Preparing for installation
Safety recommendations
To avoid any equipment damage or bodily injury caused by improper use, read the following safety
recommendations before installation. The recommendations do not cover every possible hazardous
condition.
•Do not store the switch without power too long due to the storage requirement for the electrolytic
capacitor in the switch.
•Take proper anti-interference measures because the switch might cause radio interference as a
class-A product.
•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 proper ventilation of the equipment room and keep the air inlet and outlet vents of the switch
free of obstruction.
•Make sure that 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.
•The accessories shipped with the switch, including but not limited to power cables, are intended
only for the switch. Please do not use them for other products.
Examining the installation site
The HP 1910 switches must be used indoors. You can mount your switch in a rack or on a workbench, but
make sure:
•Adequate clearance is reserved (at least 5 cm or 1.97 in) at the air inlet and exhaust vents for
ventilation.
•The rack or workbench has a good ventilation system.
•The rack or workbench is sturdy enough to support the switch and its accessories.
•The rack or workbench is well earthed.
To ensure normal 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 creepage, mechanical property
change of materials, and metal corrosion.

2
•Lasting low relative humidity can cause washer contraction and ESD and bring problems including
loose captive 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 B Technical
specifications.
Cleanness
Dust buildup on the chassis may 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 ≤3 x 104 (no visible dust on the tabletop over three days)
NOTE:
Dust diameter ≥5 μm
The equipment room must also meet strict limits on salts, acids, and sulfides to eliminate corrosion and
premature aging of components, as shown in Table 3.
Table 3 Harmful gas limits in the equipment room
Gas Maximum concentration (mg/m3)
SO20.2
H2S 0.006
NH30.05
Cl20.01
EMI
All electromagnetic interference (EMI) sources, from outside or inside of the switch and application
system, adversely affect the switch in a conduction pattern of capacitance coupling, inductance coupling,
electromagnetic wave radiation, or common impedance (including the grounding system) coupling. To
prevent EMI, take the following actions:
•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.
•Route interface cables only indoors to prevent signal ports from getting damaged by overvoltage or
overcurrent caused by lightning strikes.
