Connectivity Rules

When adding hubs (repeaters) to your network, please follow the
connectivity rules listed below for these products. However, note that
because switches break up the path for connected devices into separate
collision domains, you should not include the switch or connected cabling
in your calculations for cascade length involving other devices.
