How Stacks Work
Stackable hubs communicate with one another through proprietary
interconnection cables. The cables used in Cabletron Systems’ stackable hub
solution are called HubSTACK Interconnect Cables. In Ethernet stackable
environments, these cables are short, multistrand cables with special, D-shaped
connectors that attach to ports on the backs of the stackable hubs, as shown in
Figure 3-3. In Token Ring stackable solutions, the interconnect cables are short
twisted pair segments that connect each stackable unit directly to the base unit.
Figure 3-3. HubSTACK Interconnect Cables
The HubSTACK cables handle the communications between stackable devices,
including network traffic and management communications. The use of these
custom, short cables allows the stack to act as a single repeater or concentrator. In
essence, the cables and connectors used to chain the stackable hubs together
mimic the operation of the backplane of a modular hub.
