High-Speed Stack Connections

The switch has 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. There are two types of cables:
• C2CAB‐SHORT cables to connect two adjacent switches in the stack, and
• C2CAB‐LONG cable to connect from the top switch to the bottom switch in the stack.
This cable can also be used in place of the C2CAB‐SHORT cable to connect switches
that are too far apart due to the physical arrangement of the switches in the stack.

Redundant Power Supply Capability

The switch has redundant power supply 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

You can connect this switch to Gigabit Ethernet networks or workstations by way of
optional Mini‐GBICs installed in the 24 SFP port slots for 1000BASE‐SX/‐EX/‐ELX
fiber‐optic connections and 1000BASE‐T copper connections.
At the time of this printing, the Mini‐GBICs supported and available from Enterasys are
described in Table
standard.
