Equivalent Distances For 24-Port 10Base-T Module - IBM Nways 8260 Manual

When designing Ethernet segments consisting of the 8260 Ethernet 24-Port
10Base-T Module, you must use the following Equivalent Distances for this
module:
100
8260 Multiprotocol Intelligent Switching Hub
types of modules. For example, you can set a 10Base-T port on an 8260
Ethernet 24-Port 10Base-T Module to be a redundant port for 1 10Base-FB on
the 8260 Ethernet 10-Port 10Base-FB Module.
Auto-polarity detection
You can enable/disable auto-polarity detection for each port on the module.
When enabled, this feature will automatically detect if you have erroneously
reversed polarity of the cable during its assembly and will resolve the
problem by reversing the polarity.
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.
