Whether the combination of the devices are hub-to-switch, switch-to-switch, or hub-to-hub, the same rule applies!
In most cases there is one port which can be switched from "uplink" to "normal," so you can still use that port no matter what your needs are.
To help clear any doubts, here are some simple diagrams which indicate clearly what type of cable is used between different configurations:
UE= Uplink Exists --X--= crossover cable -----= Normal straight through cable Scenario 1: No Uplink available on either device Hub----X----Switch Hub-----X-----Hub Switch----X----Switch Scenario 2: Uplink available on one device only Hub(UE)--------Switch Hub(UE)--------Hub Switch(UE)-----Switch
Note: In the case both device have an uplink port, only one is used.
If you require more information on how hubs and switches connect and work, you can simply visit the following url: www.Firewall.cx and browse through the Networking/Connectivity section.
