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.

Redundant Power Supply Capability

The switch has power supply redundancy capability when connected to an optional SecureStack PoE‐compliant external redundant power supply (C2RPS‐POE). If the internal power supply fails, the RPS assumes the entire load of the switch without interrupting network traffic. The internal power supply and RPS each have their own AC power connection, which enables the connection of each power supply to a different AC power circuit for additional AC power source redundancy.
