· 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 power input voltage is as required by the power supply.
· To avoid electrical shocks, do not open the chassis while the switch is operating or when the switch is just powered off.
· During switch installation, wear an ESD wrist strap. Make sure the strap makes good skin contact and is reliably grounded.
Examining the installation site
The switch must be used indoors. You can mount your switch in a rack or on a workbench. Make sure the following requirements are met:
· 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 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 different switch models, 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.

For more information about the configuration commands and CLI, see H3C S6520X-SI Switch Series Configuration Guides and H3C S6520X-SI Switch Series Command References.
4 Setting up an IRF fabric
You can use H3C IRF technology to connect and virtualize S6520X-SI switches into a large virtual switch called an "IRF fabric" for flattened network topology, and high availability, scalability, and manageability.
An S6520X-SI switch can set up an IRF fabric only with switches from the same switch series.
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 |
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 S6520X-SI Switch Series IRF Configuration Guide or H3C S6520X-SI 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 switch, 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 S6520X-SI Switch Series IRF Configuration Guide or H3C S6520X-SI 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.
Multiple types of ports (see Table4-1 for the port types) on the S6520X-SI switches can be used for IRF connections. 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 S6520X-26C-SI 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.

Planning the cabling scheme
Use the following cables to connect the IRF physical ports on the switch:
· 5G/2.5G/1000BASE-T autosensing Ethernet port—Category 5e or above twisted pair cable.
· 5G/2.5G/1000/100BASE-T autosensing Ethernet port—Category 5e or above twisted pair cable.

· 1/10GBASE-T autosensing Ethernet port—Category 6 or above twisted pair cable.
· SFP+ port—SFP+ transceiver module and optical fiber or SFP+ cable. For the available transceiver module and cable types, see ports in Hardware Information and Specifications.
· SFP28 port—SFP28 transceiver module and optical fiber or SFP28 cable. For the available transceiver module and cable types, see ports in Hardware Information and Specifications.
· QSFP+ port—QSFP+ transceiver modules and optical fiber or QSFP+ cable. For the available transceiver module and cable types, 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 by using SFP+ cables and SFP+ transceiver modules and fibers. 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
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
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.
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 S6520X-SI 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 module to an IRF port, you must install the interface module first.
· Execute the display irf configuration command to verify the basic IRF settings.
For more information about configuring basic IRF settings, see H3C S6520X-SI Switch Series IRF Configuration Guide or H3C S6520X-SI Switch Series Virtual Technologies Configuration Guide, depending on the software version.
Connecting the physical IRF ports
Use twisted pair cables, cables, or transceiver modules and fibers to connect the IRF member switches as planned.
Wear an ESD wrist strap when you connect cables or transceiver modules and fibers. For how to connect them, 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 S6520X-SI 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.
