NOTE:
The available chassis models and
accessories
vary by country and region. This document describes
only the preceding models. For the chassis models and
accessories available in your country or
region, contact the local HPE marketing personnel.
Safety recommendations
To avoid equipment damage or bodily injury, 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.
•
Ensure good ventilation at the installation site 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 power source voltage is as required.
•
To avoid electrical shocks, do not open the chassis while the switch is operating or when the
switch is just powered off.
•
To avoid ESD damage, wear an ESD wrist strap to hot-swap a power supply.
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 exhaust vents for ventilation.
•
The rack or workbench has a good ventilation system.
•
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
Maintain 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 different switch models, see technical
specifications in Hardware Information and 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 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 × 106 particles/m3
Dust particles ≥ 5 µm ≤ 3 × 104 particles/m3
Dust (suspension) ≤75 µm ≤0.4 mg/m3
Dust (sedimentation) 75 µm to 150 µm ≤15 mg/(m2h)
Sand ≥ 150 µm ≤300 mg/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 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.
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 protective earth (PE)
to filter interference from the power grid.
•
Keep the switch far away from radio transmitting stations, radar stations, and high-frequency
devices to make sure the EMI levels do not exceed the compliant range.
•
Use electromagnetic shielding when necessary. For example, use shielded interface cables.
•
To prevent signal ports from getting damaged by overvoltage or overcurrent caused by lightning
strikes, only route interface cables indoors.
Laser safety
WARNING!
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.
The switch is a Class 1 laser device.

Rack-mounting the switch
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 have been securely attached to the switch chassis.
3. Install cage nuts in the mounting holes in the rack posts.
No cage nuts are provided with the switch. Prepare them yourself.
4. One person holds the switch chassis and aligns the mounting brackets with the mounting holes
in the rack posts, and the other person attaches the mounting brackets to the rack with M6
screws.
M6 screws are provided only for switches shipped with mounting brackets. For switches not
shipped with mounting brackets, prepare M6 screws yourself.
5. Verify that the switch chassis is horizontal and secure.

Mounting the switch on a workbench
IMPORTANT:
•
Ensure 10 cm (3.9 in) of clearance around the chassis for heat dissipation.
•Do not place heavy objects on the switch.
If a standard 19-inch rack is not available, you can place you switch on a workbench.
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.
Mounting the switch on a wall
CAUTION
:
•
Before drilling holes in a wall, make sure no electrical lines exist in the wall.
•Leave a minimum clearance of 10 mm (0.39 in) around the chassis for heat dissipation.
Table 6 describes the switch models that support wall mounting and installation holes distances
required for wall-mounting the switch.

Figure 10 Screw anchor and screw
To mount the switch on a wall:
1. Mark two installation holes on the wall. Make sure the two holes are on the same horizontal line.
See Table 6 for the distance requirement between the two holes.
Figure 11 Installing the switch on a wall (1)
2. Drill two holes with a diameter of 6 mm (0.24 in) and a depth of 25 mm (0.98 in) at the marked
locations. Hammer the screw anchors into the wall and use a Phillips screwdriver to fasten the
screw into the screw anchor. Leave 1.5 mm (0.06 in) between the screw head and the wall for
hanging the switch.
Figure 12 Installing the switch on a wall (2)
3. Align the installation holes in the switch rear with the screws on the wall and hang the switch on
the screws. Make sure the port side faces down and the left and right sides are perpendicular to
the ground.

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 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
chassis views and power supply and grounding terminal positions in the following figures
are for
illustration only.
Grounding the switch with a grounding strip
WARNING
!
Connect the grounding cable to the grounding system in the equipment room. Do not connect it to a
fire main or lightning rod.
If a grounding strip is available at the installation site, use the grounding strip to ground the switch.
To ground the switch by using a grounding strip:
1. Attach the ring terminal end of the grounding cable to the grounding hole in the switch.
a. Remove the grounding screw from the grounding hole in the rear panel of the switch.
b. Attach the grounding screw to the ring terminal of the grounding cable.
c. Use a screwdriver to fasten the grounding screw into the grounding screw hole.

2. Connect the other end of the grounding cable to the grounding strip.
a. Cut the grounding cable to a length according to the distance between the switch and the
grounding strip.
b. Peel 20 mm (0.79 in) of insulation sheath by using a wire stripper.
c. Use the needle-nose pliers to bend the bare wire.
d. Hook the grounding cable to the post on the grounding strip, and use the hex nut to secure
the cable to the post.

Grounding the switch with a grounding conductor buried in
the earth ground
If the installation site has no grounding strips, but earth ground is available, hammer a 0.5 m (1.64 ft)
or longer angle iron or steel tube into the earth ground to serve as a grounding conductor.
The dimensions of the angle iron must be at least 50 × 50 × 5 mm (1.97 × 1.97 × 0.20 in). The steel
tube must be zinc-coated and its wall thickness must be at least 3.5 mm (0.14 in).
