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, unplug 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 proper 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.
• When replacing FRUs, including power supplies and fan trays, wear an ESD-preventive wrist strap
to avoid damaging the units.

Examining the installation site
The HP FlexFabric 5930 switches must be used indoors.
Mount your switch in a rack and make sure:
• Adequate clearance is reserved at the air inlet and exhaust 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 bottom
device from entering the top device.
• The rack is sturdy enough to support the switch and its accessories.
• The rack is well earthed.
To ensure normal 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 appropriate temperature and humidity in the equipment room.
• Lasting high relative humidity can cause poor insulation, electricity creepage, 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 "Appendix A Chassis
v
iews and technical specifications."
Cleanness
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 μm
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.

EMI
All electromagnetic interference (EMI) sources, from outside or inside of the switch and application
system, adversely affect the switch in a conduction pattern of capacitance coupling, inductance coupling,
electromagnetic wave radiation, or common impedance (including the grounding system) coupling. To
prevent EMI, take the following actions:
• 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 switch far away from radio transmitting stations, radar stations, and high-frequency
devices.
• Use electromagnetic shielding, for example, shielded interface cables, when necessary.
• Route interface cables only indoors to prevent signal ports from getting damaged by overvoltage or
overcurrent caused by lightning strikes.
Laser safety
The HP FlexFabric 5930 switches are Class 1 laser devices.
W
ARNING!
Do not stare into any fiber port when the switch has power. The laser li
g
ht emitted from the optical fiber
might hurt your eyes.

Connecting the grounding cable to the chassis
CAUTION:
The primary grounding point and auxiliary grounding point 1 are located on the left side panel. If you use
one of these grounding points, you must connect the grounding cable to the grounding point before you
mount the switch in the rack.
HP recommends that you use the primary grounding point or auxiliary grounding point 1 because the
grounding cable and grounding screw that come with the switch are suitable only for these two
grounding points.
To use auxiliary grounding point 2, prepare a grounding cable yourself.
To connect the grounding cable to a chassis grounding point, for example, the primary grounding point:
1. Choose a grounding point.
2. Unpack the grounding cable and grounding screws.
You can use the cable and screws shipped with the switch only for connecting to the primary
grounding point or auxiliary grounding point 1.
3. Align the two-hole grounding lug at one end of the cable with the grounding holes of the
grounding point, insert the grounding screws into the holes, and tighten the screws with a
screwdriver to attach the grounding lug to the chassis, as shown in Figure 6.

1. Identify the rack attachment position for the slide rails.
2. Install cage nuts (user-supplied) in the mounting holes in the rack posts.
3. Align the screw holes in one slide rail with the cage nuts in the rack post on one side, and use
screws (user-supplied) to attach the slide rail to the rack, as shown in Figure 8.
4. Repeat the pr
eceding step to attach the other slide rail to the rack post on the other side.
Keep the two slide rails at the same height so the slide rails can attach into the chassis rails.

To mount the switch in the rack:
1. Wear an ESD-preventive wrist strap and make sure it makes good skin contact and is well
grounded.
2. Verify that the mounting brackets and chassis rails have been securely attached to the switch
chassis.
3. Verify that the slide rails have been correctly attached to the rear rack posts.
4. Install cage nuts (user-supplied) to the front rack posts and make sure they are at the same level as
the slide rails.
5. Supporting the bottom of the switch, align the chassis rails with the slide rails on the rack posts, as
shown in Figure 9. Work with another person to slide the chass
is rails along the slide rails until the
mounting brackets are flush with the rack posts.
6. Use screws (user-supplied) to attach the mounting brackets to the rack, as shown in Figure 10.
To
secure the switch in the rack, make sure the front ends of the slide rails reach out of the chassis
rails.

Grounding the switch
W
ARNING!
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 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 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.

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 at one end of the grounding cable to a grounding point on the
switch chassis (see "Connecting the grounding cable to the chassis").
2. Remove the hex nut of a grounding post on the grounding strip.
3. Attach the ring terminal at the other end of the grounding cable to the grounding strip through the
grounding post, and fasten the ring terminal with the removed hex nut.

