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. 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.

 Make sure 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, wear an ESD wrist strap to avoid damaging the units.

Examining the installation site

The switch must be used indoors. You can mount your switch in a rack or on a workbench, but make sure:

 Adequate clearance is reserved at the air inlet and outlet vents for ventilation.  The rack or workbench has a good ventilation system.  The rack is sturdy enough to support the switch and its accessories.  The rack or workbench is reliably grounded.

To ensure correct 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 temperature and humidity in the equipment room in the acceptable range.  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, see "Appendix A Chassis views and technical

specifications."

Cleanliness

Dust buildup on the chassis might 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.

Table 3 Dust concentration limit in the equipment room

The equipment room must also meet limits on salts, acids, and sulfides to eliminate corrosion and premature aging of components, as shown in Table 4.

Table 4 Harmful gas limits in the equipment room

WARNING!

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

EMI

All electromagnetic interference (EMI) sources, from outside or inside of the switch and application system, adversely affect the switch in the following ways:

 A conduction pattern of capacitance coupling.  Inductance coupling.  Electromagnetic wave radiation.  Common impedance (including the grounding system) coupling.

To prevent EMI, perform the following tasks:  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.

Laser safety

The switch is Class 1 laser device.

Installation tools

 Flathead screwdriver  Phillips screwdriver  Needle-nose pliers  Wire-stripping pliers  Diagonal pliers  ESD wrist strap  Blow dryer

All these installation tools are user supplied.

The 5120 24G PoE+ (370W) SI switch comes with a ring terminal for connecting to a grounding strip. For other switch models, you must prepare ring terminals yourself.

To connect the grounding cable, ,follow these steps:

1. Identify the grounding point (with a grounding sign) on the rear panel of the switch chassis, and remove the grounding screw from the grounding point.

2. Attach the grounding screw to the ring terminal of the grounding cable.

3. Use a screwdriver to fasten the grounding screw into the grounding screw hole. Figure 13 Connecting the grounding cable to the grounding hole of the switch chassis

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

5. Cut the grounding cable as appropriate for connecting to the grounding strip.

6. Make the connector for connecting to the grounding strip:

 If a ring terminal is available, peel 5 mm (0.20 in) of insulation sheath by using a wire

stripper, and insert the bare metal part through the black insulation covering into the end of the ring terminal, secure the metal part of the cable to the ring terminal with a crimper, cover the joint with the insulation covering, and heat the insulation covering with a blow dryer to completely cover the metal part (see callout A in Figure 14).

 If no ring terminal is available, peel the insulation sheath as appropriate by using a wire

stripper, and bend the bare metal part into a ring (see callout B in Figure 14).Attach the ring terminal or the ring to the grounding strip through the grounding post, and fasten it with the removed hex nut, see Figure 15.

3. Tighten the screws on the plug with a flat-blade screwdriver to secure the plug in the RPS

receptacle (see callout 2 in Figure 19).

4. Connect the other end of the power cord to the RPS.

5. Make sure the RPS is supplying power and verify that the RPS status LED is ON.

Accessing the switch for the first time

Setting up the configuration environment

The first time you access the switch you must use a console cable to connect a console terminal, for example, a PC, to the console port on the switch.

Figure 20 Connecting the console port to a terminal

Connecting the console cable

Console cable

A console cable is an 8-core shielded cable, with a crimped RJ-45 connector at one end for connecting to the console port of the switch, and a DB-9 female connector at the other end for connecting to the serial port on the console terminal.

Figure 21 Console cable

Connecting the console cable

To connect a terminal, for example, a PC, to the switch:

1. Plug the DB-9 female connector of the console cable to the serial port of the PC.

2. Connect the RJ-45 connector to the console port of the switch.

Page 22

NOTE:

 Identify the mark on the console port and make sure you are connecting to the correct port.  The serial ports on PCs do not support hot swapping. To connect a PC to an operating switch, first

connect the PC end. To disconnect a PC from an operating switch, first disconnect the switch end.

Setting terminal parameters

To configure and manage the switch through the console port, you must run a terminal emulator program, HyperTerminal or PuTTY, on your configuration terminal. You can use the emulator program to connect a network device, a Telnet site, or an SSH site. For more information about the terminal emulator programs, see the user guides for these programs.

The following are the required terminal settings:

 Bits per second—9,600.  Data bits—8.  Parity—None.  Stop bits—1.

Powering on the switch

Before powering on the switch, verify that the following conditions are met:

 The power cord is correctly connected.  The input power voltage meets the requirement of the switch.  The console cable is correctly connected.  The configuration terminal (a PC, for example) has started, and its serial port settings are

consistent with the console port settings on the switch.

Power on the switch. During the startup process, you can access Boot ROM menus to perform tasks such as software upgrade and file management. The Boot ROM interface and menu options differ with software versions. For more information about Boot ROM menu options, see the software-matching release notes for the device.

After the startup completes, you can access the CLI to configure the switch. For more information about the configuration commands and CLI, see the configuration guides and

command references for the switch.

Setting up an IRF fabric

You can use Hewlett Packard Enterprise Intelligent Resilient Framework (IRF) technology to connect and virtualize 5120 SI switches into a virtual switch called an "IRF fabric" or "IRF virtual device" for flattened network topology, and high availability, scalability, and manageability.

