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 10 Gbps, with combination
copper/fiber uplink ports. PoE connections and options for adding 10-Gbps or 100 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
make provision for redundant power supplies. Most models have connections for optional external
redundant power supplies; the Summit X480 series and X650 series switches provide two bays for
pluggable power supplies.
Most Summit models are available in versions that are compliant with the Trade Agreements Act (TAA);
these versions are identified by a -TAA suffix on the model number. Functionally, the TAA-compliant
models are completely equivalent to the matching versions that are not TAA-compliant. In all feature
descriptions, references to a specific Summit switch model also apply to the equivalent TAA-compliant
model.
Tab le 3 and Ta bl e 4 on page 14 and Ta bl e 5 on page 15 list the Summit switch series and summarize the
features available in each series.

Model numbers for the Summit switches are in the following format:
<Series>-<number of front-panel I/O ports><port type><power supply type>
● The number of ports can be 24 or 48.
● The port type can be t (copper), p (copper providing Power of Ethernet), or x (fiber).
● The power supply type can be AC (no designation) or DC.
For example, the Summit X350-24t switch is in the X350 series, provides 24 copper I/O ports, and has
an AC power supply. The Summit X450a-24xDC switch is in the X450a series, provides 24 fiber I/O
ports, and has a DC power supply.

Combination Ports and Failover
Summit family switches provide two, four, or twelve 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 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
16
Summit Family Switches Hardware Installation Guide
Page 17
connection automatically fails over to the second connection. To set up a redundant link on a
combination port, 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.
● 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 X250e-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:
● Summit X150-24t Switch
● Summit X150-24t-TAA Switch
● Summit X150-24p Switch
● Summit X150-24p-TAA Switch
● Summit X150-48t Switch
● Summit X150-48t-TAA Switch

Summit X250e-48p Power Supplies
The Summit X250e-48p switch is powered by both an internal power supply and an optional external
redundant power supply system.
Internal Power Supply
The internal Summit X250e-48p internal power supply can provide 370 W of PoE power, as follows:
● In a 24-port configuration, it provides 15.4 W to each port
● In a 48-port configuration or any combination of ports where total PoE power does not exceed 370
watts, it provides 7.7 W to each port.
If the total system demands exceed this power limit, you can specify one of the following:
● Port priorities to identify which ports should be ranked higher when allocating power
● Port disconnect precedence to specify the method of shutting off ports when not enough PoE power
is available
NOTE
For a detailed discussion of these concepts, see the Power over Ethernet section in the ExtremeXOS Concepts
Guide.
External Power Supplies
The EPS-600LS External Power Module provides optional redundant power for the Summit X250e-48p
switch. Through the redundant power input connector on the rear panel, the switch can be powered by
one, two, or three external power modules installed in the EPS-C External Power Supply Chassis.
The PoE capability of the Summit X250e-48p varies depending on the number of external power
modules in use. Tab le 8 summarizes the PoE power behavior for the Summit X250e-48p switch based on
the number of power supply modules in use.

Summit X350 Series Switches
The Summit X350 series switches provide 24 or 48 Ethernet ports that deliver high-density fast Ethernet
connectivity using fixed 10/100/1000BASE-T ports. Each Summit X350 series switch has four
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. 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 has an option slot to accommodate one of the following Summit option
cards:
■ Summit XGM2-2xf option card, which allows you to add one or two 10-gigabit XFP modules
■ Summit XGM2-2xn option card, which allows you to add one or two 10-gigabit XFP modules
■ Summit XGM2-2bt option card, which allows you to add one or two fixed 10GBASE-T ports
■ Summit XGM2-2sf option card, which allows you to add one or two 10-gigabit SFP+ modules
For option card installation instructions, see
Chapter 7, “Summit Option Cards.”
Power connectors on the rear panel of the switch include an AC power input socket and a redundant
power connector. The internal AC 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-500 external power supply. When a compatible external power supply is used with
the Summit X350 series switch, the internal and external power supplies are fully fault tolerant and
load-sharing. If one power supply fails, the other power supply provides sufficient power to operate the
switch.
The Summit X350 series switches include the following switches:
● Summit X350-24t Switch
● Summit X350-24t-TAA Switch
● Summit X350-48t Switch

