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 Table1-2.
Table1-2 Checking list for the installation environment
|
Item |
Requirements |
|
Ventilation and heat dissipation |
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 |
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 S5120V3-EI & S5120V3-LI & S5120V3-SI Switch Series Hardware Information and Specifications. |
|
Lightning protection |
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 |
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. Table1-3 describes the switch requirement for cleanliness.

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.

This installation method is applicable to the S5120V3-30MS-UPWR-DP-EI switch.
Attaching the front mounting brackets and shoulder screws to the switch
The switch provides two installation positions on its side for the front mounting brackets. One is near the power supply side and the other is near the port side. The following procedure describes how to attach the front mounting brackets to the installation position near the port side. The power supply-side mounting is similar.
To attach the front mounting brackets and shoulder screws to the switch:
1. Place the wide flange of the front mounting bracket against the chassis side panel. Align the mounting bracket installation holes with the screw holes in the chassis. See Figure2-16.
2. Use M4 screws to attach the mounting bracket to the chassis, and then fasten the M4 screws. As a best practice, use a torque of 12 kgf-cm (1.18 Nm) to fasten the M4 screws.
3. Repeat the preceding two steps to attach the other mounting bracket to the chassis.
4. Unpack the shoulder screws and attach them to the chassis. As a best practice, use a torque of 12 kgf-cm (1.18 Nm) to fasten the shoulder screws.
Two installation positions as red-marked in Figure2-16 are available for shoulder screws. Select one as required.
Figure2-16 Attaching the front mounting brackets and shoulder screws to the chassis (port-side mounting position for mounting brackets)
Attaching the rear mounting brackets to the rack
1. Determine the switch installation position in the rack.
2. Orient the rear mounting brackets with the wide flange inside or outside the rack as required.
3. Use M6 screws and cages nuts (user-supplied) to attach the rear mounting brackets to the rear rack posts. As a best practice, use a torque of 30 kgf-cm (2.94 Nm) to fasten the M6 screws.
Do not fully tighten the M6 screws before mounting the switch in the rack.

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 IRF fabric setup scheme based on the user network and device conditions: · 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", "Mounting the switch on a workbench", or "Mounting the switch on a wall." |
|
3. Connect grounding cables 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 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. 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 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. See Table4-2 for the available IRF physical ports. 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 S5120V3-28S-EI switches. The IRF port connections in the two figures are for illustration only, and more connection methods are available.

· All physical ports to be bound to an IRF logical interface must have the same data rate. · An SFP+ port can be used as an IRF physical port only when it operates at 10 Gbps. · A 10/100/1000BASE-T autosensing Ethernet port, 1000/100BASE-T autosensing Ethernet port, or SFP port can be used as an IRF physical port only when it operates at 1 Gbps. · A 2.5G/1000/100BASE-T autosensing Ethernet port can be used as an IRF physical port only when it operates at 2.5 Gbps. · For a switch that has six SFP+ ports, use the four SFP+ ports with the highest numbers as IRF ports. For a switch that has four SFP+ ports, use the two SFP+ ports with the highest numbers as IRF ports. Using these ports as IRF ports can prevent issues such as IRF split, because IRF protocol packets from these ports can be forwarded in a queue with a higher priority. |

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.
· 1000/100BASE-T autosensing Ethernet port and 2.5G/1000/100BASE-T autosensing Ethernet port—Category 5e or above twisted-pair cable.
· SFP port—GE SFP fiber transceiver modules and optical fibers or GE SFP cables. For the available models, see ports in S5120V3-EI & S5120V3-LI & S5120V3-SI Switch Series Hardware Information and Specifications.
· SFP+ port—SFP+ fiber transceiver module and optical fiber or SFP+ cable. For the available transceiver models and cables, see ports in S5120V3-EI & S5120V3-LI & S5120V3-SI Switch Series Hardware Information and Specifications.
If the IRF member switches are far away from one another, use SFP/SFP+ 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.
|
|
IMPORTANT: In these schemes, all physical IRF ports are located on the same side. If physical IRF ports are on different sides, you must calculate or measure the required cable length. |
Connecting the IRF member switches in one rack
Connect the IRF member switches (four 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 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
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 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 Table4-3.

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. |
5 Maintenance and troubleshooting
