Electromagnetic interference
Electromagnetic interference can affect the device internal capacitance,
inductance, in order to reduce electromagnetic interference factor cause
adverse effect, please pay attention to the following of items:
Supply power system adopt necessary anti power grid interference
measure;
PoE switch should be far away from high frequency power, high current
device, such as wireless launch pad;
If necessary, please make electromagnetic shielding measure
Lighting protection requirement
When lighting strike, in the moment will have a strong current, the air on
the discharge path will be instantly heated to 20000 celsius degrees, in the
moment high current enough to cause fatal damage to electronic
equipment.
In order to reach better lightning protection effect, please not the following:
Make sure the rack is in good touch with the ground;
Make sure the power socket is in good touch with the ground;
Reasonable wiring to avoid internal lightning;
Outdoor wiring, it is recommended to use signal lightning protector;
Installation platform requirment
POE switch is installed in a rack or on another horizontal workbench,
Please note the following:
Make sure rack or workbench smooth and steady, secure, it can bear
5.5kg weight at least;
Make sure the rack has a good cooling system,or keep indoor well-
ventilated;
Make sure the rack is well grounded, power socket and POE switch don’t
exceed 1.5meter
Installation tools ready
During installation, may be used screwdrivers, antistatic wrist strap, network
cable , fiber tools, please the user self-prepare;
