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.
• When replacing FRUs, including power supplies, fan trays, and interface 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. To rack-mount your switch, make sure the following
requirements are met:
• 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 bottom
device from entering the top device.
• The rack is sturdy enough to support the switch and its accessories.
• The rack 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.
2
Temperature/humidity
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 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 a
nd 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)
EMI
Dust
NOTE:
Dust diameter ≥ 5 μm
≤ 3 x 104 (no visible dust on the tabletop over three days)
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, use the following guidelines:
• If AC power is used, use a single-phase three-wire power receptacle with protection earth (PE)
to filter interference from the power grid.
3
• 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!
Do not stare into any fiber port when the switch has power. The laser light emitted from the optical
fiber might hurt your eyes.
The switch is a Class 1 laser device.
Installation tools
No installation tools are provided with the switch. Prepare the following tools yourself:
• Phillips screwdriver.
• ESD wrist strap.
• Marker.

Connecting the grounding cable to the chassis
CAUTION:
Select grounding points as required. 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.
As a best practice, connect the grounding cable to the primary grounding point or auxiliary grounding
point 1. 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.
This section uses the primary grounding point on the HPE 5930-32 QSFP+/HPE 5930-32 QSFP+
TAA switch as an example.
To connect the grounding cable to a 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, as shown in Figure 10.

Attaching the slide rails to the rack
The procedures are the same for attaching 1U and 2U slide rails to the rack. This section uses the 1U
slide rails as an example.
To attach 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 17.
4. Rep
eat the preceding steps 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.

Mounting the switch in the rack
This task requires two people.
To mount the switch in the rack:
1. Wear an ESD wrist strap and make sure it makes good skin contact and is reliably 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. One person performs the following operations:
a. Supporting the bottom of the switch, aligns the chassis rails with the slide rails on the rack
posts.
b. Pushes the switch slowly to slide the chassis rails along the slide rails until the mounting
brackets are flush with the rack posts.
6. Another person uses screws (user-supplied) to attach the mounting brackets to the rack.
To secure the switch in the rack, make sure the front ends of the slide rails reach out of the
chassis rails.
The rack-mounting procedures are the same for the HPE 5930-32 QSFP+/HPE 5930-32 QSFP+
TAA/HPE 5930-2Slot+2QSFP+/HPE 5930-2Slot+2QSFP+ TAA switches. The following figures use
the HPE 5930-2Slot+2QSFP+/HPE 5930-2Slot+2QSFP+ TAA switch as an example.

NOTE:
To rack-mount the HPE 5930-4Slot/HPE 5930-4Slot TAA switch by using 2U high mounting
brackets and slide rails, use two screws and two cage nuts to attach each mounting bracket to the
rack. Determine the screw installation positions based on the distances between the square holes
on the rack posts. The screw installation positions in Figure 20 and
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 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.
