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 a 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 the switch is powered 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 immediately
after the switch is powered off.
• To avoid ESD damage, wear an ESD wrist strap when hot-swapping a power supply.
Examining the installation site
The HPE OfficeConnect 1950 switches must be used indoors. You can mount your switch in a rack
or on a workbench, but make sure the following conditions exist:
• Adequate clearance is reserved at the air inlet and exhaust vents for ventilation.
1
• 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 a 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 as described in "Technical specifications."
• 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 introduce problems
such as loose captive screws or 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)
Dust
NOTE:
Dust diameter ≥ 5 μm
≤ 3 × 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.

NH3 0.05

)
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.
2
• 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.
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 HPE OfficeConnect 1950 switches are Class 1 laser devices.
Installation tools
The following installation tools are user supplied:
• Flat-blade screwdriver
• Phillips screwdriver
• ESD wrist strap