different series are available both with and without PoE and in AC or DC power versions.
Each Summit X450, X450a, or X450e series switch has four combination ports that provide 10/100/1000
BASE-T or SFP connectivity for 4 Gbps of copper or fiber connectivity. A serial console port on the front
panel allows you to connect a terminal and perform local management. An Ethernet management port
on the back panel can be used to connect the system to a parallel management network for
administration. Alternatively, you can use an Ethernet cable to connect the Ethernet management port
directly to a laptop to view and locally manage the switch configurations.
The rear panel of the switch has an option slot to accommodate one of the following Summit option
cards:
● Summit XGM-2xn option card, which allows you to add one or two 10-gigabit XENPAK modules
● Summit XGM2-2xn option card, which allows you to add one or two 10-gigabit XENPAK modules
● Summit XGM2-2xf option card, which allows you to add one or two 10-gigabit XFP modules
Option card compatibility depends on the specific switch series. See the individual switch
descriptions for the option card supported on each switch. For option card installation instructions,
see
Chapter 7, “Summit Option Cards.”
Two high-speed stacking ports allow you to combine multiple units into a single SummitStack
management entity. Power connectors include an AC or DC power input socket and a redundant power
connector. (See specific switch descriptions for more information about the power options.) The switch
automatically adjusts to the supply voltage. The redundant power connector allows you to connect the
switch to the an external power supply. When a compatible external power supply is used with the
Summit X450, X450a, or X450e series switch, the internal and external power supplies are fully fault
tolerant. For most switches, if one power supply fails, the other power supply will provide sufficient
power to operate the switch. For information about power supply redundancy with the Summit
X450a-48p switch, see “Summit X450e-48p Power Supplies” on page 57.

Summit X450e-48p Power Supplies
The Summit X450e-48p switch is powered by both an internal power supply and an optional external
redundant power supply system.
Internal Power Supply. The internal Summit X450e-48p power supply can provide 370 W of PoE power,
as follows:
● In a 24 port configuration, it provides 15.4 W to each port.
● In 48-port configuration or any combination of ports where total PoE power does not exceed 370
watts, it provides 7.7 W to each port.
If the total system demands exceed this power limit, you can specify:
● Port priorities to identify which ports should be ranked higher when allocating power.
● Port disconnect precedence to specify the method of shutting off ports when not enough PoE power
is available.
NOTE
For a detailed discussion of these concepts, see the Power over Ethernet section in the ExtremeXOS Concepts
Guide.
External Power Supplies. The Summit X450e-48p switch can be powered by one, two, or three external
power modules through the redundant power input connector on the rear of the switch.
The EPS-C (External Power Supply Chassis) is shipped with the redundant power supply cable that
connects to the redundant input connector on the rear of the switch. The EPS-C chassis can hold from
one to three 600-Watt EPS-600LS (external power module) units.
The PoE capability of the Summit X450e-48p switch varies depending on the number of external power
modules in use. Tab le 1 1 summarizes the PoE power behavior for the Summit X450e-48p switch based
on the number of power supply modules in use.

Summit X480 Series Switches
The Summit X480 series switches are 24-port or 48-port switches that provide Ethernet connectivity
using fixed 10/100/1000BASE-T RJ-45 ports, installable SFP optical modules, or installable XFP
optical modules.
The Summit X480 series switches include the following base models:
● Summit X480-24x switch (see page 61)
● Summit X480-48x switch (see page 62)
● Summit X480-48t switch (see page 63)
A serial console port on the front panel of the Summit X480 series switch allows you to connect a
terminal and perform local management. 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 configuration.
The Ethernet management port supports 10/100/1000 Mbps speeds.
The rear panel of the switch provides a slot for an installed option card called a versatile interface
module or VIM. The types of VIM available for the Summit X480 series switches are:
● VIM2-SummitStack versatile interface module (see page 64)
Provides two 20-Gbps stacking ports
● VIM2-10G4X versatile interface module (see page 64)
Provides four 10-Gbps XFP ports
● VIM2-SummitStack128 versatile interface module (see page 65)
Provides two 64-Gbps stacking ports
NOTE
The Summit X480 switches are only compatible with VIM2 modules. Other VIM types that may appear to be
mechanically compatible with the Summit X480 switches will not function if they are installed in these switches.
Cooling is provided by a replaceable fan module. Two power supply bays accommodate either AC or

● Summit X250e-24tDC switch
● Summit X250e-24xDC switch
● Summit X250e-48tDC switch
● Summit X450a-24tDC switch
● Summit X450a-24xDC switch
● Summit X450a-48tDC switch
When this power supply is used one of the listed Summit switches, 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 EPS-T2 is a rack-mountable chassis or tray that holds one or two EPS-150DC power supplies. Each
EPS-150DC provides one-to-one redundancy to an attached Extreme switch. You must install the EPS150DC power supply in the EPS-T2 tray.

