1 Preparing for installation
The H3C S9820-64H switch is a high-density intelligent 100G switch developed for data center and high-end campus networks, providing powerful hardware forwarding capacity and abundant data center features.
The switch provides the following ports and FRUs:
· 100G QSFP28 ports.
· Two 1G management Ethernet ports (one fiber port and one copper port).
· Removable fan trays in redundancy mode and flexible airflows. By using different fan trays, you can change the airflow direction of the chassis to adapt to ventilation needs.
· Removable power supplies in redundancy mode.
Safety recommendations
To avoid any equipment damage or bodily injury caused by incorrect 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.
· 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.
· To avoid ESD damage, always wear an ESD wrist strap when replacing power supplies and fan trays.
Examining the installation site
The switch must be used indoors. Make sure the installation site meets the following requirements:
· Adequate clearance is reserved at the air inlet and outlet vents for ventilation.
· The rack 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 devices from entering the top device.
· The rack is sturdy enough to support the switch and its accessories.
· The rack 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 appropriate temperature and humidity in the equipment room in the acceptable range. For more information, see H3C S9820-64H Switch Hardware Information and 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 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.
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 switch requirement for cleanliness.

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.

Grounding the switch
|
|
CAUTION: · Correctly connecting the grounding cable is crucial to lightning protection and EMI protection. · To guarantee the grounding effect, connect the switch to a grounding strip in the equipment room by using the grounding cable provided with the switch. |
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 a switch by using a grounding strip at the installation site.
|
|
NOTE: The grounding terminals in this section are for illustration only. |
|
|
WARNING! Connect the grounding cable to the grounding system in the equipment room. Do not connect it to a fire main or lightning rod. |
To ground the switch by using a grounding strip:
1. Attach the single-hole grounding lug or two-hole grounding lug of the grounding cable to a grounding point on the chassis. For more information, see "Connecting the grounding cable to the chassis."
2. Remove the hex nut of a grounding post on the grounding strip.

4 Setting up an IRF fabric
You can use H3C IRF technology to connect and virtualize multiple S9820-64H switches into a large virtual switch called an "IRF fabric" for flattened network topology, and high availability, scalability, and manageability.

5. Configure basic IRF settings. |
See H3C S9820-64H Switch Virtual Technologies Configuration Guide. |
|
6. Connect the physical IRF ports. |
Connect the physical IRF ports on switches. Use QSFP28 transceiver modules and fibers for connections over long distances. Use QSFP28 cables for connections over short distances. 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
Determine 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.
As your business grows, you can add member switches into the 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 H3C S9820-64H Switch Virtual Technologies 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 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 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 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
You can use a QSFP28 transceiver module and fiber or a QSFP28 cable to connect QSFP28 ports on the S9820-64H switches to set up a 100-GE IRF physical connection.
You can bind several ports to an IRF port for increased bandwidth and availability.
Identifying physical IRF ports on the member switches
Identify the QSFP28 ports for IRF connections on the member switches according to your topology and connection scheme.
All the QSFP28 ports on the switch can be used for IRF connections. However, the 25G ports and 10G ports split from a QSFP28 port do not support IRF connections. The QSFP28 ports connected by a QSFP+ transceiver module and fiber or a QSFP+ cable do not support IRF connections.
Planning the cabling scheme
You can use QSFP28 cables or QSFP28 transceiver modules and fibers to connect the S9820-64H switches for IRF connections.
If the switches are all in one equipment room, choose QSFP28 cables for IRF connections. If the switches are far away from one another, choose QSFP28 transceiver modules and fibers for IRF connections.
For more information about available cables, see H3C S9820-64H Switch Hardware Information and Specifications.
The following subsections describe several IRF connection schemes by using the QSFP28 cables and QSFP28 transceiver modules and fibers. As a best practice, use the ring topology for IRF connections.
Connecting the IRF member switches in one rack
Figure4-4 shows an example for connecting four IRF member switches in a rack. 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
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 four top of rack IRF member switches. The topology is the same as Figure4-5.
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 S9820-64H Switch 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.
· Execute the display irf configuration command to verify the basic IRF settings.
For more information about configuring basic IRF settings, see H3C S9820-64H Switch Virtual Technologies Configuration Guide.

|
CAUTION: Wear an ESD wrist strap when you install cables and transceiver modules and fibers. For more information, see the installation guide for the transceiver modules and cables. |
Use transceiver modules and fibers or cables to 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 or SNMP to access the IRF fabric from the network management station. (See H3C S9820-64H Switch 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 Table4-1.
