Installing the IpChannel Bank 31SmartNode 4900 User Manual 3 • Hardware installationConnecting 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 BankRS-232 console port (figure 10) and an open serial port on your computer. If you need to assemble your owncable, refer to the pinout diagram in figure 10.Figure 10. DB-9-to-RJ-45 cable diagramConnecting the serial portSerial devices (V.35 or X.21) are connected to the SmartNode’s serial ports (see table 8) via a cable terminatedat the SmartNode 4900. The V.35 connector is a DB-25 female and the X.21 uses a DB-15 female. The syncserial ports are configured as DTE.Table 8.