EPS-600LS External Power Module
The EPS-600LS External Power Module (Model 10913) is a 600-watt redundant power supply unit that
can be used with the following Extreme Networks switches:
● Summit X450e-48p switch
● Summit X250e-48p switch
NOTE
An AC power input cord is not provided with the EPS-600LS power module. You can order an appropriate cord from
Extreme Networks or from your local supplier. The power cord must meet the requirements listed in “Selecting
Power Supply Cords” on page 218.
Each EPS-C chassis is shipped with a special redundant power supply cord for connection to the Summit switch.
Make sure that the EPS-C chassis is installed in the equipment rack before installing an EPS-600LS power module.
PoE Redundant Power Configurations
You install one, two, or three EPS-600LS power modules in the EPS-C chassis (Model 10912) to build an
external redundant power system for the Summit switch. A redundant power cable shipped with the
EPS-C chassis provides the connection between the external power system and the redundant power
input connector on the back of the switch.
The PoE capability of the Summit X450e-48p or X250e-48p varies depending on the number of external
power modules in use. Ta bl e 1 7 summarizes the PoE power behavior for the Summit X450e-48p or
X250e-48p switch based on the number of power modules in use.

Single 600-LS Module Configuration: Redundant PoE Power
A single EPS-600LS power module provides redundant PoE power capability with the same 370-watt
capacity as the internal power supply. The internal Summit X450e-48p or X250e-48p power supply is
capable of 370 W of PoE power: 15.4 W supplied to each port for a 24-port configuration and 7.7 W
supplied to each port for a 48-port configuration.
● If the internal power supply fails, the external power module will provide power to PoE devices at
the same power levels as the internal power supply without any power interruptions.
● If the EPS-600LS power module fails or is removed, the internal power supply continues to provide
PoE power without any power interruptions.
Summit Family Switches Hardware Installation Guide

Page 78
Summit Power Supplies
Dual 600-LS Module Configuration: Full Power
Two EPS-600LS power modules provide full power at 740 W, which allows 15.4 W of PoE power to all
48 ports. In this full-power configuration, the internal power supply is disabled, and therefore
redundant power is not available.
Triple 600-LS Module Configuration: Full Redundant Power
Three EPS-600LS power modules provide the full 740 W of power for 15.4 W of PoE power to all 48
ports. In addition, this configuration provides 2:1 redundancy. Should one of the EPS-600LS power
modules fail, the third power module continues to provide uninterrupted full PoE power. The internal
power supply is disabled in this configuration.
Internal-to-External PSU Transfer
This section describes the conditions that would cause the Summit X450e-48p or X250e-48p switch to
draw power from the external power unit.
Internal PSU Failure with Single EPS-600LS Module. When an EPS-C with a single EPS-600LS is connected
to the Summit X450e-48p or X250e-48p switch and the internal PSU fails, power is drawn from the EPS600LS without power interruption to the PoE connected devices.
Two or Three EPS-600LS Modules. When the Summit X450e-48p or X250e-48p switch detects that an EPSC is connected and providing stable power from two or three EPS-600LS power modules, the PoE
power budget is automatically recalculated to enable 740 W of PoE power. The internal PSU is disabled
to prevent damage from excessive current demands beyond the internal PSU's capabilities.
External-to-Internal PSU Transfer
This section describes the conditions where power from an external power module either fails or is
disconnected.
Active Internal PSU with Single 600-LS Module Failure. When an EPS-C configured with a single EPS600LS module is connected to the Summit X450e-48p or X250e-48p switch and the EPS-600LS fails or is
disconnected, power is drawn from the internal PSU without power interruption to the PoE connected
devices.
Inactive Internal PSU with a Dual EPS-600LS Configuration and Module Failure. This section describes the
PoE behavior when an EPS-C chassis configured with two EPS-600LS modules is connected to the
Summit X450e-48p or X250e-48p switch and one or both EPS-600LS modules fail or are disconnected.
It is possible for one external power module to fail while the second power module continues to
function. If one EPS-600LS fails, the PoE power budget is automatically reduced to 370 W for the
Summit X450e-48p or X250e-48p switch. PoE port power management occurs as described in the Power
over Ethernet section of the ExtremeXOS Concepts Guide. With only a single operating power module,
the remaining EPS-600LS behaves as a redundant power module. The internal PSU is returned to an
active state to provide redundant capability.
78
If both external power modules fail or are disconnected, PoE power is interrupted while transferring
PoE power back to the internal PSU. The internal PSU is then limited to 370 W of PoE power. The PoE
power budget is automatically adjusted accordingly. Power management will occur as described in the
Power over Ethernet section of the ExtremeXOS Concepts Guide.
Summit Family Switches Hardware Installation Guide
Page 79
Disconnecting the EPS-C/EPS-600LS. To manually disconnect an EPS-C or to remove the EPS-600LS
modules, the recommended practice is to disconnect the EPS-600LS modules one at a time, pausing two
seconds between each EPS-600LS disconnect. This enables a graceful power transition from the external
PSUs to the internal PSU.
Example: Two active EPS-600LS modules in an EPS-C
a Unplug one EPS-600LS unit from its power source.
PoE power is automatically reduced to 370 watts and the internal PSU is enabled providing
redundant 370 watt PoE power.
b Wait at least two seconds before disconnecting the remaining EPS-600LS unit.
c Unplug the second EPS-600LS unit from its power source.
The internal PSU is already enabled and provides uninterrupted 370 watts of PoE power.
NOTE
After an EPS-600LS unit is disconnected from its power source, it may be removed from the EPS-C. See
“Removing an EPS-600LS Power Module” on page 193 for complete disconnect and removal details.
d Disconnect the EPS-C from the switch.
Summit X480 Power Supplies
The Summit X480 series switches can be powered by either of the following power supplies:
● Summit X480 AC power supply (Model 10917)
● Summit X480 DC power supply (Model 10918)
Either power supply provides 450 W of power to the switch.
The Summit X480 series switches accommodate one or two Summit X480 PSUs. In a redundant power
configuration, both power supplies are fully fault-tolerant and load-sharing. You can remove one power
supply without interrupting switch operation.
An AC power input cord is not provided with the Summit X480 AC power supply. You can order an
appropriate cord from Extreme Networks or from your local supplier. The power cord must meet the

