18 Summit 200 Series Switch Installation and User Guide
Summit 200 Series Switch Overview
NOTE
To support automatic failover between the fiber and copper ports, you must use an Extreme mini-GBIC
connector.
Full-Duplex
The Summit 200-24 switch provides full-duplex support for all ports. Full-duplex allows frames to be
transmitted and received simultaneously and, in effect, doubles the bandwidth available on a link. All
10/100 Mbps ports on the Summit 200-24 switch autonegotiate for half- or full-duplex operation.