Description

1. Plan IRF fabric setup

Plan the installation site and IRF fabric setup parameters:

 Planning IRF fabric size and the installation site  Identifying the master switch and planning IRF member IDs  Planning IRF topology and connections  Identifying physical IRF ports on the member switches  Planning the cabling scheme

2. Install IRF member switches

See "Installing the switch."

3. Connect the grounding cable and power cords

See "Grounding the switch" and "Connecting the power cord."

4. Power on the switches

N/A

5. Configure basic IRF settings

See "Configuring basic IRF settings."

6. Connect the physical IRF ports

See "Connecting the physical IRF ports." All switches except the master switch automatically reboot, and the IRF

fabric is established.

NOTE:

As your business grows, you can plug a switch into an IRF fabric to increase the switching capacity without any topology change or replacement.

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 the IRF configuration guide for your switch.

To set up an IRF fabric:

Planning IRF fabric setup

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.

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.

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.

Page 25

NOTE:

 Figure 23 and Figure 24 show the topologies of a 5120 24G SI IRF fabric.  The IRF port connections in these figures are for illustration only, and more connection methods

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. An IRF port is a logical interface for the internal connection 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 physical ports 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.

You can bind several physical ports to an IRF port to create an aggregate IRF link for increased bandwidth and availability.

Identifying physical IRF ports on the member switches

Identify the physical IRF ports on the member switches according to your topology and connection scheme.

All network ports can be used for IRF connection. As a best practice, use Gigabit SFP ports and HPE 3600 Switch SFP Stacking Kit cables for IRF connection.

Planning the cabling scheme

You can use the GE twisted pair cables, SFP transceiver modules and optical fibers, or SFP Stacking Kit cables to connect the 5120 SI switches for IRF connections. As a best practice, use Gigabit SFP ports and HPE 3600 Switch SFP Stacking Kit cables for IRF connection.

Figure 25 shows two IRF connection schemes and uses Gigabit SFP ports and HPE 3600 Switch

SFP Stacking Kit cables for IRF connection. All these schemes use a ring topology.

Figure 26 shows the IRF fabric topology.

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 the IRF configuration guide for your switch.

Configuring basic IRF settings

After you install the IRF member switches, power on the switches, and log in to each IRF member switch (see the fundamentals configuration guide for your switch) to configure their member IDs, member priorities, and IRF port bindings.

Follow these guidelines when you configure the neighboring 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.  Execute the irf-port-configuration active command to activate the IRF port configuration.  Execute the display irf configuration command to verify the basic IRF settings.

For more information about configuring basic IRF settings, see the IRF configuration guide for your switch.

Connecting the physical IRF ports

Connect the IRF member switches as planned.

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 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 the fundamentals configuration guide for your switch.

4. Verify 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 the table bellow.

Maintenance and troubleshooting

Power supply failure

The 5120 SI switches use built-in power supplies. The 5120 24G PoE+ (370W) SI switch support three power input modes: AC input, RPS DC input, and concurrent AC and RPS DC inputs. All other 5120 SI switches support only AC power input.

To identify a power failure:  On the 5120 24G PoE+ (370W) SI switch, look at the power LED and the RPS status LED of the

switch. For more information, see "LEDs."

 On any other 5120 SI switch, look at the power LED of the switch. For more information, see

"LEDs."

AC input

If the power LED is off, an AC input failure has occurred. Verify the following items:  The AC power cord is securely connected to the switch, and the AC-input power receptacle on

the switch and the connected AC power outlet are in good condition.

 The external AC power system is correctly working.  The operating temperature of the switch is in the normal range, and the power module has good

ventilation. Over-temperature can cause the power module to stop working and enter the protection state.

RPS DC input

If the power LED or RPS status LED is off, an RPS input failure has occurred. Verify the following items:

 The switch is securely connected to the RPS.  The RPS is correctly working.  The operating temperature of the switch is in the normal range, and the power supply has good

ventilation. Over-temperature can cause the power supply to stop working and enter the protection state).

Concurrent RPS and AC inputs

1. If the power LED is off, the AC power supply and the RPS both have an input failure.

Verify the following items:

 The AC power cord is securely connected to the switch, and the AC-input power receptacle

on the switch and the connected AC power outlet are in good condition.

 The external AC power system is correctly working.  The switch is securely connected to the RPS.  The RPS is correctly working.  The operating temperature of the switch is in the normal range, and the power supply has

good ventilation. Over-temperature can cause the power supply to stop working and enter the protection state.

2. If the power LED is on but the RPS status LED is steady yellow, an AC input failure has occurred.

Verify the following items:

 The AC power cord is securely connected to the switch, and the AC-input power receptacle

on the switch and the connected AC power outlet are in good condition.

 The external AC power system is correctly working.

Page 29

NOTE:

If the problem persists, contact the Hewlett Packard Enterprise technical support for help.

3. If the power LED is on but the RPS status LED is off, an RPS input failure has occurred. Verify the following items:

 The switch is securely connected to the RPS.  The RPS is correctly working.

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 would display nothing or garbled text.

No terminal display

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

 The power supply is supplying power to the switch.  The console cable is correctly 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.

The 5120 8G PoE+ (65W) SI, 5120 8G PoE+ (180W) SI, and 5120 24G PoE+ (370W) SI switches also use a port mode LED to indicate the type of information that the port LEDs are displaying (see Table 16).
