Overview of the BlackDiamond 8800 Series Switches

The BlackDiamond switches are chassis-based, Ethernet service core switches designed for core applications.
The features of these switches include:
● Hot-swappable I/O modules that include Gigabit Ethernet copper ports (10/100/1000) and Gigabit
Ethernet fiber ports (SFP), or 10 Gigabit Ethernet ports (XFP)
● Management Switch Fabric Modules (MSMs) that provide the active switching fabric and CPU
control subsystem
● Redundant, load-sharing, hot-swappable power supplies
● Field-replaceable, hot-swappable fan trays
● Auto-negotiation for half-duplex or full-duplex operation on 10/100/1000 Mbps ports
● Load sharing on multiple ports
The BlackDiamond 8800 series switches include two chassis models:
● BlackDiamond 8806 switch
● BlackDiamond 8810 switch
For more information about configuring a BlackDiamond switch, see the ExtremeXOS 12.1 Concepts Guide and the ExtremeXOS 12.1 Command Reference Guide.

About the BlackDiamond 8800 Series Switches

Full-Duplex Support

Extreme Networks switches provide full-duplex support for all ports. Full-duplex support means that frames can be transmitted and received simultaneously, effectively doubling the bandwidth available on a link. Most ports on an Extreme Networks switch will auto-negotiate duplex operation in the default configuration. Gigabit Ethernet fiber ports and 10-Gigabit Ethernet ports operate only in full-duplex mode in accordance with technical standards.

Management Ports

Each BlackDiamond series Management Switch Fabric Module (MSM) has a 10/100BASE-TX Ethernet management port. This port allows you to communicate directly with the central processing unit (CPU) of the switch. You can plug an Ethernet cable directly from your laptop into the management port for direct access into the switch. This access allows you to view and locally manage the switch configurations.

External Compact Flash Memory Card

All MSMs in the BlackDiamond family include a compact flash slot next to the console port. This slot accepts a compact flash memory card, which can be used to download a new version of ExtremeXOS and for other functions, including capturing debug information and core dump files. See the ExtremeXOS 12.1 Concepts Guide for more information regarding the use of the external compact flash memory card.
The external compact flash slot supports third-party compact flash cards.
NOTE
You must use an industrial-grade compact flash card in the external compact flash slot of the MSM.

BlackDiamond 8806 Switch Chassis

The BlackDiamond 8806 chassis includes the following components:
● One 6-slot chassis with backplane
● Four dedicated I/O module slots, labeled 1, 2, 5, and 6
● One dedicated MSM slot, labeled 3/A
● One dual-use slot for either an I/O module or MSM, labeled 4/B
● Power supply bay that accommodates up to six power supplies, accessed from the front of the unit

2 BlackDiamond 8800 Series Modules

This chapter describes modules for the BlackDiamond 8800 series of switches and includes the following sections:
● Overview of the BlackDiamond 8800 Series Modules on page 21
● Management Switch Modules (MSM) on page 21
● I/O Modules on page 25

Overview of the BlackDiamond 8800 Series Modules

Modules available for the BlackDiamond 8800 series switches include management switch modules (MSMs) and I/O modules. A BlackDiamond module consists of a printed circuit board mounted on a metal panel that acts as the insertion vehicle in the BlackDiamond 8800 series switches. The module carrier also includes ejector/injector levers and captive retaining screws at each end of the module front panel. LEDs on the module front panel provide information about the operating status of the modules.
CAUTION
Do not attempt to mix modules across Extreme Networks product lines. BlackDiamond 8800 series modules are for use only in a BlackDiamond 8806 or 8810 switch. When a BlackDiamond 8800 series switch is in use, ExtremeXOS software will not recognize a module from a different product line.

Management Switch Modules (MSM)

