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.

4
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
views 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.

Attaching the slide rails to the rack
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 preceding 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.
Figure 8 Installing the slide rails
Mounting the switch in the rack
This task requires two people.

11
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 chassis 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:
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.
Installing a fan tray
Select appropriate fan trays as needed. For the optional fan trays and their specifications, see "Hot
swappable fan trays."

15
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).

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.

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.

Removing a power supply
CAUTION:
If the switch has two power supplies, removing one power supply does not affect the operation of the
switch. If the switch has only one power supply, removing the power supply powers off the switch.
To remove a 650W AC or 650W DC power supply from 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. Squeeze the tabs on the power cord connector with your thumb and forefinger, and pull the
connector out to remove the power cord, as shown in Figure 18.
3. Hold the handle on the power supply with one hand, pivot the latch on the power supply to the
right with your thumb, and pull the power supply part way out of the slot, as shown in Figure 19.
4. Supporting the power supply bottom with one hand, slowly pull the power supply out with the other
hand.
5. Put away the removed power supply in an antistatic bag for future use.
