Combination Ports and Failover

Summit family switches provide two or four uplink ports implemented as combination ports that pair a
copper port using RJ-45 connectors with an optical port using LC connectors. The copper port operates
as an autonegotiating 10/100/1000BASE-T port. The optical port allows Gigabit Ethernet uplink
connections through Extreme Networks small form factor pluggable (SFP) interface modules. See the
individual switch descriptions for the port numbers of the combination ports on each switch model.
Summit family switches support an automatic failover from an active fiber port to a copper backup or
from an active copper port to a fiber port. If one of the uplink connections fails, the Summit uplink
connection automatically fails over to the second connection. To set up a redundant link on one of the
combination ports, connect the active 1000BASE-T and fiber links to both the RJ-45 and SFP interfaces of
that port.
Gigabit Ethernet uplink redundancy on the Summit family switches follows these rules:
With both the SFP and 1000BASE-T interfaces connected on a combination port, only one interface
●
can be activated. The other is inactive.
If only one interface is connected, the switch activates the connected interface.
