Port Connections
The Summit 300-24 switch uses a combination of 10BASE-T/100BASE-TX ports using RJ-45 connectors
and Small Form Factor Pluggable (SFP) Gigabit Interface Connectors (GBICs), also known as
mini-GBICs.
Ports 1 through 24 are 10/100BASE-T ports with RJ-45 connectors.
Ports 25 and 26 are Gigabit Ethernet ports that have redundant PHY interfaces for uplink redundancy.
The dual-media support consists of one mini-GBIC and one 1000BASE-T connection for each port. Only
one media type (fiber or copper) can be active at the same time.
The switch determines whether the port is the primary or redundant port based upon the order in
which the cables are inserted into the switch. When the switch senses that cables are in both the fiber
and corresponding copper port, the switch enables the uplink redundancy feature. For further
information, see "Summit 300 Automatic Failover" on page 74.
Ports 25 and 26 can be used as the interconnect ports in a Summit switch stacked configuration. For
more information about configuring and operating a Summit switch stack, see the ExtremeWare User
Guide.
Full-Duplex. The Summit 300-24 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 300-24 switch autonegotiate for half- or full-duplex
operation.

Indicates
Link is present; port is enabled.
Link is present, port is enabled, and there is activity on the port.
Link is not present, port is disabled, or non-supported GBIC is
installed on the port. The RJ-45 port is being used for the uplink.
Indicates
When several Summit "e" series switches are interconnected
(stacked), each switch is assigned a unique stacking ID number
that is visible in the unit stacking ID number LED. The switch
acting as the stack master is usually assigned the number 1.
However, if there is a saved configuration or if you prefer to
assign a different stacking ID to the stack master, the stack
master can have an ID other than 1.
