Safety recommendations
To avoid any equipment damage or bodily injury caused by incorrect 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 or when the
switch is just powered off.

Examining the installation site
The switch must be used indoors.
Mount your switch in a rack and verify the following items:
Temperature/humidity
Adequate clearance is reserved at the air inlet and outlet vents for ventilation.
The rack 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 devices from entering the top device.
The rack is sturdy enough to support the switch and its accessorie s.
The rack is reliably grounded.
T o ensure co rrect operation and long service life of your switch, install it in an environment that meets
the requirements described in the following subsections.
Maintain appropriate temperature and humidity in the equipment room.
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 problems
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 for the switch, 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.
Table 2 Dust concentration limit in the equipment room
Substance Concentration limit (particles/m³)
Dust 3 x 104 (no visible dust on the tabletop over three days)
NOTE:
Dust diameter 5 ȝm
The equipment room must also meet limits on salts, acids, and sulfides to eliminate corrosion and
premature aging of components, as shown in Table 3.

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.
To prevent EMI, perform the following tasks:
If AC power is used, use a single-phase three-wire po wer receptacle with prote ction earth (PE)
to filter interference from the power grid.
Keep the switch far away from radio transmitting stations, radar stations, and high-frequency
devices.
Use electromagnetic shielding, for example, shielded interface cables, when necessary.
Laser safety
WARNING!
x The switch is a Class 1 laser device.
x Do not stare into any fiber port when the switch has power. The laser light emitted from the optical
fiber might hurt your eyes.

Grounding the switch
WARNING!
Correctly connecting the switch grounding cable is crucial to lightning protection and EMI protection.
The power input end of the switch has a noise filter , whose central grou nd 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 a switch by using a grounding strip at the installation site or the AC power cord
connected to the switch.
NOTE:
The power and grounding terminals in this section are for illustration only.
Grounding the switch with a grounding strip
WARNING!
Connect the grounding cable to the grounding system in the equipment room. Do not connect it to a
fire main or lightning rod.
If a grounding strip is available at the installation site, connect the grounding cable to the grounding
strip.
To connect the grounding cable:
1. Attach the two-hole grounding lug of the grounding cable to a grounding point on the chassis.
For more information, see "Connecting the grounding cable to the chassis."

Installing/removing fan trays
CAUTION:
The HPE FlexFabric 5950 switches have six fan tray slots. To ensure good ventilation of the switch,
follow these guidelines:
x You must install six fan trays of the same model for the switch: HPE X712 HV2 fan tray or HPE
X711 HV2 fan tray.
x Make sure all slots have a module or filler panel installed when the switch is operating.
x Do not remove multiple fan trays at the same time. Remove the fan trays one by one and finish
replacing a fan tray within 3 minutes..
Installing a fan tray
CAUTION:
To prevent damage to the fan tray or the connectors on the backplane, insert the fan tray gently. If
you encounter a hard resistance while inserting the fan tray, pull out the fan tray and insert it again.
To install a fan tray:
1. Wear an ESD wrist strap and make sure it makes good skin contact and is reliably grounded.
2. Unpack the fan tray and verify that the fan tray model is correct.
15
Page 20
3. Orient the fan tray with the "TOP" mark on top. Grasp the handle of the fan tray and slide the fan
tray along the guide rails into the slot until the fan tray seats in the slot and the fan tray
connector has a firm contact with the backplane. See Figure 19.
Figure 19

When the switch is powered on for the first time, use the fan prefer-direction command to configure
the airflow direction of the fan tray as the preferred airflow direction of the switch. If the fan tray
airflow direction and the preferred airflow direction are not the sa me, the system generates traps a nd
logs. By default, the preferred airflow direction is from the power module side to the port side.
For more information about the fan prefer-direction command, see HPE FlexFabric 5950 Switch

Accessing the switch for the first time
Setting up the configuration environment
You can access the switch through the serial console port or the mini USB console port. As a best
practice, use the serial console port to access the switch. To access the switch through the mini USB
console port, you need to prepare a mini USB console cable yourself.
The example uses a console cable to connect a console terminal (PC) to the serial console port on
the switch.
Figure 29 Connecting the serial console port to a terminal
Connecting the console cable
A serial con sole cable is a n 8-core cabl e, with a crimped RJ-45 conne ctor at on e end for connectin g
to the serial console port of the switch, and a DB-9 female connector at the other end for connecting
to the serial port on the console terminal.