This chapter includes the following sections:
● Planning Your Site on page 83
● Meeting Site Requirements on page 84
● Evaluating and Meeting Cable Requirements on page 88
● Meeting Power Requirements on page 93
● Applicable Industry Standards on page 95
By carefully planning your site, you can maximize the performance of your existing network and ensure
that it is ready to migrate to future networking technologies.
The information in this chapter is intended for the system administrator, network equipment technician,
network manager, or facilities manager responsible for installing and managing the network hardware.
The chapter assumes a working knowledge of local area network (LAN) operations, and a familiarity
with communications protocols that are used on interconnected LANs.
Installation, maintenance, and removal of a switch, chassis, or its components must be done by qualified
service personnel only. Qualified service personnel have had appropriate technical training and
experience that is necessary to be aware of the hazards to which they are exposed when performing a
task and of measures to minimize the danger to themselves or other people.
NOTE
Before installing or removing any components of the system, or before carrying out any maintenance procedures,
read the safety information in Appendix A of this guide.
Planning Your Site
To install your equipment successfully, you should plan your site carefully. The site planning process
has three major parts:
● Meeting site requirements
The physical installation site must meet the following requirements for a safe and successful
installation:
■ Building and electrical code requirements
■ Environmental, safety, and thermal requirements for the equipment you plan to install
■ Equipment rack requirements
● Evaluating and meeting cable requirements
After examining your physical site and verifying that all environment requirements are met, evaluate
and compare your existing cable plant with the requirements of the Extreme Networks equipment to
determine if you need to install new cables.

Site Preparation
● Meeting power requirements
To run your equipment safely, you must meet the specific power requirements for each switch and
external power supply unit installed in the system. For power specifications of the switches, see the
specific switch listings in Appendix B, “Technical Specifications.” For power specifications of the
external power supplies, see “Summit External Power Supplies” on page 261.
Meeting Site Requirements
This section requirements to consider when preparing your installation site, including:
● Operating Environment Requirements
● Rack Specifications and Recommendations
Operating Environment Requirements
Verify that your site meets all environmental and safety requirements.
Virtually all areas of the United States are regulated by building codes and standards. During the early
planning stages of installing or modifying your LAN, it is important that you develop a thorough
understanding of the regulations that pertain to your location and industry.
Building and Electrical Codes
Building and electrical codes vary depending on your location. Comply with all code specifications
when planning your site and installing cable. This section lists resources for obtaining additional
information.
Information about major building codes is located at the following websites:
● International Code Council (ICC); 5203 Leesburg Pike; Falls Church, Virginia 22041 USA.

