Connectivity
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 the 1000BASE‐T compliant fixed‐front panel RJ45 connectors and also use two uplink ports that support optional 10‐Gigabit fiber‐optic XFP transceivers for high‐speed uplinks to your network backbone.
At the time of this printing, three versions of the XFP transceivers that are available from Enterasys are described in Table 1‐1 on page 1‐3. These XFPs meet or exceed the IEEE 802.3ae 10‐Gigabit standard. For fiber optic and operating range specifications, refer to “Supported XFP Transceiver Interface Options” on page A‐3.
