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 powering on the switch.
•
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 field replaceable units (FRUs), including expansion cards, power supplies, and
fan trays, 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
For correct operation and long service life of your switch, maintain the temperature and humidity in
the equipment room at acceptable ranges.
•
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 of the switch, see technical specifications in
Hardware Information and Specifications.

3
Cleanliness
Dust buildup on the chassis might cause electrostatic adsorption and dust corrosion, resulting in
poor contact of metal connectors and contact points. This might shorten the device's lifetime and
even cause device failure in the worst case. Table 2 describes the dust concentration limits in the
equipment room.
Table 2 Dust concentration limits in the equipment room
Substance Particle diameter Concentration limit
Dust particles ≥ 0.5 µm ≤ 3.5 × 106particles/m3
Dust particles ≥ 5 µm ≤ 3 × 104particles/m3
Dust (suspension) ≤75 µm ≤0.2 mg/m3
Dust (sedimentation) 75 µm to 150 µm ≤1.5 mg/(m2h)
To maintain cleanliness in the equipment room, follow these guidelines:
•
Keep the equipment room away from pollution sources. Do not smoke, eat, or drink in the
equipment room.
•
Use double-layer glass in windows and seal doors and windows with dust-proof rubber strips.
Use screen doors and window screens for doors and windows open to the outside and make
sure the external windows are air tight.
•
Use dustproof materials for floors, walls, and ceilings and use wallpaper or matt paint that does
not produce powders.
•
Clean the equipment room regularly and clean the air filters of the rack each month.
•
Wear ESD clothing and shoe covers before entering the equipment room, keep the ESD
clothing and shoe covers clean, and change them frequently.
Corrosive gas limit
Corrosive gases can accelerate corrosion and aging of metal components. Make sure the corrosive
gases in the equipment room do not exceed the concentration limits as shown in Table 3.
Table 3 Corrosive gas concentration limits in the equipment room
Gas Average concentration (mg/m3) Maximum concentration (mg/m3)
SO20.3 1.0
H2S 0.1 0.5
Cl20.1 0.3
HCI 0.1 0.5
HF 0.01 0.03
NH31.0 3.0
O30.05 0.1
NOX0.5 1.0
CAUTION:
As a best practice, control the
corrosive gas concentrations in the equipment room at their
average
values
. Make sure the corrosive gas concentrations do not exceed 30 minutes per day at their
maximum values.

4
To control corrosive gases, use the following guidelines:
•
As a best practice, do not build the equipment room in a place with a high concentration of
corrosive gases.
•
Make sure the equipment room is not connected to sewer, vertical shaft, or septic tank pipelines
and keep it far away from these pipelines. The air inlet of the equipment room must be away
from such pollution sources.
•
Use environmentally friendly materials to decorate the equipment room. Avoid using organic
materials that contains harmful gases, such as sulfur or chlorine-containing insulation cottons,
rubber mats, sound-proof cottons, and avoid using plasterboards with high sulfur concentration.
•
Place fuel (diesel or gasoline) engines separately. Do not place them in the same equipment
room with the device. Make sure the exhausted air of the engines will not flow into the
equipment room or towards the air inlet of the air conditioners.
•
Place batteries separately. Do not place them in the same room with the device.
•
Employ a professional company to monitor and control corrosive gases in the equipment room
regularly.
EMI
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.
•
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.
•
To prevent signal ports from getting damaged by overvoltage or overcurrent caused by lightning
strikes, route interface cables only indoors.
Laser safety
WARNING
!
The switch is Class 1 laser device.
Do not stare into any fiber port when the switch has power. The
laser light emitted from the optical fiber might hurt your eyes.

Mounting the switch on a workbench
IMPORTANT:
•
Reserve a minimum of 10 cm (3.9 in) of clearance around the chassis for heat dissipation.
•Do not place heavy objects on the switch.
To mount the switch on a workbench:
1. Verify that the workbench is sturdy and reliably grounded.
2. Place the switch with bottom up, and clean the round holes in the chassis bottom with dry cloth.
3. Attach the rubber feet to the four round holes in the chassis bottom.
4. Place the switch with upside up on the workbench.
Grounding the switch
WARNING
!
Correctly connecting the 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 to minimize the potential for system damage, maximize the safety at the
site, and minimize EMI susceptibility of the system.
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
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 strip
in the equipment room. Do not connect it to a
fire main or lightning rod.
•
To guarantee the grounding effect and avoid switch damage, use the grounding cable provided
with the switch to connect the switch to a grounding strip in the equipment room.
If a grounding strip is available at the installation site, connect the grounding cable to the grounding
strip.
Connecting the grounding cable to the chassis
1. Remove the grounding screw from the rear panel of the switch chassis.
2. Use the grounding screw to attach the ring terminal of the grounding cable to the grounding
screw hole. Fasten the screw.

16
IMPORTANT:
Orient the grounding cable as shown in
Figure 15 so you can easily install or remove the
expansion card.

Connecting the grounding cable to a grounding strip (1)
This method is applicable to the HPE 5140 24G PoE+ 4SFP+ 1-slot HI and HPE 5140 48G PoE+
4SFP+ 1-slot HI switches.
To connect the grounding cable to a grounding strip:
1. Remove the hex nut of a grounding post on the grounding strip.
2. Cut the grounding cable to a length required for connecting to the grounding strip.
3. Attach a ring terminal to the grounding cable:
a. Use a wire stripper to strip 5 mm (0.20 in) of insulation off the end of the grounding cable.
b. Slide the heat-shrink tubing onto the cable and insert the bare metal part into the end of the
ring terminal.
c. Use a crimper to secure the metal part of the cable to the ring terminal.
d. Slide the heat-shrink tubing down the cable until the tube covers the joint.
e. Use a heat gun to shrink the tubing around the cable.