Wiring Closet Considerations
Be aware of the following recommendations for your wiring closet:
● Be sure that your system is easily accessible for installation and service. See “Rack Specifications and
Recommendations” on page 86 for information.
● Use appropriate AC or DC power, power distribution, and grounding for your specific installation.
● Use a vinyl floor covering in your wiring closet. (Concrete floors accumulate dust, and carpets can
cause static electricity.)
● Prevent unauthorized access to wiring closets by providing door locks. Install the equipment in a
secured, enclosed, and restricted access location, ensuring that only qualified service personnel have
access to the equipment.
● Provide adequate overhead lighting for easy maintenance.
● Be sure that each wiring closet has a suitable ground. All equipment racks and equipment installed
in the closet should be grounded.
● Be sure that all system environmental requirements are met, such as ambient temperature and
humidity.
NOTE
Extreme Networks recommends that you consult an electrical contractor for commercial building and wiring
specifications.
Temperature
Extreme Networks equipment generates a significant amount of heat. It is essential that you provide a
temperature-controlled environment for both performance and safety.
Install the equipment only in a temperature- and humidity-controlled indoor area that is free of airborne
materials that can conduct electricity. Too much humidity can cause a fire. Too little humidity can
produce electrical shock and fire.
Follow these general thermal recommendations for your wiring closet:
● Be sure that the ventilation in the wiring closet is adequate to maintain a temperature below 104° F
(40° C).
● Install a reliable air conditioning and ventilation system.
● Keep the ventilation in the wiring closet running during non-business hours; otherwise, the
equipment can overheat.
● Maintain an ambient operating temperature of 32° to 104° F (0° to 40° C).
● Maintain a storage temperature of -40° to 158° F (-40° to 70° C).
Summit Family Switches Hardware Installation Guide
85
Page 86
Site Preparation
NOTE
As with all electrical equipment, Extreme Networks product lifetimes degrade with increased temperature. If
possible, temperatures should be kept at approximately 78° F (25° C) or lower.
Humidity
To maximize equipment life, keep operating humidity between 50% and 70% relative humidity (noncondensing) during typical operation. The equipment can operate between 10% and 95% relative
humidity (non-condensing) for short intervals.
Spacing Requirements and Airflow
Be sure that cables and other equipment do not block the air intake or outflow on an Extreme Networks
Summit family switch. It is best to have at least 3 inches (8 cm) of clear space in front of the air intake
and outflow vents on the sides of the switch; airflow moves from side to side. For proper airflow
through a Summit family switch, leave clear space on the left and right sides of the switch.
Depending on other conditions in the equipment room, it may be possible to install the switches closer
to each other; consult your Extreme Networks Customer Support representative for guidance.
Electrostatic Discharge
Your system must be protected from static electricity or electrostatic discharge (ESD). Take the following
measures to ensure optimum system performance:
● Remove materials that can cause electrostatic generation (such as synthetic resins) from the wiring
closet. Check the appropriateness of floor mats and flooring.
● Connect metal chassis, conduit, and other metals to ground using dedicated grounding lines.
● Use electrostatically safe equipment. If you are working with pluggable interface modules, wear an
ESD-preventive wrist strap and connect the metal end to a grounded equipment rack or other source
of ground.
Rack Specifications and Recommendations
Racks should conform to conventional standards. In the United States, use EIA Standard RS-310C:
Racks, Panels, and Associated Equipment. In countries other than the United States, use IEC Standard
297. In addition, verify that your rack meets the basic mechanical, space, and earthquake requirements
that are described in this section.
86
Summit Family Switches Hardware Installation Guide
Page 87
Mechanical Recommendations for the Rack
Use equipment racks that meet the following mechanical recommendations:
● Use an open style, 19-inch rack to facilitate easy maintenance and to provide proper ventilation.
● Use a rack made of steel or aluminum.
● The rack should use the universal mounting rail hole pattern that is identified in IEC Standard 297.
● The rack should have designated earth grounding connections (typically on the base).
● The rack must meet earthquake safety requirements equal to that of the installed chassis.
● The mounting holes should be flush with the rails to accommodate the chassis.
● The rack should support approximately 600 pounds (272 kilograms).
Protective Grounding for the Rack
Use a rack grounding kit and a ground conductor that is carried back to earth or to another suitable
building ground.
At a minimum, follow these guidelines to ground equipment racks to the earth ground:
● CAD weld appropriate wire terminals to building I-beams or earth ground rods.
● For a Summit DC-powered switch, use a minimum 14 AWG stranded copper wire for grounding.
AC-powered Summit switches do not need separate chassis grounding.
● Position the earth ground as close to the equipment rack as possible to maintain the shortest wiring
distance possible.
● Use a ground impedance tester or micro-ohm meter to test the quality of earth ground connection at
the chassis. This will ensure good grounding between the chassis, rack, and earth ground.
NOTE
Because building codes vary worldwide, Extreme Networks strongly recommends that you consult an electrical
contractor to ensure proper equipment grounding for your specific installation.
Space Requirements for the Rack
Provide enough space in front of and behind the switch so that you can service it easily. Allow a
minimum of 48 inches (122 cm) in front of the rack and 30 inches (76 cm) behind the rack. When using a
relay (two-post) rack, provide a minimum of 24 inches (61 cm) of space behind the mounted equipment.
Extra room on each side is optional.
WARNING!
Extreme Networks switches do not have a switch for turning power to the unit on and off. For systems using an AC
power supply, power to the switch is disconnected by removing the wall plug from the electrical outlet.
For DC-powered Summit switches (X450a-24tDC, X450a-24xDC, and X450a-48tDC) and the EPS-150DC power
supply, turn off power to the chassis by de-energizing the circuit that feeds the power supply; this is usually
accomplished by turning off a circuit breaker. Disconnecting the DC wiring harness from the DC power source
requires the performance of a qualified, licensed electrician.

