Figure 15 Connecting IoT access units to the AP
Connecting the AP to the power source
You can supply power to the AP by using a local power source, a power injector, or through
802.3af/802.at PoE. To power the AP through PoE, use 802.at PoE as a best practice. When the AP
has IoT access units connected to it, 802.3af PoE cannot satisfy the maximum power requirements
of the AP.
Check before power-on
Check the following items before powering on the AP:
•
To power the AP with local power, make sure the local power supply is reliably grounded.
•
To power the AP through PoE, make sure the PoE power supply (PSE) is reliably grounded.
•
The AP is to be connected only to PoE networks without routing to the outside plant.
Connecting the PoE power supply
CAUTION:
•
Only the GE1 port on the AP supports 802.3af/at PoE.
•
To avoid port damage, do not use the GE2/IoT port as a PoE port to receive power.
•
To use both Ethernet ports on the AP, connect an Ethernet cable to one port for PoE connection
first, and then connect the other after the AP is powered on.
Use an Ethernet cable to connect the Ethernet port on the AP to a port on a switch that supports
PoE.
