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.

2

•

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 field replaceable units (FRUs), including 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.

Mount your switch in a rack and verify the following items:

•

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 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.

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 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 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 switch requirement for

cleanliness.

3

Table 2 Switch requirement for cleanliness

Substance Particle diameter Concentration limit

Dust particles ≥ 0.5 µm ≤ 1.8 × 107 particles/m3

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 do not exceed the concentration limits as shown in Table 3.

Table 3 Corrosive gas concentration limits

Gas Average concentration (mg/m3) Maximum concentration (mg/m3)

SO2 0.3 1.0

H2S 0.1 0.5

Cl2 0.1 0.3

HCI 0.1 0.5

HF 0.01 0.03

NH3 1.0 3.0

O3 0.05 0.1

NOX 0.5 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.

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.

4

•

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 a Class 1M laser device.

•

Disconnected optical fibers or transceiver modules might emit invisible laser light. Do not stare

into beams or view directly with optical instruments when the switch is operating.

Installation tools

No installation tools are provided with the switch. Prepare the following tools yourself:

•

Phillips screwdriver.

•

ESD wrist strap.

•

Marker.

Mounting brackets, chassis rails, and grounding cable

installation positions

The switch has one mounting position near the network ports and one mounting position near the

power supplies for mounting brackets.

The HPE 5945 48SFP28 8QSFP28 switch provides two grounding points: primary grounding point

(with a grounding sign) and auxiliary grounding point, as shown in Figure 17.

The HPE 5945 2-slot switch provides two grounding points: primary grounding point (with a

grounding sign) and auxiliary grounding point, as shown in Figure 18.

The HPE 5945 4-slot switch provides three grounding points: primary grounding point (with a

grounding sign), auxiliary grounding point 1, and auxiliary grounding point 2, as shown in Figure 19.
