3Com 5124M-TPCL Switch User Manual


 
Introduction 1 - 3
Is designed with all ports internally crossed over, as required by the
10BASE-T standard. This enables you to connect the 24-Port Module
to a 10BASE-T transceiver without using an external crossover
adapter.
Bank Switching Capability
Bank switching is the assignment of a group of twelve consecutive ports to
a single network, or to an isolated network.
In an unmanaged concentrator you can use DIP switches to:
Assign all module ports to an Ethernet network or to an isolated
network
Assign port groups 1 through 12 or 13 through 24 to different
Ethernet or isolated networks
In a managed concentrator you can use network management commands
to assign the following port “groups” to any of three backplane networks,
or to either of two isolated networks:
Ports 1 through 12
Ports 13 through 24
All ports on the module
