Collision domain assignments
All hubs running at the same speed in the stack belong to the same collision domain. In the example below, all devices (PCs, print servers, and so on) connected to hubs 1 and 2 share 100 Mbps of bandwidth. All devices connected to hubs 3 and 4 share 10 Mbps of bandwidth.

The entire hub is called the chassis.
The two collision domains don’t pass traffic to each other without optional bridging equipment (see the Intel Express 10/100 Stackable Hub User Guide that came with the hub for more information on bridging options).
MIB identification
If you use a MIB browser, you can configure or view statistics for the hub at three levels – by hub (chassis), module, or port. The MIB file locations are listed on page 51.

The group of base ports on the hubs are called modules. The expansion slots are also modules.
