This chapter describes the Summit family switches. The chapter includes the following sections:
●Overview of the Summit Switches on page 15
●Summit X150 Series Switches on page 17

Overview of the Summit Switches
The Summit family switches are compact enclosures 1.75 inches high (1 U). They provide 24 or 48
high-density copper or fiber optic ports operating at speeds up to 1 Gbps, with combination
copper/fiber uplink ports. PoE connections and options for adding 10-Gbps uplink connections are
available on some models. Many Summit switches include high-speed stacking interfaces that allow you
to connect up to eight Summit switches into a single SummitStack® management entity. Summit models
are available for AC or DC power connection; all Summit switches have connections for optional
external redundant power supplies.
Table 3 lists the Summit switch series and summarizes the features available in each series.

NOTE
See the ExtremeXOS 12.0 Concepts Guide and the ExtremeXOS 12.0 Command Reference Guide for feature-specific
information about the Summit switches and for information regarding switch configuration.
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.

Summit Family Switches Hardware Installation Guide 17
●The switch determines whether the port uses the fiber or copper connection based on the order in
which the connectors are inserted into the switch. When the switch senses that an SFP and a copper
connector are inserted, the switch enables the uplink redundancy feature. For example, if you first
connect copper ports 25 and 26 on a Summit XX250e-24t switch, and then insert SFPs into ports 25
and 26, the switch assigns the copper ports as active ports and the fiber ports as redundant ports.
Hardware determines when a link is lost and swaps the primary and redundant ports to maintain
stability. After a failover occurs, the switch keeps the current port assignment until another failure
occurs or a user changes the assignment using the CLI. For more information about configuring
automatic failover on combination ports, see the ExtremeXOS Concepts Guide.
Summit X150 Series Switches
The Summit X150 series switches provide 24 or 48 fixed 10/100BASE-T Ethernet ports that deliver
high-density copper connectivity for 2.4 Gbps or 4.8 Gbps. Models are available with PoE and without
PoE. Each Summit X150 series switch has two combination ports that provide 10/100/1000 BASE-T or
SFP connectivity for 2 Gbps of copper or fiber connectivity. A serial console port on the front panel
allows you to connect a terminal and perform local management. On the back of the switch, an Ethernet
management port can be used to connect the system to a parallel management network for
administration. Alternatively, you can use an Ethernet cable to connect this port directly to a laptop to
view and locally manage the switch configurations.
The rear panel of the switch provides an AC power input socket and a redundant power connector. The
internal power supply operates from 100 VAC to 240 VAC. The switch automatically adjusts to the
supply voltage. The redundant power connector allows you to connect the switch to the EPS-160 or
EPS-500 external power supply. When a compatible external power supply is used with the Summit
X150 series switch, the internal and external power supplies are fully fault tolerant and load-sharing.
If one power supply fails, the other power supply will provide sufficient power to operate the switch.
The Summit X150e series switches include the following switches:
