    Preparing for installation

    Safety recommendations

    To avoid any equipment damage or bodily injury caused by improper use, read the following safety

    recommendations before installation. Note that the recommendations do not cover every possible

    hazardous condition.

    • Before cleaning the switch, unplug all power cords from the switch. Do not clean the switch with wet

    cloth or liquid.

    • Do not place the switch near water or in a damp environment. Prevent water or moisture from

    entering the switch chassis.

    • Do not place the switch on an unstable case or desk. The switch might be severely damaged in case

    of a fall.

    • Ensure proper ventilation of the equipment room and keep the air inlet and outlet vents of the switch

    free of obstruction.

    • Connect the yellow-green protection grounding cable before power-on.

    • Make sure that the operating voltage is in the required range.

    • To avoid electrical shocks, do not open the chassis while the switch is operating or when the switch

    is just powered off.

    • When replacing FRUs, including power supplies and fan trays, wear an ESD-preventive wrist strap

    to avoid damaging the units.

    Examining the installation site

    The HP 5920AF-24XG and 5900AF-48XG-4QSFP+ switches must be used indoors.

    Mount your switch in a rack and make sure:

    • Adequate clearance is reserved at the air inlet and exhaust vents for ventilation.

    • The rack has a good ventilation system.

    • Identify the hot aisle and cold aisle at the installation site, and make sure that ambient air flows into

    the switch from the cold aisle and exhausts to the hot aisle.

    • Identify the airflow designs of neighboring devices, and prevent hot air flowing out of the bottom

    device from entering the top device.

    • The rack is sturdy enough to support the switch and its accessories.

    • The rack is well earthed.

    To ensure normal operation and long service life of your switch, install it in an environment that meets the

    requirements described in the following subsections.

    Temperature/humidity

    Maintain appropriate temperature and humidity in the equipment room.

  • Page 9:

    5

    • Lasting high relative humidity can cause poor insulation, electricity creepage, mechanical property

    change of materials, and metal corrosion.

    • Lasting low relative humidity can cause washer contraction and ESD and bring problems including

    loose captive screws and circuit failure.

    • High temperature can accelerate the aging of insulation materials and significantly lower the

    reliability and lifespan of the switch.

    For the temperature and humidity requirements of different switch models, see “Appendix A Technical

    spec

    ifications.”

    Cleanness

    Dust buildup on the chassis may result in electrostatic adsorption, which causes poor contact of metal

    components and contact points, especially when indoor relative humidity is low. In the worst case,

    electrostatic adsorption can cause communication failure.

    Dust

    ≤ 3 x 10

    4

    (no visible dust on the tabletop over three days)

    NOTE:

    Dust diameter ≥ 5 μm

    The equipment room must also meet strict limits on salts, acids, and sulfides to eliminate corrosion and

    premature aging of components, as shown in Table 3.

    EMI

    All electromagnetic interference (EMI) sources, from outside or inside of the switch and application

    system, adversely affect the switch in a conduction pattern of capacitance coupling, inductance coupling,

    electromagnetic wave radiation, or common impedance (including the grounding system) coupling. To

    prevent EMI, take the following actions:

    • If AC power is used, use a single-phase three-wire power receptacle with protection earth (PE) to

    filter interference from the power grid.

    • Keep the switch far away from radio transmitting stations, radar stations, and high-frequency

    devices.

    • Use electromagnetic shielding, for example, shielded interface cables, when necessary.

    • Route interface cables only indoors to prevent signal ports from getting damaged by overvoltage or

    overcurrent caused by lightning strikes.

  • Page 10:

    Laser safety

    The HP 5920 and 5900 series switches are Class 1 laser devices.

    W

    ARNING!

    Do not stare into any fiber port when the switch has power. The laser light emitted from the optical fiber

    may hurt your eyes.

    Installation tools

    • Phillips screwdriver

    • ESD-preventive wrist strap

    All these installation tools are user supplied.

    Installing the switch

    CAUTION:

    Keep the tamper-proof seal on a mounting screw on the chassis cover intact, and if you want to open the

    chassis, contact HP for permission. Otherwise, HP shall not be liable for any consequence caused thereby.

    Attaching the mounting brackets and chassis rails to the chassis

    To attach the mounting brackets and chassis rails to the switch chassis:

    1. Align the mounting brackets with the screw holes in the rear mounting position (see Figure 13) or

    front mounting position (see Figure 14).

    2. Use M4 screws (supplied with the switch) to attach the mounting brackets to the chassis.

    3. Align the chassis rails with the rail mounting holes in the chassis:

    { If the mounting brackets are in the rear mounting position, align the chassis rails with the screw

    holes at the front of the side panels (see Figure 13).

    { If the mounting brackets are in the front mounting position, align the chassis rails with the screw

    holes at the rear of the side panels (see Figure 14).

    4. Use M4 screws (supplied with the switch) to attach the chassis rails to the chassis.

    NOTE:

    Secure the mounting brackets and chassis rails to both sides of the chassis in the same way.

    Connecting the grounding cable to the chassis

    CAUTION:

    The primary grounding point and auxiliary grounding point 1 are located on the left side panel. If you use

    one of these grounding points, you must connect the grounding cable to the grounding point before you

    mount the switch in the rack.

    NOTE:

    • HP recommends that you use the primary grounding point or auxiliary grounding point 1 because the

    grounding cable and grounding screw that come with the switch are suitable only for these two

    grounding points.

    • To use auxiliary grounding point 2 on the HP 5900AF-48XG-4QSFP+ switch, you must prepare a

    grounding cable yourself.

    To connect the grounding cable to a chassis grounding point, for example, the primary grounding point:

    1. Choose a grounding point.

    2. Unpack the grounding cable and grounding screws.

    You can use the cable and screws shipped with the switch only for connecting to the primary

    grounding point or auxiliary grounding point 1.

    3. Align the two-hole grounding lug at one end of the cable with the grounding holes of the

    grounding point, insert the grounding screws into the holes, and tighten the screws with a

    screwdriver to attach the grounding lug to the chassis, as shown in Figure 13.

    Attaching the slide rails to the rack

    To attach the slide rails to the rack:

    1. Identify the rack attachment position for the slide rails.

    2. Install cage nuts (user-supplied) in the mounting holes in the rack posts.

    3. Align the screw holes in one slide rail with the cage nuts in the rack post on one side, and use

    screws (user supplied) to attach the slide rail to the rack, as shown in Figure 15.

    4. Repeat the preceding step to attach the other slide rail to the rack post on the other side.

    Keep the two slide rails at the same height so the slide rails can attach into the chassis rails.

    Figure 15 Installing the slide rails

    Mounting the switch in the rack

    This task requires two people. To mount the switch in the rack:

    1. Wear an ESD-preventive wrist strap and make sure it makes good skin contact and is well

    grounded.

    2. Check that the mounting brackets and chassis rails have been securely attached to the switch

    chassis.

    3. Check that the slide rails have been correctly attached to the rear rack posts.

    4. Install cage nuts (user-supplied) to the front rack posts and make sure they are at the same level as

    the slide rails.

    5. Supporting the bottom of the switch, align the chassis rails with the slide rails on the rack posts, as

    shown in Figure 16. Work with another person to slid

    e the chassis rails along the slide rails until

    the mounting brackets are flush with the rack posts.

    6. Use screws (user-supplied) to attach the mounting brackets to the rack, as shown in Figure 17.

    To secure the switch in the rack, make sure that the front ends of the slide rails reach out of the

    chassis rails.

    Grounding the switch

    W

    ARNING!

    Correctly connecting the switch grounding cable is crucial to lightning protection and EMI protection.

  • Page 18:

    14

    The power input end of the switch has a noise filter, whose central ground is directly connected to the

    chassis to form the chassis ground (commonly known as PGND). You must securely connect this chassis

    ground to the earth so the faradism and leakage electricity can be safely released to the earth to

    minimize EMI susceptibility of the switch.

    You can ground a switch by using a grounding strip at the installation site or the AC power cord

    connected to the switch.

    NOTE:

    The power and grounding terminals in this section are for illustration only.

    Grounding the switch with a grounding strip

    W

    ARNING!

    Connect the grounding cable to the grounding system in the equipment room. Do not connect it to a fire

    main or lightning rod.

    If a grounding strip is available at the installation site, connect the grounding cable to the grounding

    strip.

    To connect the grounding cable:

    1. Attach the two-hole grounding lug at one end of the grounding cable to a grounding point on the

    switch chassis (see “Connecting the grounding cable to the chassis”).

    2. Remove the hex nut of a grounding post on the grounding strip.

    3. Attach the OT terminal at the other end of the grounding cable to the grounding strip through the

    grounding post, and fasten the OT terminal with the removed hex nut.

    Grounding the switch by using the AC power cord

    If the installation site has no grounding strips, you can ground an AC-powered switch through the

    protective earth (PE) wire of the power cord, but must make sure:

    • The power cord has a PE terminal.

    • The ground contact in the power outlet is securely connected to the ground in the power distribution

    room or on the AC transformer side.

    • The power cord is securely connected to the power outlet.

    NOTE:

    If the

    Installing/removing a power supply

    W

    ARNING!

    In power redundancy mode, you can replace a power supply without powering off the switch but must

    strictly follow the installation and procedures in Figure 22 and Figure 23 to avoid a

    ny bodily injury or

    damage to the switch.

    The switches do not support intermixing of AC and DC power supplies.

    The HP 5920AF-24XG and 5900AF-48XG-4QSFP+ switches come with both power supply slots empty

    and the power filler modules as accessories.

    You can install one or two power supplies for these switches as needed. For more information about the

    power supplies available for the switches, see “Hot swappable power supplies.”

    NOTE:

    The HP A58x0AF 650W AC power supply and the HP A58x0AF 650W DC power supply are referred to

    as the 650W AC power supply and the 650W DC power supply throughout this installation guide.

    Installing a power supply

    CAUTION:

    • Follow the forward inertia of the power supply when inserting it into the chassis, and make sure that the

    power supply has firm contact with the connectors on the backplane.

    • To prevent damage to the connectors inside the switch chassis, insert the power supply gently. If you

    encounter a hard resistance while inserting the power supply, pull out the power supply and insert it

    again.

    • If only one power supply is installed, install a power filler module in the empty power supply slot for

    good ventilation of the switch.

    To install a 650W AC power supply or 650W DC power supply into the switch:

    1. Wear an ESD-preventive wrist strap and make sure it makes good skin contact and is well

    grounded.

    2. Unpack the power supply and check that the power supply model is correct.

    3. Correctly orient the power supply with the power supply slot (see Figure 24), grasp the handle of

    the power supply with one hand and support its bottom with the other, and slide the power supply

    slowly along the guide rails into the slot.

    The slot is foolproof. If you cannot insert the power supply into the slot, re-orient the power supply

    rather than use excessive force to push it in.

    Setting up an IRF fabric

    You can use HP IRF technology to connect and virtualize HP 5920 and 5900 switches into a large virtual

    switch called an “IRF fabric” for flattened network topology, and high availability, scalability, and

    manageability.

    To set up IRF links between HP 5920 and 5900 series switches, use SFP+ ports or QSFP+ ports.

    Connect the physical IRF ports on switches. Use SFP+ or QSFP+ transceiver

    modules and fibers for long-distance connection. Use SFP+ or QSFP+ cables for

    short-distance connection.

    All switches except the master switch automatically reboot, and the IRF fabric is

    established.

    Planning IRF fabric setup

    This section describes issues that an IRF fabric setup plan must cover.

    Planning IRF fabric size and the installation site

    Choose switch models and identify the number of required IRF member switches, depending on the user

    density and upstream bandwidth requirements. The switching capacity of an IRF fabric equals the total

    switching capacities of all member switches.

    Plan the installation site depending on your network solution, as follows:

    • Place all IRF member switches in one rack for centralized high-density access.

    • Distribute the IRF member switches in different racks to implement the top-of-rack (ToR) access

    solution for a data center.

    NOTE:

    • As your business grows, you can plug an HP 5920 or 5900 switch into an IRF fabric to increase the

    switching capacity without any topology change or replacement.

    Identifying the master switch and planning IRF member IDs

    Determine which switch you want to use as the master for managing all member switches in the IRF fabric.

    An IRF fabric has only one master switch. You configure and manage all member switches in the IRF

    fabric at the command line interface of the master switch.

    NOTE:

    IRF member switches will automatically elect a master. You can affect the election result by assigning a

    high member priority to the intended master switch. For more information about master election, see

    H

    P

    5920 & 5900 Switch Series IRF Configuration Guide

    .

  • Page 38:

    34

    Prepare an IRF member ID assignment scheme. An IRF fabric uses member IDs to uniquely identify and

    manage its members, and you must assign each IRF member switch a unique member ID.

    Planning IRF topology and connections

    You can create an IRF fabric in daisy chain topology, or more reliably, ring topology. In ring topology,

    the failure of one IRF link does not cause the IRF fabric to split as in daisy chain topology. Rather, the IRF

    fabric changes to a daisy chain topology without interrupting network services.

    You connect the IRF member switches through IRF ports, the logical interfaces for the connections

    between IRF member switches. Each IRF member switch has two IRF ports: IRF-port 1 and IRF-port 2. To

    use an IRF port, you must bind at least one physical port to it.

    When connecting two neighboring IRF member switches, you must connect the physical ports of IRF-port

    1 on one switch to the physical ports of IRF-port 2 on the other switch.

    The HP 5900AF-48XG-4QSFP+ switch can provide 10-GE and 40-GE IRF connections through SFP+

    ports and QSFP+ ports, respectively. You can bind several SFP+ or QSFP+ ports to an IRF port for

    increased bandwidth and availability.

    The HP 5920AF-24XG switch can provide 10-GE IRF connections through SFP+ ports. You can bind

    several SFP+ ports to an IRF port for increased bandwidth and availability.

    NOTE:

    • Figure 38 an

    d Figure 39 show the topologies of an IRF fabric made up of three HP

    5900AF-48XG-4QSFP+ switches that use SFP+ ports for IRF connections.

    • The IRF port connections in the two fi

    g

    ures are for illustration only, and more connection methods are

    available.

    Figure 39 IRF fabric in ring topology

    Identifying physical IRF ports on the member switches

    Identify the SFP+ or QSFP+ ports to be used for IRF connections on the member switches according to

    your topology and connection scheme.

    The HP 5920 and 5900 series switches do not have any IRF port binding restriction. You can bind any

    SFP+ or QSFP+ port on the switch chassis to any IRF port.

    Planning the cabling scheme

    Use SFP+/QSFP+ cables or SFP+/QSFP+ transceiver modules and fibers to connect the IRF member

    switches. If the IRF member switches are far away from one another, choose the SFP+/QSFP+ transceiver

    modules with optical fibers. If the IRF member switches are all in one equipment room, choose

    SFP+/QSFP+ cables. For more information available SFP+/QSFP+ cables and transceiver modules, see

    “SFP+ port” and “QSFP+ port.”

    T

    he following subsections describe several HP recommended IRF connection schemes, and all these

    schemes use a ring topology.

    Connecting the IRF member switches in one rack

    Use short-haul and long-haul SFP+ cables to connect the IRF member switches (four switches in this

    example) in a rack as shown in Figure 40. T

    he switches in the ring topology (see Figure 41) are in the

    same order as connected in the rack.

    Configuring basic IRF settings

    After you install the IRF member switches, power on the switches, and log in to each IRF member switch

    (see HP 5920 & 5900 Switch Series Fundamentals Configuration Guide) to configure their member IDs,

    member priorities, and IRF port bindings.

    Follow these guidelines when you configure the switches:

    • Assign the master switch higher member priority than any other switch.

    • Bind physical ports to IRF port 1 on one switch and to IRF port 2 on the other switch. You perform

    IRF port binding before or after connecting IRF physical ports depending on the software release.

    • To bind the ports on an interface card to an IRF port, you must install the interface card first. For how

    to install an interface card, see HP 5920 & 5900 Switch Series Interface Cards User Guide.

    • Execute the display irf configuration command to verify the basic IRF settings.

    For more information about configuring basic IRF settings, see HP 5920 & 5900 Switch Series IRF

    Configuration Guide.

    Connecting the physical IRF ports

    Use SFP+/QSFP+ cables or SFP+/QSFP+ transceiver modules and fibers to connect the IRF member

    switches as planned.

    NOTE:

    ear an ESD-preventive wrist strap when you connect SFP+ cables or SFP+ transceiver modules and

    fibers. For how to connect them, see

    SFP/SFP+/XFP Transceiver Modules Installation Guide and QSFP+

    Transceiver Modules/Cables Installation Guide

    .

    Accessing the IRF fabric to verify the configuration

    To verify the basic functionality of the IRF fabric after you finish configuring basic IRF settings and

    connecting IRF ports:

    1. Log in to the IRF fabric through the console port of any member switch.

    2. Create a Layer 3 interface, assign it an IP address, and make sure that the IRF fabric and the

    remote network management station can reach each other.

    3. Use Telnet, web, or SNMP to access the IRF fabric from the network management station. (See HP

    5920 & 5900 Switch Series Fundamentals Configuration Guide.)

    4. Check that you can manage all member switches as if they were one node.

    5. Display the running status of the IRF fabric by using the commands in Table 5.

    NOTE:

    To avoid IP address collision and network problems, configure at least one multi-active detection (MAD)

    mechanism to detect the presence of multiple identical IRF fabrics and handle collisions. For more

    information about MAD detection, see

    Power supply failure

    You can use the LEDs on the power supply to identify a power supply failure. For more information about

    the LEDs on a power supply, see HP A58x0AF 650W AC (JC680A) & 650W DC (JC681A) Power

    Supplies User Guide.

    The LEDs on the power supply are steady green (active) or blinking green (standby) while the power

    supply system is correctly working. If the LEDs behave in any other way, verify the following items:

    • The switch power cord is properly connected.

    • The power source meets the requirement.

    • The operating temperature of the switch is in the normal range and the power supply has good

    ventilation.

  • Page 44:

    40

    NOTE:

    If the problem persists, contact the HP technical support for help.

    To replace a hot swappable power supply, see “Installing/removing a power supply.”

    Fan failure

    CAUTION:

    The HP 5920AF-24XG and 5900AF-48XG-4QSFP+ switches require two same direction air flow fan

    trays to function properly.

    • Do not operate the system with only one fan tray for more than 24 hours.

    • Do not operate the system without any fan tray for more than 2 minutes.

    • Do not operate the system outside of the temperature range 0°C to 45°C (32°F to 113°F) degrees.

    Failure to comply with these operating requirements may void the warranty.

    When a fan tray has problems, the system status LED is steady red and the system outputs alarm

    messages.

    To replace a failed fan tray, see “Installing/removing a fan tray.”

    Configuration terminal problems

    If the configuration environment setup is correct, the configuration terminal displays booting information

    when the switch is powered on. If the setup is incorrect, the configuration terminal displays nothing or

    garbled text.

    No terminal display

    If the configuration terminal displays nothing when the switch is powered on, verify the following items:

    • The power supply is supplying power to the switch.

    • The console cable is properly connected.

    • The console cable has no problem and the terminal settings are correct.

    Garbled terminal display

    If terminal display is garbled, verify that the following settings are configured for the terminal, for

    example, HyperTerminal:

    • Baud rate—9,600

    • Data bits—8

    • Parity—none

    • Stop bits—1

    • Flow control—none

    • Emulation—VT100

    Appendix D Cooling system

    The cooling system of HP 5920AF-24XG and 5900AF-48XG-4QSFP+ switches comprises the ventilation

    holes in the chassis, fan trays, and built-in fans of hot swappable power supplies. To guarantee that this

    cooling system can effectively work, you must consider the site ventilation design when you plan the

    installation site for the switches.

    HP 5920AF-24XG cooling system

    The fan trays in the HP 5920AF-24XG switch must be the same type: LSVM124SFAN or LSVM224SFAN.

    • When LSVM124SFAN fan trays are used, cool air flows in through the air vents in the fan tray panel

    and the power supply panels, circulates through the chassis and the power supplies, and exhausts

    at the network port side, as shown in Figure 48.