HP recommends that you use the primary grounding point or auxiliary grounding point 1 on the HP
FlexFabric 5930-32QSFP+/HP FlexFabric 5930-32QSFP+ TAA switch, because the grounding cable
and grounding screw provided with the switch are applicable only to these two grounding points.
To use auxiliary grounding point 2, prepare a grounding cable yourself. The connection method is the
same as connecting to the other two grounding points.
Grounding the switch by using the AC power cord
If the installation site has no grounding strips, you can ground an AC-powered switch through the
protective earth (PE) wire of the power cord, but must make sure:
• The power cord has a PE terminal.
• The ground contact in the power outlet is securely connected to the ground in the power distribution
room or on the AC transformer side.
• The power cord is securely connected to the power outlet.

NOTE:
If the
g
round contact in the power outlet is not connected to the ground, report the problem and reconstruc
t
the grounding system.

NOTE:
To guarantee the grounding effect, use the grounding cable provided with the switch to connect to the
grounding strip in the equipment room as long as possible.
Installing/removing a fan tray
CAUTION:
Each of the HP FlexFabric 5930 switches requires two fan trays of the same model to function correctly.
• Do not operate the system with one failed fan tray for more than 24 hours.
• Do not remove the failed fan tray until you are ready for replacing it.
• Do not operate the system without any fan tray for more than 2 minutes.
• Do not operate the system outside of the temperature range 0°C to 45°C (32°F to 113°F) degrees.
Failure to comply with these operating requirements might void the warranty.

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-preventive wrist strap and make sure it makes good skin contact and is well
grounded.
2. Unpack the fan tray and check that the fan tray model is correct.
3. Grasp the handle of the fan tray with one hand and support the fan tray bottom with the other, and
slide the fan tray along the guide rails into the slot until the fan tray seats in the slot and has a firm
contact with the backplane (see callout 1 in Figure 13).
4. Fasten the
captive screw on the fan tray with a Philips screwdriver until the fan tray is securely
attached in the chassis (see callout 2 in Figure 13).
If the captive screw cannot be tightly fastened, check the installation of the fan tray.

Installing/removing a power supply
W
ARNING!
• The switches do not support intermixing of AC and DC power supplies.
• In power redundancy mode, you can replace a power supply without powerin
g
off the switch but mus
t
strictly follow the installation and procedures in Figure 14 and Figure 15 to avoid any bodily injury or
damage to the switch.
The HP FlexFabric 5930 switches come with both power supply slots empty and the power filler modules
as accessories.
You can install one or two power supplies for these switches as needed. For more information about the
power supplies available for the switches, see "Hot swappable ."
Figure 14 Installation procedure
Figure 15 Removal procedure
NOTE:
The HP A58x0AF 650W AC power supply and the HP A58x0AF 650W DC power supply are referred to
as the 650W AC power supply and the 650W DC power supply throughout this installation guide.
Installing a power supply
CAUTION:
• Follow the forward inertia of the power supply when inserting it into the chassis, and make sure the
power supply has firm contact with the connectors on the backplane.
• To prevent damage to the connectors inside the switch chassis, insert the power supply gently. If you
encounter a hard resistance while inserting the power supply, pull out the power supply and insert it
again.
• If only one power supply is installed, install a power filler module in the empty power supply slot for
good ventilation of the switch.
To install a 650W AC power supply or 650W DC power supply into the HP FlexFabric 5930 switch:
1. Wear an ESD-preventive wrist strap and make sure it makes good skin contact and is well
grounded.
2. Unpack the power supply and check that the power supply model is correct.
3. Correctly orient the power supply with the power supply slot (see Figure 16), grasp
the handle of
the power supply with one hand and support its bottom with the other, and slide the power supply
slowly along the guide rails into the slot.
Page 19
17
The slot is foolproof. If you cannot insert the power supply into the slot, re-orient the power supply
rather than use excessive force to push it in.

