Safety recommendations

To avoid any equipment damage or bodily injury caused by improper use, 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 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 power-on.
 Make sure the operating voltage is in the required range.
 To avoid electrical shocks, do not open the chassis while the switch is operating.
 To avoid damage caused by improper operation, do not open the chassis even if the switch is

powered off.

 When replacing power modules, wear an ESD wrist strap to avoid damaging the units.

Examining the installation site

The switch must be used indoors. You can mount your switch in a rack or on a workbench, but make
sure:

 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 as described in "Appendix A Chassis

views and technical specifications."

 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 bring problems

including loose captive 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."

Cleanliness

Dust buildup on the chassis might result in electrostatic adsorption, which causes poor contact of
metal components and contact points, especially when indoor relative humidity is low. In the worst
case, electrostatic adsorption can cause communication failure.

EMI

Table 2 Dust concentration limit in the equipment room

The equipment room must also meet strict limits on salts, acids, and sulfides to eliminate corrosion
and premature aging of components, as shown in Table 3.

Table 3 Harmful gas limits in the equipment room

All electromagnetic interference (EMI) sources, from outside or inside of the switch and application
system, adversely affect the switch in the following ways:

 A conduction pattern of capacitance coupling.
 Inductance coupling.
 Electromagnetic wave radiation.
 Common impedance (including the grounding system) coupling.

Grounding the switch

The power input end of the switch has a noise filter, whose central ground is directly connected to the
chassis to form the chassis ground (commonly known as PGND). You must securely connect this
chassis ground to the earth so the faradism and leakage electricity can be safely released to the
earth to minimize EMI susceptibility of the switch.

You can ground the switch in one of the following ways, depending on the grounding conditions
available at the installation site:

 Grounding the switch with a grounding strip
 Grounding the switch with a grounding conductor buried in the earth ground
 Grounding the switch by using the AC power cord

Concurrent login users

The Web interface allows a maximum of 32 concurrent users. If this limit is reached, login attempts
will fail.

Logging in to the Web interface for the first time

By default, HTTP and HTTPS are enabled.
To log in to the Web interface:

1. Use an Ethernet cable to connect the configuration terminal to an Ethernet port on the device.

2. Identify the IP address and mask of the device.

 If the device is not connected to the network, or no DHCP server exists on the network, the

device uses the default IP address and mask. The default mask is 255.255.0.0. The default
IP address is 169.254.xxx.xxx, where xxx.xxx depends on the rightmost two bytes of the
MAC address. Find the MAC address label on the device and use the following rules to
determine the rightmost two bytes for the IP address:

For example:

 If a DHCP server is available, the device obtains an IP address from the server. To identify

the address, log in to the device through the console port, and then execute the summary
command. The following is the sample output:

<Sysname> summary

Select menu option: Summary

IP Method: DHCP

IP address: 10.153.96.86

Setting up an IRF fabric

You can use IRF technology to connect and virtualize multiple switches into a large virtual switch
called an "IRF fabric" for flattened network topology, and high availability, scalability, and
manageability.

5. Configure basic IRF
settings

See HPE OfficeConnect 1950 12XGT 4SFP+ Switch (JH295A) User Guide.

6. Connect the physical
IRF ports

Connect physical IRF ports on switches. Use SFP+ transceiver modules and
fibers over a long distance, or use SFP+ network cables or twisted pair cables
over a short distance.

All switches except the master switch automatically reboot, and the IRF fabric
is established.

NOTE:

For the maximum IRF member devices supported by the switch, see the release notes that come
with the switch.

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 HPE OfficeConnect 1950 12XGT 4SFP+ Switch
(JH295A) User Guide.

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 switch can provide 10-GE IRF connections through 1/10GBASE-T Ethernet ports/SFP+ ports,

and you can bind several 1/10GBASE-T Ethernet ports/SFP+ ports to an IRF port for increased
bandwidth and availability.

Figure 21 and Figure 22 show the topologies of an IRF fabric made up of three switches. The IRF

port connections in the two figures are for illustration only, and more connection methods are
available.

Identifying physical IRF ports on the member switches

Identify the physical IRF ports on the member switches according to your topology and connection
scheme.

Table 8 shows the physical ports that can be used for IRF connection and the port use restrictions.

Table 8 Physical IRF port requirements

Planning the cabling scheme

Use twisted pair cables, SFP+ network cables, or SFP+ transceiver modules and fibers to connect
the IRF member switches. If the IRF member switches are far away from one another, choose SFP+
transceiver modules with optical fibers. If the IRF member switches are all in one equipment room,
choose twisted pair cables or SFP+ network cables. For more information about SFP+ network
cables and SFP+ transceiver modules, see "Appendix B Ports and LEDs."

The following subsections describe several recommended IRF connection schemes, and all these
schemes use a ring topology.

Connecting the IRF member switches in one rack

Use SFP+ network cables to connect the IRF member switches (9 switches in this example) in a rack
as shown in Figure 23. The switches in the ring topology (see Figure 24) 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 in different racks side by side to deploy a top of rack (ToR)
solution.

Figure 25 shows an example for connecting 9 top of rack IRF member switches by using SFP+

transceiver modules and optical fibers. The topology is the same as Figure 24.

Figure 25 ToR cabling

Configuring basic IRF settings

After you install the IRF member switches, power on the switches, and log in to each IRF member
switch (see HPE OfficeConnect 1950 12XGT 4SFP+ Switch (JH295A) User 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.
 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.

For more information about configuring basic IRF settings, see HPE OfficeConnect 1950 12XGT
4SFP+ Switch (JH295A) User Guide.

Connecting the physical IRF ports

Use twisted pair cables, SFP+ network cables, or SFP+ transceiver modules and fibers to connect
the IRF member switches as planned.

Wear an ESD wrist strap when you connect SFP+ network cables or SFP+ transceiver modules and
fibers. For how to connect them, see HPE SFP/SFP+/XFP Transceiver Modules and Network Cables
Installation Guide.
