To connect the switch to the configuration terminal through a USB-to-RJ45 console cable:
Setting terminal parameters
To configure and manage the switch through the console port, you must run a terminal emulator program, such as TeraTermPro, on your configuration terminal. 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. Configure the terminal parameters as follows: · Bits per second–9,600. · Data bits–8. · Parity–None. · Stop bits–1. · Flow control–None.
Starting the switch
Pre-start checklist
Before powering on the switch, verify the following items: · The power cord is correctly connected. · The input power voltage is as required by the switch. · The console cable is correctly connected. · The PC has started, and the terminal parameters have been correctly configured.
Powering 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 process is completed, you can access the CLI to configure the switch. For more information about the configuration commands, see the configuration guides and command references for the switch.

4 Setting up an IRF fabric (Stacking)
You can use Intelbras IRF technology to connect and virtualize multiple SC 5530 switches into a large virtual switch called an “IRF fabric” for flattened network topology, and high availability, scalability, and manageability.
A SC 5530 switch can form an IRF fabric only with switches in the same series
All IRF member devices must run the same software image version. Make sure the software auto-update feature is enabled on all member devices.

See “Installing the switch in a 19-inch rack.”
See “Grounding the switch” and “Connecting the power cord.”
N/A
See IRF Configuration Guide for the switch series.
Connect IRF member switches. Use QSFP+/QSFP28 transceiver modules and optical fibers for long distance connection. Use QSFP+/QSFP28 copper cables for short distance connection. 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 configuration guides and command references for the switch. 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.

4-2

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 QSFP28 ports on the switch can provide 40GE/100GE IRF connection. 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. The IRF port connections in the two figures are for illustration only, and more connection methods are available.

Reserving physical IRF ports on the member switches
Reserve the physical IRF ports on the member switches according to your topology and connection scheme. QSFP28 ports on the switch can be used for IRF connection. 25-GE/10-GE breakout interfaces split from a QSFP28 port cannot be used for IRF connection.
IMPORTANT: · All physical ports to be bound to an IRF logical interface must have the same data rate. · QSFP28 ports on the switch operate at 40 Gbps by default. Licenses are available for you to
increase the QSFP28 port speed to 100 Gbps.
Planning the cabling scheme
You can use QSFP+/QSFP28 transceiver modules and optical fibers or QSFP+/QSFP28 copper cables for IRF connection: · For a short-distance IRF connection in an equipment room, use a QSFP+/QSFP28 cable. · For a long- distance IRF connection, use QSFP+/QSFP28 transceiver modules and optical
fibers. The following subsections describe several Intelbras recommended IRF connection schemes. All these schemes use a ring topology. The ring topology is not applicable to IRF setup with two devices.
4-4

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 (4 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 (4 switches in this example) in different racks side by side to deploy a top of rack (ToR) solution as shown in Figure4-6. Use QSFP+/QSFP28 transceiver modules and optical fibers for connection if a large distance exists between the member switches.

Configuring basic IRF settings

After you install the IRF member switches, power on the switches, and log in to each IRF member switch to configure their member IDs, member priorities, and IRF port bindings. For information about accessing the switch, see Fundamentals Configuration Guide for the switch. For more information about configuring basic IRF settings, see IRF Configuration Guide for the switch.
Connecting the physical IRF ports

Connect the IRF member switches as planned. Wear an ESD wrist strap when you connect cables or transceiver modules and fibers. For information about how to connect them, see Intelbras 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 Fundamentals Configuration Guide for the switch.)
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.
