Safety recommendations
To avoid possible bodily injury and equipment damage, read the
following safety recommendations before installing an H3C S5120-EI
series. Note that the recommendations do not cover every possible
hazardous condition.
z Turn off all power and remove all the power cables before
opening the chassis. Before cleaning, unplug the power plug first
and do not clean with a wet cloth or liquid.
z Keep the chassis clean and dust-free and away from water or a
damp environment; do not place on an unstable case or desk.
z Ensure proper ventilation of the equipment room and keep the
ventilation vents of the switch free of obstruction.
z Make sure that the operating voltage is the same as labeled on
the switch.
z When replacing interface modules, wear ESD-preventive gloves
to avoid damaging the cards.
For more compliance and safety information, see “Appendix
Compliance and safety information

Examine the installation site
The H3C S5120-EI series can only be used indoors. Make sure that
the floor can support the weight of the cabinet and the switch chassis.
