· 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.
· Ensure adequate ventilation for the switch and keep the protective vents of the switch unblocked.
· The switch can operate correctly only under correct voltage. Ensure that the input voltage is in the required voltage range labeled on the switch.
· To avoid electrical shocks, do not open the chassis while the switch is operating. As a best practice, do not open the chassis even if the switch is powered off.
· When installing the switch, always wear an ESD wrist strap. Make sure the wrist strap makes good skin contact and is reliably grounded.
Examining the installation environment
Before installing the switch, examine the installation environment. To ensure correct operation of your switch, make sure the installation environment meets the requirements listed in Table 1.
Table 1 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. |
|
Lightning protection |
Ground the switch correctly and verify the grounding. For more information, see "Connecting the grounding cable." · 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. |
|
Mechanical environment |
NOTE: 4M represents the mechanical environment condition defined by GB/T 4798.4. It has eight classes. The 4M4 class refers to places impacted by machines, running vehicles, ground blasting or piling. |
|
Dust and water resistance |
If you install the switch in an outdoor environment, make sure the installation and operating environments meet the requirements of IP55 rating protection. NOTE: IP indicates International Protection Rating. The first number "5" refers to the rating for preventing the solid particle from entering the cabinet. An outdoor cabinet cannot prevent dust intrusion perfectly, but the dust cannot damage the device. The second number "5" refers to the rating for preventing water from entering the cabinet. Water projected in jets against the enclosure from any direction cannot damage the device. |
|
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. |
|
Corrosive gas prevention |
The installation site must be free from corrosive gases such as acid gases and alkaline gases. |
|
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. |

· Data bits—8.
· Parity—None.
· Stop bits—1.
· Flow control—None.
Starting the switch
Pre-startup checklist
Before powering on the switch, verify that the following conditions are met:
· The power cord is correctly connected.
· The power source voltage is as required by the switch.
· The console cable is correctly connected.
· The configuration terminal (a PC, for example) has started, and the terminal parameters have been set correctly.
Powering on the switch
To power on the switch, connect the power cord to a power source and then turn on the circuit breaker.
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 vary by software version. For more information about Boot ROM menu options, see the software-matching release notes for the device.
After the startup completes, you can access the CLI to configure the switch. For more information about the configuration commands and CLI, see the configuration guides and command references for the switch series.
Setting up an IRF fabric
The Intelligent Resilient Framework (IRF) technology virtualizes multiple physical devices at the same layer into one virtual fabric for simplified topology, easy management, and improved network performance and availability.
The IE4520 switch series support IRF, allowing you to connect multiple switches physically into one logical fabric and set up a new intelligent network that features high availability, scalability, and easy management.
Only switches from the same switch series can set up an IRF fabric.

Planning for setting up an IRF fabric
Plan the following items for setting up an IRF fabric:
· IRF fabric size and member switch installation location
· IRF member roles and member IDs
· Candidate physical IRF ports
IRF fabric size and member switch installation location
The switching capacity of an IRF fabric equals the total switching capacities of all member switches. Determine the number and model of IRF member switches based on the network access demands and uplink requirements.
Determine the installation location for the member switches:
· 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: An IRF fabric is highly scalable. You can easily add new member devices to an IRF fabric after the fabric is set up. |
IRF member roles and member IDs
IRF uses two member roles: master and standby. When devices form an IRF fabric, they elect a master to manage and control the IRF fabric, and all the other devices back up the master. An IRF fabric has only one master switch. When the master device fails, the other devices automatically elect a new master.
Determine which switch you want to use as the master. You can affect the election result by assigning a high member priority to the intended master switch. For more information about the master election, see IRF Configuration Guide in the set of configuration guides for the switch series.
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.
IRF network topology
You connect the IRF member switches through IRF interfaces, the logical interfaces for the connections between IRF member switches. Each IRF member switch has two IRF interfaces: IRF-interface 1 and IRF-interface 2. To use an IRF interface, 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-interface 1 on one switch to the physical ports of IRF-interface 2 on the other switch.
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. As a best practice, use a ring topology to create an IRF fabric.
|
|
NOTE: · The front panel of the IE4520-30S-C switch is used as an example in the following two figures. · The IRF port connections in the two figures are for illustration only, and more connection methods are available. |
Figure 32 Daisy chain topology
Multiple types of ports on the switch can be used as IRF physical ports. For more information, see Table 4.
You can bind several IRF physical ports to an IRF interface for increased bandwidth and availability.
Candidate physical IRF ports
Reserve physical IRF ports on the member switches according to your topology and connection scheme.
Table 4 shows the physical ports that can be used for IRF connection and the port use restrictions.
Table 4 Candidate physical IRF ports and use restrictions
|
Chassis |
Candidate physical IRF ports |
Use restrictions |
|
IE4520-54S-C IE4520-54S-C-SEC |
All SFP+ ports on the front panel |
The SFP ports must operate at 10 Gbps. The IRF physical ports selected on the member switches must operate at the same rate. The ports on interface modules cannot be used as IRF physical ports. |
IRF connection scheme
You can use SFP+ transceiver modules and optical fibers or SFP+ cables for IRF connection. For the available transceiver module and optical fiber models, see hardware information and specifications for the switch series.
· For a short-distance IRF connection in an equipment room, use a SFP+ cable.
· For a long-distance IRF connection, use SFP+ transceiver modules and optical fibers.
The following subsections describe several H3C recommended IRF connection schemes by using SFP+ cables and SFP+ transceiver modules and optical fibers. As a best practice, use a ring topology to set up an IRF fabric. The following figures show examples of IRF connection schemes of four switches in a ring topology.
Connecting the IRF member switches in one rack
Connect the IRF member switches (4 switches in this example) in a rack as shown in Figure 34 if the switches are in one rack.
Figure 34 Connecting the switches in one rack
Figure 35 IRF fabric connection topology
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 Figure 36. Use SFP+ transceiver modules and optical fibers for connection if a large distance exists between the member switches.
Figure 36 ToR connection
Configuring basic IRF settings
After you install the IRF member switches, power on and log in to each member switch to configure basic IRF settings, including the IRF member ID, member priority (affecting the result of the master selection), and bindings between IRF interfaces and IRF physical ports.
For information about logging in to the switch, see login management configuration in Fundamentals Configuration Guide in the set of configuration guides for the switch series.
For information about configuring basic IRF settings, see IRF Configuration Guide in the set of configuration guides for the switch series.
Connecting the IRF member switches

|
CAUTION: Wear an ESD wrist strap when you connect the IRF physical ports. Make sure the strap makes good skin contact and is reliably grounded. |
Connect the IRF member switches based on the network topology and cabling scheme. For information about connecting the transceiver modules and cables, 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 on 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 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 Table 5.
Table 5 Displaying and maintaining IRF configuration and running status

NOTE: An IRF link failure causes an IRF fabric to split in two IRF fabrics operating with the same Layer 3 settings, including the same IP address. To avoid IP address collision and network issues, IRF uses multi-active detection (MAD) mechanisms to detect the presence of multiple identical IRF fabrics, handle collisions, and recover from faults. For more information about MAD, see IRF Configuration Guide in the set of configuration guides for the switch series. |
