Support for port redundancy
You can set up redundancy between two links on the same module or two
different modules. Note that port redundancy is supported between different
types of modules. For example, you can set a 10Base-T port on an 8260
Ethernet 20-Port 10Base-T Module to be a redundant port for a port on an
8260 Ethernet 10-Port 10Base-FB Module.
Support for non-10Base-T compliant devices
This module allows you to disable link integrity which allows connection to
some equipment that does not conform to the 10Base-T standard.
When designing Ethernet segment consisting of the 20/40-port 10Base-T
modules, you must use the following
Equivalent Distances
for this module:
Figure 69 on page 108 shows the front view of the 20/40-port 10BASE-T modules.
As can be seen, these modules provide you with LED Indicators on the front
panel that allow you to monitor the status of the module and the individual ports.
