Safety recommendations

To avoid equipment damage or bodily injury, 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 at the installation site and keep the air inlet and outlet vents of the switch free of obstruction.

· Make sure the operating voltage is as required.

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

· Always wear an ESD wrist strap when installing the switch. Make sure the strap makes good skin contact and is reliably grounded.

Examining the installation environment

To ensure correct operation of your switch, make sure the installation environment meets the requirements listed in Table 2.

Table 2 Checking list for the installation environment

Item	Requirements
Ventilation and heat dissipation	CAUTION: To ensure correct operation of your device, make sure the installation environment is adequately ventilated to prevent the switch from overheating. · Ensure a minimum clearance of 10 cm (3.94 in) around the chassis. · Do not install the device near a heat source, for example, a stove or heater. · Ensure air ventilation in the installation environment. · Do not block the ventilation holes in the device or power adapter.
Anti-moisture	CAUTION: Water or moisture might damage the circuits of the device. · Do not place the device near water or in a damp environment. · Install the switch in a clean, dry, and ventilated place where temperature is controlled in a stable range. · Make sure the installation environment is free from water leakage or condensation. If required, install a dehumidification device (such as an air conditioner with a dehumidification function or a dedicated dehumidifier). · Do not operate the device under or near the water source, such as the wash basin, laundry room, or areas with high humidity. · Do not touch the device with wet hands.
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 issues 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 hardware information and specifications for the switch series
Lightning protection	CAUTION: Ground the switch correctly and verify the grounding. For more information, see "Grounding the switch." · If you ground the switch by using a grounding strip, make sure the grounding resistance of the grounding strip in the equipment room is less than 1W. · If you ground the switch by using a grounding conductor buried in the earth ground, make sure the grounding resistance of the grounding conductor in the ground is less than 10W. · Route the signal cables along indoor walls, bury the cables in the earth ground, or thread the cables through steel tubes. Install a signal lightning arrester with a nominal discharge current for a corresponding network interface. · Keep the signal cables far from power cords and lightning rod down conductors. · As a best practice, route power cords indoors. If an AC power cord is routed from outdoors, connect the AC power cord first to a power lightning arrester before leading it to the AC power port on the switch. Make sure the power lightning arrester has a nominal discharge current and the total length of the power cord from the power lighting arrester to the power port on the switch is less than 5 m (16.40 ft). · Ground the switch, rack, independent power supplies, and lightning arresters separately. · You must ground optical fibers with reinforcing metal stiffener from outdoors on an optical distribution frame (ODF) or fiber splice enclosure.
Cable routing	CAUTION: Do not run an Ethernet cable and power cord in parallel. · Route different types of cables separately. · Keep power cords a minimum of 5 cm (1.97 in) away from other cables.
ESD prevention	· Ground the switch correctly. · To avoid ESD damage to the device or components, always wear an ESD wrist strap when you install or remove the device or components. · Make sure the wrist strap has good skin contact and is reliably grounded.
Cleanliness	· For more information, see "Cleanliness."
Corrosive gas prevention	The installation site must be free from corrosive gases such as acid gases and alkaline gases. For more information, see "Corrosive gas limit."
EMI	· 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 device far away from radio transmitting stations, radar stations, and high-frequency devices. · Use electromagnetic shielding, for example, shielded interface cables, when necessary.

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. Table 3 describes the switch requirement for cleanliness.

Table 3 Switch requirement for cleanliness

Substance	Particle diameter	Concentration limit
Dust particles	≥ 0.5 µm	≤ 1.8 × 10⁷ particles/m³

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 do not exceed the concentration limits as shown in Table 4.

Table 4 Corrosive gas concentration limits

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.

Grounding the switch

WARNING!

Correctly connecting the switch grounding cable is crucial to lightning protection, ESD, and EMI protection. For information about lightning protection, see H3C Network Devices Lightning Protection Guide.

To protect against the following types of problems, use a grounding cable to connect the device to the earthing facility at the installation site:

· Bodily injury from electric shocks.

· Device and power and data line damages.

· Electrical fires, lightning strokes, electromagnetic coupling interferences, ESD damages.

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

· Grounding the switch by using the PE wire of the AC power cord

NOTE:

The chassis views and power supply and grounding terminal positions in the following figures are for illustration only.

Grounding the switch with a grounding strip

WARNING!

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

If the installation site does not have grounding strips, but earth ground is available, hammer a 2.5 m (8.20 ft) or longer angle iron or steel tube into the earth ground to act as a grounding conductor. Make sure a minimum of 0.7 m (2.30 ft) is left between the top of the grounding conductor and the ground. In cold areas, bury the grounding conductor below the frozen soil layer. In areas with thin soil or rocky gravel, determine the depth for burying the grounding conductor based on the actual condition.

If zinc-coated steel is used, the following dimensions requirements must be met:

· Angle iron—A minimum of 50 × 50 × 5 mm (1.97 × 1.97 × 0.20 in).

· Steel tube—A minimum of 3.5 mm (0.14 in) in thickness.

· Flat steel—A minimum of 40 × 4 mm (1.57 × 0.16 in).

· Round steel—A minimum of 10 mm (0.39 in).

Weld the yellow-green grounding cable to the angel iron or steel tube and treat the joint for corrosion protection.