Setting up an IRF fabric
You can use HP IRF technology to connect and virtualize HP FlexFabric 5930 switches into a large virtual
switch called an "IRF fabric" for flattened network topology, and high availability, scalability, and
manageability.
To set up IRF links between multiple switches, use QSFP+ ports.
IRF fabric setup flowchart
Figure 32 IRF fabric setup flowchart
To set up an IRF fabric:

Step Description
1. Plan IRF fabric setup.
Plan the installation site and IRF fabric setup parameters:
• Planning IRF fabric size and the installation site
• Identifying the master switch and planning IRF member IDs
• Planning IRF topology and connections
• Identifying physical IRF ports on the member switches
• Planning the cabling scheme
2. Install IRF member
switches.
See "Installing the switch in a 19-inch rack".
3. Connect ground wires
and power cords.
See "Grounding the switch" a
nd "Connecting the power cord."
4. Power on the switches.
N/A
5. Configure basic IRF
settings.
See HP FlexFabric 5930 Switch Series IRF Configuration Guide.
6. Connect the physical
IRF ports.
Connect the physical IRF ports on switches. Use QSFP+ transceiver modules and
fibers for long-distance connection. Use QSFP+ 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.
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 top-of-rack (ToR) access
solution for a data center.
As your business grows, you can plug HP FlexFabric 5930 switches into the IRF fabric to increase the
switching 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 manag i ng all member switches in the IR F fab ric.
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.
Page 32
30
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 master election, see
H
P
FlexFabric 5930 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.
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 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.
The HP FlexFabric 5930-32QSFP+/HP FlexFabric 5930-32QSFP+ TAA switch can provide 40-GE IRF
connections through QSFP+ ports. You can bind several QSFP+ ports to an IRF port for increased
bandwidth and availability.
NOTE:
• Figure 33 an
d Figure 34 show the topologies of an IRF fabric made up of three HP FlexFabric
5930-32QSFP+/HP FlexFabric 5930-32QSFP+ TAA switches that use QSFP+ ports for IRF connections.
• The IRF port connections in the two fi
g
ures are for illustration only, and more connection methods are
available.

Identifying physical IRF ports on the member switches
Identify the QSFP+ ports to be used for IRF connections on the member switches according to your
topology and connection scheme.
All QSFP+ ports on the HP FlexFabric 5930 switch can be used for IRF connections.
Planning the cabling scheme
For the HP FlexFabric 5930 switches, use QSFP+ cables, or QSFP+ transceiver modules and fibers to
connect the IRF member switches. If the IRF member switches are far away from one another, choose the
QSFP+ transceiver modules with optical fibers. If the IRF member switches are all in one equipment room,
choose QSFP+ cables. For more information about available QSFP+ cables and transceiver modules,
see "QSFP+ port."
T
he following subsections describe several HP recommended IRF connection schemes, and all these
schemes use a ring topology.
Connecting the IRF member switches in one rack
Use short-haul and long-haul QSFP+ cables to connect the IRF member switches (four switches in this
example) in a rack as shown in Figure 35. T
he switches in the ring topology (see Figure 36) 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 37
shows an example for connecting four top of rack IRF member switches by using QSFP+ cables,
and QSFP+ transceiver modules, and optical fibers. The topology is the same as Figure 36.
Figure 37 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 HP FlexFabric 5930 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.

Use QSFP+ cables or QSFP+ transceiver modules and 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 HP
FlexFabric 5930 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 5.

Appendix D Cooling system
The cooling system of the HP FlexFabric 5930 switches comprises the ventilation holes in the chassis, fan
trays, and built-in fans of hot swappable power supplies. To guarantee that this cooling system can
effectively work, you must consider the site ventilation design when you plan the installation site for the
switches.
The fan trays in the HP FlexFabric 5930-32QSFP+/HP FlexFabric 5930-32QSFP+ TAA switch must be the
same type: LSWM1HFANSC or LSWM1HFANSCB.
• When LSWM1HFANSC fan trays are used, cool air flows in through the air vents in the fan tray
panel and the power supply panels, circulates through the chassis and the power supplies, and
exhausts at the network port side, as shown in Figure 43.
• W
hen LSWM1HFANSCB fan trays are used, cool air flows in through the air vents in the network
port-side panel and the power supply panels, circulates through the chassis and the power supplies,
and exhausts through the air vents in the fan tray panels, as shown in Figure 44.
