Auto Polarity; Network Selection - 3Com CoreBuilder 5000 User Manual

Configuring the Module 3-15
The following output is an example of the SET PORT ALERT_FILTER
command issued for port 1 of a module in slot 1:
CB5000> set port 1.1 alert_filter disable [ENTER]
Port 01.01 Alert Filter set to DISABLE.
For more information on this command, refer to the Distributed
Management Module Commands Guide.

Auto Polarity

Auto Polarity enables the 24-Port module to automatically switch the
polarity of twisted-pair cabling. If, for instance, you erroneously reverse
the polarity of some twisted pair cabling while assembling it, Auto
Polarity enables you to automatically detect this problem and reverse
the polarity.
Use the following network management command to enable Auto
Polarity for a port:
SET PORT { slot.port } AUTO_POLARITY {enable}
{ slot. all} {disable}

Network Selection

The CoreBuilder 5000 Ethernet 24-Port Module provides port-level
configuration flexibility using the CoreBuilder 5000 hub's unique
architecture. You can assign ports collectively or individually, to any of
eight backplane networks (or isolated module segments). Refer to
Chapter 1 in the CoreBuilder 5000 Integrated System Hub Installation
and Operation Guide for a complete discussion of the CoreBuilder 5000
hub architecture.
The dip switch settings on the module refer to the backplane
connection as the "channel" selection (CH SEL). The channel setting
and the network setting are the same.
The dip switch settings on the 24-Port module let you assign all ports
(collectively) on the module to network 1 through 8 or to an isolated
segment. Network management, however, lets you assign one or more
ports to a network. If you have a CoreBuilder 5000 Ethernet Network
Monitor Card, network management also enables you to assign the
monitor card to a network.
