The proper PoE switch or power adapter is selected, meeting
1
General
AP power supply and onsite environment requirements.
To ensure that the PoE power meets requirements, the PoE
power supply device and APs must be connected through
2
General
CAT5E and CAT6E network cables, and the cable length
cannot exceed 100 m.
Labels must be made for the PoE power cable to identify AP

General
locations.
Leave a 20 cm space between PoE power adapters to ensure

General
The PoE switch is correctly grounded with the ground cable.
Reserve a few downlink network interfaces for the PoE
switch (for example, connect at most 20 APs to a 24-port
6
General
switch) for future capacity expansion.
You are advised to configure dual power modules for a PoE
7
General
switch for power redundancy backup and providing power
for more APs.
The AP installation positions comply with the network
planning report and APs cannot be installed in environments
with strong electrical or magnetic interference or corrosive
1
General
materials. If the onsite environment does not meet
requirements, adjust the AP installation positions properly.
