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 powering on the switch.

· Make sure the operating voltage is as required by the power modules.

· To avoid electrical shocks, do not open the chassis while the switch is operating or when the switch is just powered off.

· When replacing field replaceable units (FRUs), including expansion cards, power modules, and fan trays, 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.

· 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

For correct operation and long service life of your switch, maintain the temperature and humidity in the equipment room at acceptable ranges.

· 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 cause problems including loose mounting 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 the switch, see technical specifications in Hardware Information and Specifications.

Cleanliness

Dust buildup on the chassis might cause electrostatic adsorption and dust corrosion, resulting in poor contact of metal connectors and contact points. This might shorten the device's lifetime and even cause device failure in the worst case. Table1-1 describes the dust concentration limits in the equipment room.

Table1-1 Dust concentration limits in the equipment room

Substance	Particle diameter	Concentration limit
Dust particles	≥ 0.5 µm	≤ 3.5 × 10⁶ particles/m³
Dust particles	≥ 5 µm	≤ 3 × 10⁴ particles/m³
Dust (suspension)	≤ 75 µm	≤ 0.2 mg/m³
Dust (sedimentation)	75 µm to 150 µm	≤ 1.5 mg/(m²h)

To maintain cleanliness in the equipment room, follow these guidelines:

· Keep the equipment room away from pollution sources. Do not smoke, eat, or drink in the equipment room.

· Use double-layer glass in windows and seal doors and windows with dust-proof rubber strips. Use screen doors and window screens for doors and windows open to the outside and make sure the external windows are air tight.

· Use dustproof materials for floors, walls, and ceilings and use wallpaper or matt paint that does not produce powders.

· Clean the equipment room regularly and clean the air filters of the rack each month.

· Wear ESD clothing and shoe covers before entering the equipment room, keep the ESD clothing and shoe covers clean, and change them frequently.

Corrosive gas limit

Corrosive gases can accelerate corrosion and aging of metal components. Make sure the corrosive gases in the equipment room do not exceed the concentration limits as shown in Table1-2.

Table1-2 Corrosive gas concentration limits in the equipment room

Gas	Average concentration (mg/m³)	Maximum concentration (mg/m³)
SO2	0.3	1.0
H2S	0.1	0.5
Cl2	0.1	0.3
HCI	0.1	0.5
HF	0.01	0.03
NH3	1.0	3.0
O3	0.05	0.1
NOX	0.5	1.0

CAUTION:

As a best practice, control the corrosive gas concentrations in the equipment room at their average values. Make sure the corrosive gas concentrations do not exceed 30 minutes per day at their maximum values.

To control corrosive gases, use the following guidelines:

· As a best practice, do not build the equipment room in a place with a high concentration of corrosive gases.

· Make sure the equipment room is not connected to sewer, vertical shaft, or septic tank pipelines and keep it far away from these pipelines. The air inlet of the equipment room must be away from such pollution sources.

· Use environmentally friendly materials to decorate the equipment room. Avoid using organic materials that contains harmful gases, such as sulfur or chlorine-containing insulation cottons, rubber mats, sound-proof cottons, and avoid using plasterboards with high sulfur concentration.

· Place fuel (diesel or gasoline) engines separately. Do not place them in the same equipment room with the device. Make sure the exhausted air of the engines will not flow into the equipment room or towards the air inlet of the air conditioners.

· Place batteries separately. Do not place them in the same room with the device.

· Employ a professional company to monitor and control corrosive gases in the equipment room regularly.

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, use the following guidelines:

· 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.

· To prevent signal ports from getting damaged by overvoltage or overcurrent caused by lightning strikes, route interface cables only indoors.

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

· Flat-blade screwdriver

· Phillips screwdriver

· ESD wrist strap

All these installation tools are user supplied.

Grounding the switch

WARNING!

Correctly connecting the 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 to minimize the potential for system damage, maximize the safety at the site, and minimize EMI susceptibility of the system.

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 strip in the equipment room. Do not connect it to a fire main or lightning rod.

· To guarantee the grounding effect and avoid switch damage, use the grounding cable provided with the switch to connect the switch to a grounding strip in the equipment room.

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. Fasten the screw.

4 Setting up an IRF fabric

You can use H3C IRF technology to connect and virtualize S5560X-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

Figure4-1 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 S5560X-EI Switch Series IRF Configuration Guide or H3C S5560X-EI Switch Series Virtual Technologies Configuration Guide, depending on the software version.
6. Connect the physical IRF ports	Connect physical IRF ports on switches. 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 S5560X-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 S5560X-EI Switch Series IRF Configuration Guide or H3C S5560X-EI Switch Series Virtual Technologies Configuration Guide, depending on the software version.