Grounding the switch by using the PE wire of the AC power cord

If the installation site has no grounding strips or earth ground, ground an AC-powered switch through the PE wire of the power cord. Make sure the following requirements are met:

· The power cord has a PE wire.

· 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. If the ground contact in the power outlet is not connected to the ground, report the problem and reconstruct the grounding system.

NOTE:

To guarantee the grounding effect, use the grounding cable provided with the switch to connect to the grounding strip in the equipment room.

Verifying the connection after grounding the switch

· If you ground the switch with a grounding strip:

a. Use a multimeter to measure the resistance between the switch grounding terminal and grounding point, and make sure the resistance is less than 0.1W.

b. Use a grounding resistance tester to measure the grounding resistance of the grounding strip, and make sure the grounding resistance is less than 1W.

· If you ground the switch with a grounding conductor buried in the earth ground:

a. Use a multimeter to measure the resistance between the switch grounding terminal and grounding point, and make sure the resistance is less than 0.1W.

b. Use a grounding resistance tester to measure the grounding resistance of the angle iron in the ground, and make sure the grounding resistance is less than 10W. For locations with high soil resistivity, sprinkle some resistance reducer to reduce soil resistivity or replace soil around the grounding strip with soil with lower resistance.

For information about resistance measurement, see H3C Network Devices Lightning Protection Guide.

Setting up an IRF fabric

IMPORTANT:

The LS-5008PV5-EI and LS-5008PV5-EI-HPWR switches do not support IRF, so this section is not applicable to the LS-5008PV5-EI and LS-5008PV5-EI-HPWR switches.

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

For the S5500V3-EI switch series and S3100V3-SI switch series, you can only use the switches in the same group to set up an IRF fabric. For the other switch series, you can set up an IRF fabric with switches from the same switch series.

IRF fabric setup flowchart

Figure 37 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 IRF physical 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 grounding cables and power cords.	See "Grounding the switch," "Installing and removing a power supply," and "Connecting the power cord."
4. Power on the switches.	N/A
5. Configure basic IRF settings.	See the IRF configuration guide or virtual technologies configuration guide for the switch series, depending on the software version.
6. Connect the IRF physical ports.	Connect IRF physical ports on switches. For long-distance connection, use SFP/SFP+ transceiver modules and optical fibers. For short-distance connection, use twisted-pair cables or SFP/SFP+ cables. 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.

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 the IRF configuration guide or virtual technologies configuration guide for the switch series, 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 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 switch can form an IRF fabric only with switches from the same switch series. For the physical ports that can be used for IRF connections on each switch model and the restrictions for using the ports, see Table 15. The IRF physical ports can set up IRF connections only when operating at their highest speeds. For example, a 10-GE port must operate at 10 Gbps. A 1-GE port must operate at 1 Gbps.

You can bind multiple ports to an IRF port for increased bandwidth and availability.

NOTE:

The following figures use the SFP+ ports on S5120V2-28P-HPWR-LI switches as an example. For the ports that can be used for IRF connections, see Table 15.

Identifying IRF physical ports on the member switches

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

To uses physical ports on a switch in the S5500V3-SI switch series (excluding the S5500V3-24P-SI and S5500V3-48P-SI) for IRF connection, obey the following rules as a best practice:

· Use four highest numbered SFP+ ports if the switch has six SFP+ ports.

· Use two highest numbered SFP+ ports if the switch has four SFP+ ports.

With these ports as IRF physical ports, the IRF packets are placed in queues of higher forwarding priorities, ensuring smooth IRF packet forwarding in the event of large amounts of data packets and avoiding IRF splitting and other faults.

Table 15 shows the physical ports that can be used for IRF connection and the port use restrictions.

Planning the cabling scheme

Use the following cables to connect the IRF physical ports on the switches:

· 10/100/1000BASE-T autosensing Ethernet port—Category 5 or above twisted-pair cables.

· SFP port—GE SFP fiber transceiver modules and optical fibers, GE SFP copper transceiver modules and twisted-pair cables, or GE SFP cables. For the available models, see ports in hardware information and specifications for the switch series.

· SFP+ port—SFP+ transceiver modules and optical fibers or SFP+ cables. For the available models, see ports in hardware information and specifications for the switch series.

If the IRF member switches are far away from one another, use transceiver modules and optical fibers. If the IRF member switches are all in one equipment room, use twisted pair cables or SFP/SFP+ cables.

The following subsections describe several H3C recommended IRF connection schemes by using SFP cables and SFP transceiver modules and fibers. All these schemes use a ring topology.

Connecting the IRF member switches in one rack

Connect the IRF member switches (4 switches in this example) in a rack as shown in Figure 40. The switches in the ring topology (see Figure 41) are in the same order as connected in the rack.

Figure 40 Connecting the switches in one rack

Figure 41 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 42 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 the fundamentals configuration guide for the switch series) 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.

· 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 or virtual technologies configuration guide for the switch series, depending on the software version.

Connecting the IRF physical ports

Prepare and connects cable based on the network topology and connection methods as planned.

Wear an ESD wrist strap when you install transceiver modules and fibers. For the installation method 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 or SNMP to access the IRF fabric from the network management station. (See the fundamentals configuration guide for the switch series.)

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 16.

Table 16 Displaying and maintaining IRF configuration and running status

Task	Command
Display IRF fabric information.	display irf
Display basic IRF settings for each member device.	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 the IRF configuration guide or virtual technologies configuration guide for the switch series, depending on the software version.