Setting up an IRF fabric
You can use Hewlett Packard Enterprise 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.

See "Grounding the switch" a
N/A
See HPE FlexFabric 5950 Switch Series IRF Configuration Guide.
Connect the physical IRF ports on switches. Use QSFP28/QSFP+/SFP+
transceiver modules and fibers for long-distance connection. Use
QSFP28/QSFP+/QSFP+ to SFP+/SFP+ network 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.
nd "Connecting the power cords."
Planning IRF fabric size and the installation site
Determine the number of required IRF member switches, depending on the user density and
upstream bandwidth requirements. The switching capacity of an IR F 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 ra cks to implement the top-of-rack (ToR) access
solution for a data center.
As your business grows, you can add member switches into the IRF fabri c to increase the swit ching
capacity without any topology change or replacement.
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 command line interface of the master switch.
NOTE:
IRF member switches will 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 maste
election, see HPE FlexFabric 5950 Switch Series IRF Configuration 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.
28
Page 33
Planning IRF topology and connections
You can create an IRF fabric in daisy chain topology, or more reliably, ring topology. In ring topology ,
the failure of one IRF link does not cause the IRF fabric to split as in daisy chain topology . Rather , 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 IRF port connections in the two figures are for illustration only, and more connection methods
are available.

You can set up IRF links between HPE FlexFabric 5950 switches as follows:
Use QSFP28 transceiver modules and fibers or QSFP28 network cables to connect the
QSFP28 ports on the switches for 100-GE IRF physical connections.
Use QSFP+ transceiver modules and fibers or QSFP+ network cables to connect the QSFP28
ports on the switches for 40-GE IRF physical connections.
Use 40G QSFP+ to 4 x 10G SFP+ network cables to connect a QSFP28 port to four ports that
have a transmission rate of 10 Gbps or above.
Connect the SFP+ ports on the switches for 10-GE physical connections.
You can bind several ports to an IRF port for increased bandwidth and availability.
Identifying physical IRF ports on the member switches
Identify the QSFP28 and SFP+ ports for IRF connections on the member switche s according to your
topology and connection scheme.
All the QSFP28 and SFP+ ports on the HPE FlexFabric 5950 switch can be used for IRF
connections.
Planning the cabling scheme
You can use the QSFP28/QSFP+/QSFP+ to SFP+/SFP+ network cables or QSFP28/QSFP+/SFP+
transceiver modules and optical fibers to connect the HPE FlexFabric 5950 switches for IRF
connections.
If the IRF member switches are far away from one another, use QSFP28/QSFP+/SFP+ transceiver
modules and optical fibers for IRF connections. If the IRF member switches are all in one equipment
30
Page 35
room, use QSFP28/QSFP+/QSFP+ to SFP+/SFP+ network cables for IRF connections. For more
information about available transceiver modules and cables, see "Appendix C Ports and LEDs."
The follo
wing subsections describe several IRF connection schemes. As a best p ractice, use the ring
topology for IRF connections.
Connecting the IRF member switches in one rack
Figure 37 shows an example for connecting four IRF member switches in a rack by using QSFP28
network cables and QSFP28 transceiver modules and optical fibers. The switches in the ring

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 FlexFabric 5950 Switch Series Fundamentals Configuration 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.
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 HPE FlexFabric 5950 Switch Series
IRF Configuration Guide.
Connecting the physical IRF ports
CAUTION:
Wear an ESD wrist strap when you connect cables or transceiver modules and optical fibers. For
more information, see the installation guide for the transceiver modules.
Use cables or transceiver modules and optical fibers to connect the IRF member switches as
planned.
Accessing the IRF fabric to verify the configuration
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 HPE FlexFabric 5950 Switch Series Fundamentals Configuration Guide.)
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 8.

Appendix D Cooling system
The cooling system of the switch includes air vents in the chassis, fan trays, and fans of power
modules. To guarantee effective operation of this cooling system, you must consider the site
ventilation design when you plan the installation site for the switch.
Y ou must inst all six fan trays of the same model for the switch: HPE X712 HV2 fan tray or HPE X711
HV2 fan tray.
When the HPE X712 HV2 fan trays are used, ambient air flows in through th e air vents in the fan
tray and power module panels, carries heat dissipated from the chassis and power modules,
and exhausts through the air vents in the port-side panel, as shown in Figure 46.
