High-Speed Stack Connections
The switches have rear‐panel connectors for high‐speed connections in a stack configuration. The high‐speed stacking cables used for the connections are optional items and must be ordered separately. Stacking cables are available in three lengths: 1 foot,
1meter, and 5 meters. See “Connecting High‐Speed Stacking Cables” on page 3‐11 for details on these cables.