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 S5560X-EI switches provide 5-GE/10-GE/25-GE/40-GE IRF connections through multiple types of ports (see Table4-1 for the port types). You can bind several IRF physical ports to an IRF port for increased bandwidth and availability.

Figure4-2 and Figure4-3 show the topologies of an IRF fabric made up of three S5560X-30C-EI switches. The IRF port connections in the two figures are for illustration only, and more connection methods are available.

Figure4-2 IRF fabric in daisy chain topology

Figure4-3 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.

Table4-1 shows the physical ports that can be used for IRF connection and the port use restrictions.

Table4-1 Physical IRF port requirements

Chassis	Candidate physical IRF ports	Requirements
S5560X-34S-EI S5560X-54S-EI	· Four SFP+ ports on the front panel · Two QSFP+ ports on the rear panel	· All physical ports to be bound to an IRF port must have the same data rate. · Physical ports on interface cards and the front panel can be bound to the same IRF port. · If a QSFP+ port is split into four virtual SFP+ ports, the QSFP+ port cannot be used as a physical IRF port.
S5560X-30C-EI S5560X-30C-PWR-EI S5560X-54C-EI S5560X-54C-PWR-EI S5560X-30F-EI S5560X-54F-EI	· Four fixed SFP+ ports on the front panel · Ports on the interface cards on the rear panel: ¡ 1/10GBASE-T autosensing Ethernet ports ¡ 5G/2.5G/1000BASE-T autosensing Ethernet ports ¡ 10G/5G/2.5G/1000BASE-T autosensing Ethernet ports ¡ SFP+ ports ¡ SFP28 ports ¡ QSFP+ ports
S5560X-30F-EIF	All SFP+ ports and QSFP+ ports on the front panel

Planning the cabling scheme

The cables available for connecting two peer IRF physical ports vary by port type:

· 1/10GBASE-T, 5G/2.5G/1000BASE-T, and 10G/5G/2.5G/1000BASE-T autosensing Ethernet ports—For the available cables, see ports in Hardware Information and Specifications.

· SFP+ ports—SFP+ transceiver modules and optical fibers or SFP+ cables. For the available transceiver modules and cables, see ports in Hardware Information and Specifications.

· SFP28 ports—SFP28 transceiver modules and optical fibers or SFP28 cables. For the available transceiver modules and cables, see ports in Hardware Information and Specifications.

· QSFP+ ports—QSFP+ transceiver modules and optical fibers or QSFP+ cables. For the available transceiver modules and cables, see ports in Hardware Information and Specifications.

For a short-distance IRF connection in an equipment room, use a twisted-pair cable, SFP+ cable, SFP28 cable, or QSFP+ cable.

For a long-distance IRF connection, use SFP+/SFP28/QSFP+ transceiver modules and optical fibers.

The following subsections describe several H3C recommended IRF connection schemes. All these schemes use a ring topology.

IMPORTANT:

In these schemes, all physical IRF ports are located on the same side. If physical IRF ports are on different sides, you must measure the distance between them to select an appropriate cable.

Connecting the IRF member switches in one rack

Use twisted pair/SFP+/SFP28/QSFP+ cables to connect the IRF member switches (9 switches in this example) in a rack as shown in Figure4-4. The switches in the ring topology (see Figure4-5) are in the same order as connected in the rack.

Figure4-4 Connecting the switches in one rack

Figure4-5 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.

Figure4-6 shows an example for connecting 9 top of rack IRF member switches by using SFP+/ SFP28/QSFP+ transceiver modules and optical fibers. The topology is the same as Figure4-5.

Figure4-6 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 S5560X-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.

· 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 H3C S5560X-EI 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 H3C S5560X-EI Switch Series IRF Configuration Guide or H3C S5560X-EI Switch Series Virtual Technologies Configuration Guide, depending on the software version.

Connecting the physical IRF ports

Use twisted pair/SFP+/SFP28/QSFP+ cables, or SFP+/SFP28/QSFP+ transceiver modules and fibers to connect the IRF member switches as planned.

Wear an ESD wrist strap when you connect twisted pair/SFP+/SFP28/QSFP+ cables or SFP+/SFP28/QSFP+ transceiver modules and fibers. For the connection methods and precautions, see H3C 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 S5560X-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 Table4-2.

Table4-2 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 S5560X-EI Switch Series IRF Configuration Guide or H3C S5560X-EI Switch Series Virtual Technologies Configuration Guide, depending on the software version.

5 Maintenance and troubleshooting
