Repeater rules
The 100BASE-T standard defines two types of repeaters — Class I and Class II. The Express Stackable Hub is a Class I repeater. Class I repeaters (sometimes called translational repeaters) limit the number of repeaters in a physical domain to one.
However, the one-repeater maximum for Class I repeaters does not limit the port density of 100BASE-T networks when stackable hubs are used. Express Stackable Hubs can be stacked to form a single, multi-port repeater where each repeater stack can be managed like a single repeater unit.
Class I repeaters cannot be daisy-chained (connected to one another using UTP cabling).
