Installing the IpChannel Bank 30
SmartNode 4900 User Manual 3 • Hardware installation
3. Select and attach the appropriate twisted-pair from each FXS device on punch-down blocks for connection
to the chosen port on the IpChannel Bank.
Connecting the Ethernet ports
The IpChannel Bank has dual 10/100 Ethernet interfaces. One is for the WAN connection. The other is for
connecting to your Ethernet LAN. The Ethernet ports will auto-sense the correct speed of the local LAN and
automatically negotiate to half- or full-duplex operation. This section describes connecting the IpChannel
Bank to the Ethernet LAN via an Ethernet hub or switch.
Connecting the 10/100Base-T Ethernet ports to an Ethernet switch or hub. The 10/100Base-T Ethernet
port is designed to connect to an Ethernet switch or hub with a straight-through or cross-over Ethernet cable.
The Ethernet RJ-45 pin and signal definitions for the SN4900 or for a NIC card in a workstation/PC are
shown in
figure 7 . Connect a CAT-5 cable (one wired as shown in figure 8 or figure 9 ) between the SN4900
and the hub/switch.
