3Com 5124M-TPCL manual Before Configuring the Module, Enabling Ports, Enabling Port Redundancy

Before Configuring the Module

When you first install the 24-Port Module in a managed concentrator:

1.The network (channel) defaults to isolated mode and all ports are automatically disabled so unapproved stations cannot be added. Therefore, you must use management commands to:

–Enable ports you want to use

–Assign enabled ports to backplane networks

2.All other module settings retain DIP switch default values.

Enabling Ports

You can enable or disable each of the ports on the 24-Port Module. When a port is enabled, it can transmit to and receive data from the network (channel) that the module or connector (bank) is assigned to.

To enable a port, use the following network management command:

SET PORT {slot.port} MODE {enable}

{slot.all} {disable}

Enabling Port Redundancy

Network management lets you set redundancy between ports. When you set two ports redundant to each other, the secondary port takes over if the primary port fails.

To set redundancy between ports, use the following management command:

SET PORT {slot.port} MODE {redundant} {slot.port} {non-redundant}

Refer to Chapter 2 for an example of port redundancy.
