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, 1
meter 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
external redundant power supply (RPS). 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.

Connectivity

The switch connects to Ethernet networks or workstations via the fixed front panel RJ45
connectors and four uplink ports that support optional Mini‐GBICs.
At the time of this printing, the six Mini‐GBICs that are available from Enterasys are
described in Table
standard.
