Connecting the Ethernet port
The IpChannel Bank has one 10/100 Ethernet interface for the WAN connection. The Ethernet port will
auto-sense the correct speed of the network 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 SN4300 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 SN4300 and the hub/switch.
