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.