Site Preparation
Securing the Rack
The rack should be attached to the wiring closet floor with 3/8-inch (9.5 mm) lag screws or equivalent
hardware. The floor under the rack should be level within 3/16-inch (5 mm). Use a floor-leveling
cement compound if necessary or bolt the racks to the floor as shown in Figure 65.
Figure 65: Properly Secured Rack

Brace open equipment racks if the channel thickness is less than 1/4 inch (6.4 mm).
Evaluating and Meeting Cable Requirements
This section addresses requirements for the cable you should use when installing your network
equipment. It includes:
● Cabling Standards
● Cable Labeling and Record Keeping
● Installing Cable
● RJ-45 Connector Jackets
● Radio Frequency Interference
Cabling Standards
Extreme Networks recommends using the Building Industry Consulting Service International (BICSI)
Registered Communications Distribution Designer (RCDD), which is globally recognized as a standard
in site planning and cabling. For information, go to:
http://www.bicsi.org
88
Summit Family Switches Hardware Installation Guide
Page 89
Cable Labeling and Record Keeping
A reliable cable labeling system is essential when planning and installing a network. Maintaining
accurate records helps you to:
● Relocate devices easily.
● Make changes quickly.
● Isolate faults in the distribution system.
● Locate the opposite end of any cable.
● Know the types of network devices that your cabling infrastructure can support.
Follow these guidelines when setting up a cable labeling system suitable for your installation:
● Identify cables by securely attaching labels to all cable ends.
● Assign a unique block of sequential numbers to the group of cables that run between each pair of
wiring closets.
● Assign a unique identification number to each equipment rack.
● Identify all wiring closets by labeling the front panel of your Extreme Networks equipment and
other hardware.
● Keep accurate and current cable identification records.
● Post records near each equipment rack. Include the following cable drop information: the cable
source, destination, and jumper location.
Installing Cable
Consider the following recommendations when you connect cable to your network equipment:
● Examine cable for cuts, bends, and nicks.
● Support cable using a cable manager that is mounted above connectors to avoid unnecessary weight
on the cable bundles.
● Use cable managers to route cable bundles to the left and right of the network equipment to
maximize accessibility to the connectors.
● Provide enough slack, approximately 2 to 3 inches (5.08 to 7.62 cm), to provide proper strain relief as
shown in Figure 66.
● Bundle cable using hook-and-loop straps to avoid injuring cables.
● If you build your own cable, be sure that connectors are properly crimped.
● When installing a patch panel using twisted pair wiring, untwist no more than 1 inch (2.54 cm) of
the cable to avoid radio frequency (RF) interference.
● Discharge the RJ-45 Ethernet cable before plugging it into a port on the switch.
CAUTION
Unshielded twisted pair (UTP) cable can build up ESD charges when being pulled into a new installation. Before
connecting any category 5 UTP cable to the switch, discharge ESD from the cable by plugging the RJ-45
connector into a LAN static discharge device or use an equivalent method.

Site Preparation
● Use plenum-rated cable when it is necessary for safety and fire rating requirements. Consult your
local building codes to determine when it is appropriate to use plenum-rated cable, or refer to IEC
standard 850.
● Keep all ports and connectors free of dust.

Fiber Optic Cable
Fiber optic cable must be handled carefully during installation. Every cable has a minimum bend
radius, for example, and fibers will be damaged if the cables are bent too sharply. It is also important
not to stretch the cable during installation. We recommend that the bend radius for fiber optic cable
equal 2 inches (5.08 cm) minimum for each 90-degree turn as shown in Figure 67.
Summit Family Switches Hardware Installation Guide
Page 91
NOTE
Kinks and sharp bends can destroy or impair the cable’s ability to convey light pulses accurately from one end of the
cable to the other. Use care in dressing the optical fiber cables: provide satisfactory strain relief to support the cable
and maintain an adequate bend radius at all cable turns, particularly where the cable connects to the I/O module.

RJ-45 Connector Jackets
Use RJ-45 cable with connector jackets that are flush with the connector or that have connectors with a
no-snag feature.
Using cable with jackets that are wider than the connectors can cause:
● Connectors that are not properly aligned with the port.
● Crowded cable installation, which can cause connectors to pop out of the port.
Figure 68 shows examples of connector jacket types that are not recommended as well as those that are
recommended.

Radio Frequency Interference
If you use UTP cabling in an installation, take precautions to avoid RF interference. RF interference can
cause degradation of signal quality, and, in an Ethernet network environment, can cause excessive
collisions, loss of link status, or other physical layer problems that can lead to poor performance or loss
of communication.
To prevent RF interference, avoid the following situations:
● Attaching UTP cable to AC power cables
● Routing UTP cable near antennas, such as a ham radio antenna
● Routing UTP cable near equipment that could exhibit RF interference, such as ARC welding
equipment
● Routing UTP cable near electrical motors that contain coils
● Routing UTP cable near air conditioner units
● Routing UTP cable near electrical transformers
In areas or applications where these situations cannot be avoided, use fiber optic cabling or shielded
twisted pair cabling (STP).

