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, remove 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 good 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 the operating voltage is in the required range.

· To avoid electrical shocks, do not open the chassis while the switch is operating.

· To avoid damage caused by improper operation, do not open the chassis even if the switch is powered off.

· When replacing power modules, wear an ESD wrist strap to avoid damaging the units.

Examining the installation site

The S5150-EI switches 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.

· Identify the hot aisle and cold aisle at the installation site, and make sure 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 neighboring device from entering the device.

· 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 as described in "Appendix A Chassis views and technical specifications."

· Lasting high relative humidity can cause poor insulation, electricity leakage, 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 "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.

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

WARNING!

The switch is Class 1 laser device. Do not stare into any fiber port when the switch has power. The laser light emitted from the optical fiber might hurt your eyes.

Installation tools

No installation tools are provided with the switch. Prepare the following tools yourself:

· Flat-blade screwdriver

· Phillips screwdriver

· ESD wrist strap

Grounding the switch

WARNING!

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

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 the switch in one of the following ways, depending on the grounding conditions available at the installation site:

· Grounding the switch with a grounding strip

· Grounding the switch with a grounding conductor buried in the earth ground

NOTE:

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

Grounding the switch with a grounding strip

WARNING!

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.

Connecting the grounding cable to the chassis

1. Remove the grounding screw from the rear panel of the switch chassis.

2. Use the grounding screw to attach the ring terminal of the grounding cable to the grounding screw hole.

Figure 15 Connecting the grounding cable to the chassis

(1) Grounding cable	(2) Grounding hole
(3) Grounding sign	(4) Ring terminal
(5) Grounding screw

3. Verify that the grounding cable has been securely connected to the rear grounding point.

Connecting the grounding cable to a grounding strip (S5150-24S-PWR-EI)

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

2. Cut the grounding cable to a length required for connecting to the grounding strip.

3. Attach a ring terminal to the grounding cable:

a. Use a wire stripper to strip 5 mm (0.20 in) of insulation off the end of the grounding cable.

b. Slide the heat-shrink tubing onto the cable and insert the bare metal part into the end of the ring terminal.

c. Use a crimper to secure the metal part of the cable to the ring terminal.

d. Slide the heat-shrink tubing down the cable until the tube covers the joint.

e. Use a heat gun to shrink the tubing around the cable.

Figure 16 Attaching a ring terminal to the grounding cable

4. Connect the ring terminal to the grounding post of the grounding strip, and fasten it with the removed hex nut.

Setting terminal parameters

To configure and manage the switch through the console port, you must run a terminal emulator program, TeraTermPro or PuTTY, on your PC. 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.

· Flow control—None.

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 PC 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 H3C S5150-EI Switch Series Configuration Guides and H3C S5150-EI Switch Series Command References.

Setting up an IRF fabric

You can use H3C IRF technology to connect and virtualize S5150-EI switches into a large virtual switch called an "IRF fabric" for flattened network topology, and high availability, scalability, and manageability.

IRF fabric setup flowchart

Figure 41 IRF fabric setup flowchart

To set up an IRF fabric:

Step	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 in a 19-inch rack" or "Mounting the switch on a workbench."
3. Connect ground wires 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 H3C S5150-EI Switch Series IRF Configuration Guide.
6. Connect the physical IRF ports	Connect physical IRF ports on switches. Use SFP+ transceiver modules and fibers over a long distance, or use SFP+ network cables or twisted pair cables over a short distance. 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 ToR access solution for a data center.

NOTE:

For the maximum IRF member devices supported by the S5150-EI, see the release notes that come with the switch.

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 CLI of the master switch. IRF member switches 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 H3C S5150-EI Switch Series IRF Configuration Guide.

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 reliable ring topology. In ring topology, the failure of one IRF link does not cause the IRF fabric to split as in daisy chain topology. Instead, 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 a minimum of 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 S5150-EI switches can provide 10-GE IRF connections through 1/10GBASE-T Ethernet ports/SFP+ ports, and you can bind several 1/10GBASE-T Ethernet ports/SFP+ ports to an IRF port for increased bandwidth and availability.

Figure 42 and Figure 43 show the topologies of an IRF fabric made up of three S5150X-16S-EI switches. The IRF port connections in the two figures are for illustration only, and more connection methods are available.

Figure 42 IRF fabric in daisy chain topology

Figure 43 IRF fabric in ring topology

Identifying physical IRF ports on the member switches

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

Table 7 shows the physical ports that can be used for IRF connection and the port use restrictions.

Table 7 Physical IRF port requirements

Chassis	Candidate physical IRF ports	Requirements
S5150X-16S-EI	16 fixed SFP+ ports on the front panel	All physical ports to be bound to an IRF port must be the same type.
S5150X-16ST-EI	4 fixed SFP+ ports and 12 fixed 1/10GBASE-T autosensing Ethernet ports on the front panel
S5150-24S-PWR-EI	4 fixed SFP+ ports on the front panel

Planning the cabling scheme

Use twisted pair cables, SFP+ network cables, or SFP+ transceiver modules and fibers to connect the IRF member switches. If the IRF member switches are far away from one another, choose SFP+ transceiver modules with optical fibers. If the IRF member switches are all in one equipment room, choose twisted pair cables or SFP+ network cables. For more information about SFP+ network cables and SFP+ transceiver modules, see "Appendix C Ports and LEDs."

The following subsections describe several recommended IRF connection schemes, and all these schemes use a ring topology.

Connecting the IRF member switches in one rack

Use SFP+ network cables to connect the IRF member switches (9 switches in this example) in a rack as shown in Figure 44. The switches in the ring topology (see Figure 45) are in the same order as connected in the rack.

Figure 44 Connecting the switches in one rack

Figure 45 IRF fabric topology

Connecting the IRF member switches in a ToR solution

You can install IRF member switches in different racks side by side to deploy a top of rack (ToR) solution.

Figure 46 shows an example for connecting 9 top of rack IRF member switches by using SFP+ transceiver modules and optical fibers. The topology is the same as Figure 45.

Figure 46 ToR cabling

Configuring basic IRF settings

After you install the IRF member switches, power on the switches, and log in to each IRF member switch (see H3C S5150-EI 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.

· 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.

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

For more information about configuring basic IRF settings, see H3C S5150-EI Switch Series IRF Configuration Guide.

Connecting the physical IRF ports

Use twisted pair cables, SFP+ network cables, or SFP+ transceiver modules and fibers to connect the IRF member switches as planned.

Wear an ESD wrist strap when you connect SFP+ network cables or SFP+ transceiver modules and fibers. For how to connect them, see H3C SFP/SFP+/XFP Transceiver Modules and Network Cables Installation Guide.

Verifying the IRF fabric setup

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 H3C S5150-EI Switch Series Fundamentals Configuration Guide.)

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 Table 8.

Table 8 Displaying and maintaining IRF configuration and running status

Task	Command
Display information about the IRF fabric.	display irf
Display all members’ IRF configurations that take effect at a reboot.	display irf configuration
Display IRF fabric topology information.	display irf topology

NOTE:

To avoid IP address collision and network problems, configure a minimum of 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 H3C S5150-EI Switch Series IRF Configuration Guide.
