equipment technician, or network manager responsible for installing and managing the network
hardware. It 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.
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.
To learn more about safety issues and to ensure safety compliance, see Appendix A.
Service to all equipment should be performed by trained and qualified service personnel only! Before installing or
removing any components of the system, or before carrying out any maintenance procedures, you must read the
safety information provided in Appendix A of this guide.
To install your equipment successfully, you should plan your site carefully. The site planning process
has three major parts:
● Meeting Site Requirements
● Evaluating and Meeting Cable Requirements
● Meeting Power Requirements
Meeting Site Requirements
Your 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
● Distribution rack requirements
Evaluating and Meeting Cable Requirements
After examining your physical site and ensuring 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 (or cabling).
Meeting Power Requirements
To run your equipment safely, you must meet the specific power requirements for each power supply
unit installed in the system.
Meeting Site Requirements
This section addresses the various requirements to consider when preparing your installation site,
including:
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. The following sections are provided as a resource to
obtain additional information.
Information on major building codes is located at the following websites:
● International Code Council (ICC); 5203 Leesburg Pike; Falls Church, Virginia 22041 USA.
http://www.iccsafe.org
http://www.sbcci.org
Five authorities on electrical codes are:
● National Electrical Code (NEC) Classification (USA only)—a recognized authority on safe electrical
wiring. Federal, state, and local governments use NEC standards to establish their own laws,
ordinances, and codes on wiring specifications. The NEC classification is published by the National
Fire Protection Association (NFPA). The address is NFPA; 1 Batterymarch Park; Quincy,
Massachusetts 02169 USA.
● Underwriters’ Laboratory (UL) (USA only)—an independent research and testing laboratory. UL
http://www.nfpa.org
evaluates the performance and capability of electrical wiring and equipment to determine whether
they meet certain safety standards when properly used. Acceptance is usually indicated by the
words “UL Approved” or “UL Listed.” The address is UL; 333 Pfingsten Road; Northbrook, Illinois
60062-2096 USA.
● National Electrical Manufacturing Association (NEMA) (USA only)—an organization of electrical
http://www.ul.com
product manufacturers. Members develop consensus standards for cables, wiring, and electrical
components. The address is NEMA; 1300 N. 17th Street; Rosslyn, Virginia 22209.
● Electronics Industries Alliance (EIA)—a trade association that develops technical standards,
http://www.nema.org
disseminates marketing data, and maintains contact with government agencies in matters relating to
the electronics industry. The address is EIA; 2500 Wilson Boulevard; Arlington, Virginia 22201 USA.
http://www.eia.org
● Federal Communications Commission (FCC)—a commission that regulates all interstate and foreign
electrical communication systems that originate in the United States according to the
Communications Act of 1934. The FCC regulates all U.S. telephone and cable systems. The address is
FCC; 445 12th Street S.W.; Washington, D.C. 20554 USA.
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 27 for information.
● Use appropriate AC 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 distribution 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.
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 ambient operating temperature: 32° to 104° F (0° to 40° C).
● Maintain storage temperature: -40° to 158° F (-40° to 70° C).
Like all electrical equipment, product lifetimes degrade with increased temperature. If possible, temperatures should
be kept at approximately 78° F (25° C) or lower.
Extreme Networks recommends placing no more than three chassis next to each other due to chassis-tochassis heating. The following are some general recommendations for installing your BlackDiamond
10808 switch, BlackDiamond 8800 series of switches, or your BlackDiamond 12804 switch:
● A minimum of one empty 19-inch rack between each set of three adjacent BlackDiamond switches.
or
● Place patch panels between each set of three adjacent BlackDiamond switches. A patch panel does
not require any power and does not generate any heat.
Up to five adjacent switches will continue to function without safety concerns. However, product lifetime may
degrade with continued exposure to high temperatures in close proximity and long term reliability may be
compromised.
Summit Family of Switches Spacing Requirements
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.
BlackDiamond Family Chassis Airflow Requirements
To ensure proper airflow through a BlackDiamond switch, refer to the following recommendations
when you are installing your switch:
● BlackDiamond 10808 switches require a minimum of 3 inches (8 cm) around both the front and rear
of the chassis from any cabinet wall or other obstruction for proper airflow.
● BlackDiamond 8800 and 12804 switches require a minimum of 1.5 inches (4 cm) around both the left
and right sides of the chassis from any cabinet wall or other obstruction for proper airflow.
● Air temperature measured approximately 1 inch (2.5 cm) from the fan inlet should be less than
104 °F (40 °C).
The airflow of the BlackDiamond 10808 switch, BlackDiamond 8800 series of switches, and
BlackDiamond 12804 switch moves through the power supplies and is independent of the airflow
through the modules as shown in Figure 1 and Figure 2.
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 and the ESD-preventive wrist strap that is provided with your
equipment. All switches come with ESD-preventive wrist strap connectors and an ESD-preventive
wrist strap as shown in Figure 3.
Figure 3: Using an ESD-preventive wrist strap
Humidity
Operating humidity should be kept between 50 to 70% relative humidity non-condensing during typical
operation and 10% to 95% relative humidity (non-condensing) for short intervals to maximize
equipment life.
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.
Use distribution 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.
● Install equipment into the lower half of the rack first to avoid making the rack top-heavy.
● 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.
All Extreme Networks switches are designed with mounting brackets that provide solid metal-to-metal
connection to the rack. If you do not use equipment racks, you can attach wiring terminals directly to
the mounting brackets for appropriate grounding. Extreme Networks switches have grounding
terminals that are mounted on the back of the chassis.
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.
● Use the appropriate chassis grounding wire for your system, which is dependant upon the available
input current to the power supply.
■ For AC systems using a 20A breaker per PSU (SSI AC), the chassis ground can be as small as
14 AWG. The power cable ground should be the same size as the primary.
■ For DC systems using a 15A breaker per PSU (Summit X450a-48tDC switch), the chassis
ground can be as small as 14 AWG. The power cable ground should be the same size as the
primary.
■ For DC systems using a 40A breaker per PSU (SSI DC), the chassis ground can be as small as
10 AWG. The power cable ground should be the same size as the primary.
This recommendation does not apply to the Summit family of switches, other than the Summit
X450a-48tDC switch. Other Summit switches do not need separate chassis grounding for AC or DC
systems.
For complete details on power supplies and power supply cords, refer to the following: Chapter 6, “Extreme
Networks Power Supply Units for BlackDiamond Switches,” and “Power Supply Cords Selection” on page 375 in
Appendix A, “Safety Information.” Drill and tap wire terminals to equipment racks.
● 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 insure good grounding between the chassis, rack, and earth ground.
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 24 inches (61 cm) behind the rack. When using a
relay rack, provide a minimum of 24 inches (61 cm) of space behind the mounted equipment. Extra
room on each side is optional.
The chassis does not have a switch for turning power to the unit on and off. For systems using an AC power supply,
power to the chassis is disconnected by removing the wall plug from the electrical outlet. For systems using a DC
SSI power supply, power to the chassis can be turned off by lifting the handle on the power supply or by deenergizing the circuit that feeds the power supply, which is usually accomplished by turning off a circuit breaker.
Power to the Summit X450a-24tDC switch and the EPS-150DC can be turned off be disconnecting the DC wiring
harness from the DC power source only, which requires the performance of a qualified, licensed electrician.
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 4.
Figure 4: Properly secured rack
Brace open distribution racks if the channel thickness is less than 1/4 inch (6.4 mm).

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.
Consider the following recommendations when setting up a cable labeling system suitable for your
installation:
● Identify cables by securely attaching a label 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 distribution 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 distribution rack. Include the following cable drop information: the cable