The following MSMs are available for the BlackDiamond 8800 series switches:
● MSM-G8X
● MSM-48
● MSM-48c
The MSMs provide the active switching fabric and CPU control subsystem for the switch. One MSM is required for switch operation; however, adding a second MSM to the chassis increases reliability and throughput. Each MSM provides 192 Gbps of switching throughput through three ASICs.
A compact flash slot allows you to insert an external compact flash memory card. (See Chapter 1 for more information about Extreme Networks-supported compact flash cards.)
Redundant MSM Activity
The BlackDiamond 8800 series switches can run with a single MSM installed. When you install an additional MSM, one of the MSMs operates as the primary MSM and the other becomes the backup (secondary) MSM. The primary MSM is responsible for upper-layer protocol processing and system management functions. Packet handling is distributed among the CPUs of all installed MSMs.
When you save the switch configuration, it is saved to all MSMs.
BlackDiamond 8800 Series Switches Hardware Installation Guide
21
Page 22
BlackDiamond 8800 Series Modules
Selection of the primary MSM occurs automatically. The following examples describe the selection process:
● When a switch boots with two MSMs installed, the MSM in the lower-numbered slot becomes the
primary MSM. In the BlackDiamond 8810 switch this is slot 5; in the BlackDiamond 8806 switch, this is slot 3.
● When a switch boots with a single MSM (regardless of the slot position), it is selected as the primary
MSM. If a second MSM is added to the switch after it has been powered up, the added MSM becomes the
backup MSM. MSMs that operate as backup MSMs can be inserted and removed without disrupting network services.
● If you remove the primary MSM while the switch is operating, the backup MSM performs a soft
reset and then becomes the primary MSM. For example, in a BlackDiamond 8810 switch with a primary MSM in slot 5 and a backup MSM in
slot 6, if you remove the primary MSM from slot 5, the backup MSM in slot 6 becomes the primary MSM.

MGMT
The BlackDiamond 8800 series MSMs have the following features on the front panel:
● Console port—DB-9 serial port used to connect a terminal and perform local management.
● Management port—A 10/100 Mbps Ethernet management port used to connect an Ethernet cable
directly from your laptop to the switch to view and locally manage the switch configurations. This port can also be used to connect the system into a parallel management network for administration.
● A button—Allows you to select the alternate BootROM image when you power on the module. To
use the alternate BootROM image, you must hold the A button while pressing the R button simultaneously.
● D button—Allows you to force a system dump that dumps the debug information into NVRAM.
This information is available on the next reboot. No core file is created.
● R button—Allows you to reset the MSM-G8X without removing the module from the chassis.
● Compact flash slot
The MSM-G8X has the following additional ports:
● Eight SFP data ports—These data ports operate the same as the ports on the G24X I/O module. (See
“G24X I/O Module” on page 26 for more information about these ports.) The eight data ports are
integrated into the MSM and managed by a separate I/O processor, which retains control of the eight Ethernet ports on the MSM during a failover. The backup MSM can take control of the ports.
The MSM-48c has a slot for one of the following option cards:
● S-G8Xc—Adds eight 1-gigabit SFP data ports to the MSM-48c. These data ports operate the same as
the ports on the G24Xc I/O module. (See “G24Xc I/O Module” on page 34 for more information about these ports.)
● S-10G1Xc—Adds one 10-gigabit XFP data port to the MSM-48c. This data port operates the same as
the ports on the 10G4Xc I/O module. (See “10G4Xc I/O Module” on page 33 for more information about this port.)
The MSM-48c has more CPU memory than the other two MSM models. For details of feature support in the MSM-48c, see the ExtremeXOS 12.1 Concepts Guide.
NOTE
See the ExtremeXOS 12.1 Concepts Guide and the ExtremeXOS 12.1 Command Reference Guide for more information about numbering conventions for modules and ports, as well as configuration and display information.

I/O Modules

The following series of I/O modules are available for the BlackDiamond 8800 series switches:
● BlackDiamond 8800 original series I/O modules (see page 25)
● BlackDiamond 8800 a-series I/O modules (see page 28)
● BlackDiamond 8800 c-series I/O modules (see page 32)
● BlackDiamond 8800 e-series I/O modules (see page 36)

I/O Modules
No configuration information is stored on the I/O modules; all configuration information is stored on the MSMs.
When a BlackDiamond 8800 series switch is powered on, the software generates a default configuration for any slots that contain I/O modules. The default configuration allows the I/O module ports to participate in the VLAN named default. The default configuration for the I/O module is not preserved unless you explicitly save the configuration to NVRAM.
You can configure parameters of an I/O module after it is installed, or preconfigure a slot for a certain type of module and configuration. The preconfigured information is applied to the module after it is inserted. If you preconfigure a slot for a specific module type and then insert a different type of module, the inserted module reverts to its default configuration.
NOTE
See the ExtremeXOS 12.1 Concepts Guide and the ExtremeXOS 12.1 Command Reference Guide for feature-specific information related to BlackDiamond 8800 series modules.
CAUTION
When BlackDiamond 8800 I/O modules from different series (original series, a-series, c-series, and e-series) are installed in the same BlackDiamond 8800 series chassis, limitations on feature sets may occur. See the ExtremeXOS 12.0 Concepts Guide and the ExtremeXOS 12.0 Command Reference Guide for more information about these limitations.

The chapter describes the power supply units used with the BlackDiamond 8800 series switches.

Overview of BlackDiamond 8800 Series Power Supplies

The BlackDiamond 8800 series switches can be powered by either AC or DC power supplies (PSUs). AC power supplies in the BlackDiamond 8800 series switches are fully fault tolerant and load-sharing in an N+1 configuration. For a switch using DC power supplies in an N+N configuration, each group of power supplies can provide A/B feed redundancy for the system. After the system is properly configured, if one PSU fails, the others will provide sufficient power to operate a fully loaded switch.
The BlackDiamond power supply units are intended for use in specific BlackDiamond switches only.
Table 8 lists the BlackDiamond 8800 series switches and their compatible power supply units.

Combining Different AC PSU Models

Make sure that the 600/900 W AC PSU circuit is not overloaded. Use proper over-current protection, such as a circuit-breaker, to prevent over-current conditions.
Fuse
The Extreme Networks 600/900 W AC PSU line and neutral legs are both fused. Power to the system may still be live if the neutral fuse is open. This is not a field operator replaceable fuse. In the event of failure, immediately return the Extreme Networks 600/900 W AC PSU for a complete replacement.
WARNING!
Field operators must not attempt to configure or replace fuses in Extreme Networks 600/900 W AC PSUs! In the event of failure, immediately return the defective Extreme Networks 600/900 W AC PSU for a complete replacement.
Specifications
The 600/900 W AC PSU functions from 90 V to 264 V and 47 Hz to 63 Hz AC Input. Each PSU provides 600 W to the system if the AC input is in the 110 V low-line output power range and 900 W to the system if the AC input is in the 220 V high-line output power range.
A greater number of PSUs are needed to support the load if the low-line power range is used to power the switch. The software determines the maximum available power required for the switch and enables the modules accordingly.
Combining Different AC PSU Models
When 600/900 W AC PSUs and 700/1200 W AC PSUs are combined in the same BlackDiamond 8806 chassis and are powered on, all PSUs will be budgeted down to the lower powered 600/900 W AC output values to avoid PSU shutdown due to over-current. ExtremeXOS optimizes total system power, avoiding the possibility of over-current, by deciding whether to budget down PSUs with 220 V AC inputs when PSUs with 110 V AC inputs are present, or to keep 110 V AC PSUs disabled.
CAUTION
Even though this process avoids the possibility of over-current, an I/O module may be powered off if a 600/900 W AC PSU is added to a BlackDiamond 8806 system running in the following configuration:
●
The system is powered by three 700/1200 W AC PSUs at 220 V AC.
●
The system includes four or more PoE I/O modules with a PoE power requirement that falls between 2391 W and 2438 W of inline power.
To avoid causing an I/O module to be powered off, do not add a 600/900 W AC PSU to an existing BlackDiamond 8806 system running in the configuration listed above. Extreme Networks also recommends that you avoid mixing 220 V AC and 110 V AC inputs when both 600/900 W and 700/1200 W PSUs are present in the same system. When a combination of 220 V AC and 110 V AC inputs is applied, ExtremeXOS is designed to optimize total chassis power for each individual PSU type but not for a mixture of PSU types.

4 Site Preparation

This chapter includes the following sections:
● Planning Your Site on page 53
● Meeting Site Requirements on page 54
● Evaluating and Meeting Cable Requirements on page 60
● Meeting Power Requirements on page 66
● Applicable Industry Standards on page 68
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 system 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.
To learn more about safety issues and to ensure safety compliance, see Appendix A.
NOTE
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.

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 power supply unit installed in the system. For power supply specifications, see “Power Supplies for
BlackDiamond 8800 Series Switches” on page 172.

Meeting Site Requirements

This section describes 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. The following sections are provided as a resource to obtain 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.
http://www.iccsafe.org
http://www.sbcci.org
Five authorities on electrical codes are:

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 58 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 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.
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).
BlackDiamond 8800 Series Switches Hardware Installation Guide
55
Page 56
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.
Chassis Spacing Requirements
Extreme Networks recommends placing no more than three BlackDiamond chassis next to each other because of to chassis-to-chassis heating. Use the following spacing guidelines when you install your BlackDiamond 8800 series switch:
● Leave a minimum of one empty 19-inch rack between two sets of three adjacent BlackDiamond
switches. or
● Place patch panels between two sets of three adjacent BlackDiamond switches. A patch panel does
not require any power and does not generate any heat.
NOTE
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.
Chassis Airflow Requirements
To ensure proper airflow through a BlackDiamond switch, refer to the following recommendations when you install the switch:
● BlackDiamond 8800 series 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).
In the BlackDiamond 8800 series switches, air moves through the power supplies independently of the airflow through the modules, as shown in Figure 28.

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 and the ESD-preventive wrist strap that is provided with your
equipment. All switches have ESD-preventive wrist strap connectors and are shipped with an ESD­preventive wrist strap as shown in Figure 29.

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.
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.
58
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.
BlackDiamond 8800 Series Switches Hardware Installation Guide
Page 59
Meeting Site Requirements
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.
NOTE
For complete details on power supplies and power supply cords, refer to the following: Chapter 3, “Power Supply
Units for BlackDiamond 8800 Series Switches,” and “Selecting Power Supply Cords” on page 158 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.
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 24 inches (61 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!
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.
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 30.

Evaluating and Meeting Cable Requirements

This section describes 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

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.
BlackDiamond 8800 Series Switches Hardware Installation Guide
Page 61
Evaluating and Meeting Cable Requirements
● 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
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 31.
● Bundle cable using velcro straps to avoid injuring cables.
● If you build your own cable, be sure that cable is 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.
● 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.
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.

Evaluating and Meeting Cable Requirements
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 32.
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 33 shows examples of connector jacket types that are not recommended, as well as those that are

Evaluating and Meeting Cable Requirements
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 Cable Requirements
● 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 must use a low-voltage power distribution system per IEEE 802.3af.
Power Supply Requirements
Adhere to the following requirements to operate your Extreme Networks equipment safely:
● Be sure that your equipment is placed in an area that accommodates the power consumption and
component heat dissipation specifications.
● Be sure that your power supply meets the site power or AC power requirements of the network
equipment.
● When connecting power to installed equipment, avoid connecting through an extension cord or
power strip.
● If your switch includes more than one power supply, connect each power supply to different,
independent power sources. 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.
For power specifications of the BlackDiamond power supplies, see Appendix B, “Technical
Specifications.”
66
BlackDiamond 8800 Series Switches Hardware Installation Guide
Page 67
Meeting Power Requirements
AC Power Cable Requirements
Use an AC power cable appropriate for your country. Check your local electrical codes and regulatory agencies for power cable requirements. The countries listed in Table 13 have additional requirements as listed in the table.
Table 13: AC Power Cable Requirements
Country Requirements
USA and Canada • The cable set must be UL-approved and CSA-certified.
2
• The minimum specification for the flexible cable is No. 18 AWG (1.5 mm Type SVT or SJT, 3-conductor.
• The cable set must have a rated current capacity of at least the amount rated for each specific product.
• The attachment plug must be either an Earth-grounding type with a NEMA 5-15P (10 A, 110 V) configuration or a NEMA L6-15P (10 A, 208/240 V)
Denmark The supply plug must comply with section 107-2-D1, standard DK2-1a or DK2-5a.
Switzerland The supply plug must comply with SEV/ASE 1011.
Argentina The supply plug must comply with Argentinian standards.
),
NOTE
When using dual power supplies, make sure that each AC power supply attaches to an independent power source.
Replacing the Power Cable
If the power cable plug is unsuitable and must be replaced, connect the power supply wires for the switch according to the following scheme:
● Brown wire to the Live (Line) plug terminal, which may be marked with the letter “L” or colored
red.
● Blue wire to the Neutral plug terminal, which may be marked with the letter “N” or colored black.
● Yellow/Green wire to the Ground plug terminal, which may be marked with the letter “E” (the
Earth symbol) or colored yellow/green.
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 some time after a blackout has occurred.
In addition, some UPS or UPS plus software combinations provide the following functions:
● Automatically shut down equipment during long power outages.
BlackDiamond 8800 Series Switches Hardware Installation Guide
67
Page 68
Site Preparation
● 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 your installation will allow?
NOTE
Extreme Networks recommends that you use a UPS that provides online protection.
Calculating Volt-Amperage Requirements
To determine the minimum volt-amperage requirements for your UPS: 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.
2 Multiply the numbers together to get Volt-Amps (VA):
VA = Volts x Amp e res
3 Add together the VA from all the pieces of equipment to find the total VA requirement.
To determine the minimum volt-amperage requirements for your UPS, we recommend 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.

● Safety on page 87
● PSU Compatibility on page 88
● Installing an Extreme Networks AC PSU on page 90
● Installing an Extreme Networks 1200 W DC PSU on page 94
The chapter describes how to install and remove each power supply model used with the BlackDiamond 8800 series switches.

Safety

Only trained service personnel should perform service to Extreme Networks switches and their components. Trained service personnel have read all related installation manuals, have the technical training and experience necessary to be aware of the hazards to which they are exposed in performing a task, and are aware of measures to minimize the danger to themselves or other persons.
Before installing an Extreme Networks PSU into your network:
● Read the latest installation and safety information provided in this chapter and in Appendix
A, “Safety Information.”
● See Appendix A, “Safety Information” for additional information regarding regulatory compliance
certifications.
NOTE
For central DC power connections, the 1200 W DC PSU is intended to be installed only in restricted access locations (dedicated equipment rooms, equipment closets, or the like) in accordance with Articles 110-16, 110-17, and 110-18 of the National Electric Code, ANSI/NFPA-70. All wiring methods involving the DC input cable assembly must be performed according to the relevant articles of the National Electrical Code.
CAUTION
Building codes vary worldwide; therefore, Extreme Networks strongly recommends that you consult an electrical contractor to ensure proper equipment grounding and power distribution for your specific installation.
WARNING!
Field operators must not attempt to open the PSU enclosure for any reason; the PSU does not contain user-serviceable parts. In the event of failure, return the defective PSU to Extreme Networks for repair or replacement.
BlackDiamond 8800 Series Switches Hardware Installation Guide

Page 88
Installing Power Supply Units in the BlackDiamond 8800 Series Switches
WARNING!
Extreme Networks AC PSUs do not have switches for turning the unit on and off. Remove the wall plug from the electrical outlet to disconnect the power to an Extreme Networks AC PSU. Make sure that this connection is easily accessible.
When the PSU is outside the chassis (not installed), do not plug the PSU into an electrical outlet. Plugging an uninstalled AC PSU into an electrical outlet exposes you to a hazardous energy and is a potential fire hazard.
WARNING!
Extreme Networks DC PSUs do not have switches for turning the unit on and off. Make sure that the DC circuit is de-energized before connecting or disconnecting the DC power cord at the DC power socket on an Extreme Networks DC PSU.

The 700/1200 W AC PSU and the 600/900 W AC PSU can be used together in the same BlackDiamond 8806 system only.
Extreme Networks does not recommended using the 600/900 W AC PSU or the 700/1200 W AC PSU in combination with a 1200W DC PSU.
Extreme Networks does not recommended using the 700/1200 W AC PSU in combination with a 1200W DC PSU.
Combining Different AC PSU Models
When 600/900 W AC PSUs and 700/1200 W AC PSUs are combined in the same BlackDiamond 8806 chassis and are powered on, all PSUs will be budgeted down to the lower-powered 600/900 W AC output values to avoid PSU shutdown due to over-current.
ExtremeXOS optimizes total system power, avoiding the possibility of over-current, by deciding whether to budget down PSUs with 220 V AC inputs when PSUs with 110 V AC inputs are present, or to keep 110 V AC PSUs disabled.
88
CAUTION
Even though this process avoids the possibility of over-current, an I/O module may be powered off if a 600/900 W AC PSU is added to a BlackDiamond 8806 system running in the following configuration:
●
The system is powered by three 700/1200 W AC PSUs at 220 V AC.
●
The system includes four or more PoE I/O modules with a PoE power requirement that falls between 2391 W and 2438 W of inline power.

Power Supply Cords for AC Power Supplies

To avoid causing an I/O module to be powered off, do not add a 600/900 W AC PSU to an existing BlackDiamond 8806 system running in the configuration listed above. Extreme Networks also recommends that you avoid mixing 220 V AC and 110 V AC inputs when both 600/900 W and 700/1200 W PSUs are present in the same system. When a combination of 220 V AC and 110 V AC inputs is applied, ExtremeXOS is designed to optimize total chassis power for each individual PSU type but not for a mixture of PSU types.
NOTE
Extreme Networks does not recommended using the 1200 W DC PSU in combination with any Extreme Networks AC PSU in the same BlackDiamond 8800 series system. Extreme Networks recommends that DC and AC PSU units not be used together in the same BlackDiamond switch.
Minimum Software Requirements
In order for the system to recognize an Extreme Networks 600/900 W AC PSU, the MSM installed in your BlackDiamond 8806 switch requires ExtremeXOS version 11.6.1 (or later). In ExtremeXOS releases
11.3.4, 11.4.2, and 11.5.1, the 600/900 W AC PSU is disabled on all chassis. In ExtremeXOS releases earlier than those, the software does not recognize the 600/900 W AC PSU and the PSU will not be budgeted properly, possibly resulting in PSU shutdown and/or chassis reboot.
The 700/1200 W AC PSU is supported by all versions of ExtremeXOS.
For the system to recognize the 1200W DC PSU, the MSM in your BlackDiamond 8800 series switch must be running ExtremeXOS version 11.3 or later.
