3 • Hardware installation
Connecting a 10/100Base-T Ethernet port to an Ethernet-capable workstation. The 10/100Base-T Ether-
net ports can connect to a single Ethernet-capable workstation or PC by means of any Ethernet cable.
Connecting the EIA-561 RS-232 configuration port (DCE configured)
Install the supplied RJ-45-to-RJ-45 cable with the DB9-RJ45 adapter between the SN4900 IpChannel Bank
RS-232 console port (
figure 10
) and an open serial port on your computer. If you need to assemble your own
cable, refer to the pinout diagram in
figure 10
.
Figure 10. DB-9-to-RJ-45 cable diagram
Connecting the serial port
Serial devices (V.35 or X.21) are connected to the SmartNode’s serial ports (see
table 8
) via a cable terminated
at the SmartNode 4900. The V.35 connector is a DB-25 female and the X.21 uses a DB-15 female. The sync
serial ports are configured as DTE.
