Enterasys Networks C2H124-48P, C2G124-48P manual High-Speed Stacking Cable Connections

Connecting High-Speed Stacking Cables

Note: The high-speed stacking cables are optional items and must be ordered separately. There are two types of cables:

• C2CAB-SHORT cable to connect two adjacent switches in the stack.

•C2CAB-LONG cable to connect from the top switch to the bottom switch in the stack. You only need one C2CAB-LONG cable per stack.

•If the stack is in a configuration where the adjacent switches are two far apart for the short cables, the long cable can be used for the connections.

Figure 3‐7 shows an example of a four‐high stack connected in a ring topology. All STACK DOWN and STACK UP connectors used in the installation. The high‐speed stacking cable

(1)connections are from the STACK DOWN connector (2) of one switch to the STACK UP

(3)connector of the next switch up in the stack. A high‐speed stacking cable connection from the STACK DOWN (4) connector of the switch at the top of the stack to the STACK UP (5) connector at the bottom of the stack completes the ring connection. In a daisy chain topology, one cable is not used.