Meeting Power Requirements
This section describes power requirements, including:
● PoE Devices
● Power Supply Requirements
● AC Power Cables
● Uninterruptible Power Supply Requirements
PoE Devices
When connecting power over Ethernet (PoE) devices to a PoE switch, all connections between the PoE
device and the switch must remain within the same building and use a low-voltage power distribution
system per IEEE 802.3af.
Power Supply Requirements
Follow these recommendations when you plan power supply connections for the Summit family
switches:
● Place the equipment in an area that accommodates the power consumption and component heat
dissipation specifications.
● Be sure that your power supply meets the site DC power or AC power requirements of the network
equipment.
● When you connect power to installed equipment, do not make this connection through an extension
cord or power strip.
● If your switch includes more than one power supply, connect each power supply to a different,
independent power source.
If a power source fails, it will affect only the switch power supply to which it is connected. If all
switch power supplies are connected to a single power source, the entire switch is vulnerable to a
power source failure.
● In regions that are susceptible to electrical storms, we recommend that you plug your system into a
surge suppressor.
For power specifications for the Summit family switches, see Appendix B, “Technical Specifications.”
AC Power Cables
AC power input cords are not provided with Summit switches and power supplies. You can purchase
AC power cords for use in the US and Canada from Extreme Networks or from your local supplier.
Power supply cords for use outside of the United States and Canada are typically provided separately
by third-party distribution centers. Make sure that the power cord you use is certified for the country of
end use and suitable for the device.
The power cord must meet the requirements listed in “Selecting Power Supply Cords” on page 218.

Uninterruptible Power Supply Requirements
An uninterruptible power supply (UPS) is a device that sits between a power supply (such as a wall
outlet) and a device (such as a switch) to prevent outages, sags, surges, and bad harmonics from
adversely affecting the performance of the device.
A UPS traditionally can perform the following functions:
● Absorb relatively small power surges.
● Smooth out noisy power sources.
● Continue to provide power to equipment during line sags.
● Provide power for a period of time after a blackout has occurred.
In addition, some UPS devices or UPS-plus-software combinations provide the following functions:
● Automatically shut down equipment during long power outages.
● Monitor and log power supply status.
● Display the voltage (current draw) of the equipment.
● Restart equipment after a long power outage.
● Display the voltage currently on the line.
● Provide alarms on certain error conditions.
● Provide short-circuit protection.
Selecting a UPS
To determine UPS requirements for your switch, answer these questions:
● What are the amperage requirements?
● What is the longest potential time period that the UPS would be required to supply backup power?
● Where will the UPS be installed?
● What is the maximum transition time that the installation will allow? (See “UPS Transition Time” on
page 95)
NOTE
Extreme Networks recommends that you use a UPS that provides online protection.
Calculating Volt-Amperage Requirements
To determine the size of UPS that you need:
1 Locate the voltage and amperage requirements for each piece of equipment. These numbers are
usually located on a sticker on the back or bottom of your equipment. Then multiply the numbers
together to get Volt-Amperes (VA):
VA = Volt s x A mpe re s
2 Add the VA from all the pieces of equipment together to find the total VA requirement.
To determine the minimum volt-amperage requirements for your UPS, Extreme Networks
recommends that you add 30% to the total.

UPS Transition Time
Transition time is the time that is necessary for the UPS to transfer from utility power to full-load
battery power. For Extreme Networks products, a transition time of less than 20 milliseconds is required
for optimum performance.
DC Power Requirements
This system should be installed in a DC-I battery return configuration.In a DC-I configuration, the
battery return conductor should be connected directly to the central office power return bus, and not to
the equipment frame or the grounding means of the equipment.

4 Building a SummitStack Configuration
This chapter provides information about how to build and connect a SummitStack configuration. If you
intend to use the SummitStack feature, read this chapter before installing the set of Summit family
switches that will be included in the SummitStack configuration.
For instructions to install Summit family switches in equipment racks, see Chapter 5.
The chapter includes the following topics:
● Stacking Summit Family Switches on page 97
● Placing Summit Family Switches for Stacked Operation on page 100
● Connecting the Switches to Form the Stack Ring on page 101
● Connecting Stacking Cables on page 108
● Connecting Console Ports for a Stack on page 118
● Management Port Cabling on page 118
● Stacking Port LEDs on page 118
Stacking Summit Family Switches
A stack consists of a group of up to eight Summit switches that are connected together using stacking
cables to form a connected ring, as shown in Figure 69. The stack can combine any Summit series
switches that include support for stacking, as long as you follow port compatibility and cabling
recommendations. See “Placing Summit Family Switches for Stacked Operation” on page 100 and
“Connecting the Switches to Form the Stack Ring” on page 101 for more information about combining
switches from different Summit series.

