Examining the installation environment

To ensure correct operation of your switch, make sure the installation environment meets the requirements listed in Table1-2.
Table1-2 Checking list for the installation environment:

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 technical specifications in the hardware information and specifications for the switch .

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.

·           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 removable components, always wear an ESD wrist strap when you install or remove the device or removable 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 limits.”

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.

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.

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.

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.

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.

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 IRF Configuration Guide for the switch.

Maintenance and troubleshooting

Power supply failure
The switch uses removable power supplies. You can determine whether a power supply is faulty by observing the status LED on the power supply.

• Symptom
  The status LED on the power supply is not steady green, which indicates that the power supply is faulty.

• Solution
  To resolve the issue:

1. Verify that the power supply model is as required by the switch.
2. Verify that the power supply is securely installed in the switch.
3. Verify that the operating temperature of the switch is in an acceptable range and the power supply has good ventilation.
4. If the issue persists, contact Intelbras Support.  

To replace a power supply, see “Installing and removing power supplies.”

Fan tray failure

CAUTION: If more than one fan tray fails during the switch operation, do not remove the failed fan trays simultaneously. Replace the fan trays one by one and finish replacing each fan tray within 3 minutes.
