reset button and power lines socket are available on the rear
panel of a SN1400 as described in Table 2-2 below.
Element
Description
Reset button
The button has three different functions:
•

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.
•