The stack operates as a single switch with a single IP address and a single point of authentication. One
switch, called the stack master, controls the stack. The master runs ExtremeXOS software and maintains

Building a SummitStack Configuration
all the software tables for all the switches in the stack. A stack of switches can have only one master
switch. All switches in the stack, including the master switch, are called nodes.
Slot Numbers
A stack can be thought of as a virtual chassis. Each node operates as if it were occupying a slot in a
chassis and is controlled by the master. The high-speed stacking links function like the backplane links
of a chassis.
Each switch (or node) in the stack is assigned a “slot number” during the initial software configuration
of the stack. Starting at the switch with the console connection, numbers are assigned in numerical
order following the physical path of the connected stacking cables. For example, if you follow the
cabling recommendations presented in “Connecting the Switches to Form the Stack Ring” on page 101
and configure a vertical stack from the console on the switch at the top of the physical stack, the
switches Figure 71 will be assigned numbers 1 through 8 from the top down.
Each Summit switch has a seven-segment LED on its front panel, called the stack number indicator.
When a stack is operating, the indicator displays the slot number for the switch. This LED does not
light on switches that are not operating in stacking mode. A quick way to verify that the cable
connections match the software configuration is to check the stack number indicator on each switch. If
the slot numbers do not line up in the order you arranged the switches, this may indicate that the
stacking cable setup differs from what you intended when you configured the software. In this case,
reconnect the cables in the correct order and perform the software configuration again.
About Redundancy
When your stack is operational, one switch is the primary (or master) switch that is responsible for
running network protocols and managing the stack. To provide recovery in case of a break in the stack
connections, you can configure redundancy by designating a backup switch to take over as master if the
master switch fails. When you perform the initial software configuration of the stack, the “easy setup”
configuration option automatically configures redundancy, with slot 1 as the master and slot 2 as the
backup. You can also configure additional switches as “master-capable” to become a stack master in
case the initial backup switch fails.
In a stack that combines Summit X480 series or X650 series switches with other Summit switch models,
a Summit X480 or X650 series switch might provide more memory and more features than other
Summit switch models in the stack. These differences can affect master node selection, backup node
selection, and failover operation. The master and backup roles should be assigned to switches from the
same series. For example, if the master node is a Summit X480 series switch, the backup node should
also be a Summit X480 switch. Similarly, if the master node is a Summit X650 series switch, the backup
node should also be a Summit X650 switch.
In a stack that combines Summit X480 series switches with Summit X650 series switches, Extreme
Networks recommends assigning the master/backup roles to two Summit X480 series switches.
In a stack with multiple master-capable switches, it is possible for more than one switch to try become
the stack master if the stack is physically severed. Such a dual-master condition would cause confusion
and loss of connectivity in your network. To resolve a dual-master condition, you must be able to log in
to each severed stack segment, either over the management network (using the Ethernet management
port on a switch in the segment) or through a direct console port connection to each switch in the
segment.

Stacking Cables
Depending on the switch model and the number and type of stacking ports the bidirectional stacking
link provides 40 Gbps, 256 Gbps, or 512 Gbps full duplex bandwidth. Stacking connections are made
using stacking cables that are specific to the type of stacking port. These cables are available from
Extreme Networks in lengths from 0.5 meter to 5 meters. Tab le 19 lists the cable types and compatible
Summit switches or modules.

Placing Summit Family Switches for Stacked Operation
This section summarizes the recommended best practices for installing Summit switches for a
SummitStack configuration. For detailed information about how to configure and manage the stack and
how a stack operates, refer to the ExtremeXOS Concepts Guide.
When you install switches for a SummitStack configuration, follow these recommendations:
● Use the shortest possible stacking cables to connect the switches in the stack; this reduces the
likelihood that the stacking cables might be accidentally damaged or disconnected. Stacking cables
are available in lengths from 0.3 meters to 5 meters (see Tab le 19 ).
● When possible, place all switches for the stack in the same rack or in adjacent racks; this facilitates
using shorter stacking cables.
● The stack master is the switch through which you will perform the initial stack configuration, using
the console port. For simplicity and ease of connecting the stacking cables, plan to designate the top
switch in a vertical physical stack as the stack master. If switches are installed in several adjacent
racks, place the stack master at one end of the row.
● Physically locate the intended master and backup nodes adjacent to each other, and connect these
switches directly to each other.
● For easier software configuration of the stack, connect the stacking cables in the order and
arrangement shown in the tables that accompany the examples.
● On the stack master switch, connect the Ethernet management port to your management network.
● To provide management access to the stack in case of a failure in the master switch, connect all
switches that will participate in redundancy to your management network using the Ethernet
management port on each switch.
● Because of the weight of the cable, Extreme Networks strongly recommends the use of cable
management hardware to support the cables and provide strain relief at the connectors when you
use the SummitStack 128G cable, SummitStack 64G cable, or SummitStack 128G/64G cable (see
“Connecting Stacking Cables” on page 108).
