and Devices
The 10B2 connection and the Uplink port on the 3C1011C Call Processor
are two different connection points for a single port. They cannot be
used simultaneously.
If you use the Uplink connector, be sure to program the switch or router
on the other end for 10 MB operation.
You do not need to connect cards to each other within a chassis. They are
connected by the chassis backplane.
Do not connect telephone lines or 3Com telephones yet.
Establishing SuperStack 3 NBX LAN Connections
Connect the SuperStack 3 NBX Call Processor to your LAN using the
Ethernet 1 port. The Ethernet 2 port is a fail-over port that is active only if
the Ethernet 1 port experiences a link failure. This port can operate at 10
Mbps and 100 Mbps; it automatically senses the speed of your LAN.
Connect the NBX Gateway chassis to your LAN using one of these:
The 10 Mbps shared connector — Operates at 10 Mbps only
■
The upper 10/100 Mbps connector — Operates at either 10 Mbps or
■
100 Mbps and automatically senses the speed of your LAN
The lower 10/100 Mbps RJ45 connector — Operates at either
■
10 Mbps or 100 Mbps and automatically senses the speed of your
LAN
You do not need to connect cards to each other within an
NBX Gateway chassis. They are connected by the chassis backplane.
Do not connect telephone lines or 3Com telephones yet.
After you configure and test the NBX system, you are ready to connect
and configure cards into the chassis and attach optional devices such as
