PoE Considerations
The switch prioritizes the PoE and PoE+ power that it supplies in ascending port
order (from port 1 to port 8), with a total power budget of 120 watts. If the power
requirements for the attached powered devices (PDs) exceed the total power
budget of the switch, the PD on the highest-numbered port is disabled to make
sure that the PDs that are connected to the higher-priority, lower-numbered ports
are supported first.
Just because a PD is listed as an 802.3at PoE powered device does not
necessarily mean that it requires the maximum power limit of the specification.
Many PDs require less power, allowing all eight PoE ports to be active
simultaneously.
The following table describes the PoE classes and switch allocations.

PoE Max LED
The maximum PoE power that the switch can deliver to all attached powered devices
(PDs) is 120 watts total, with a maximum power to each port of 30 watts. (For more
information, see
)
The PoE Max LED indicates the status of the PoE power that the switch can deliver to
all attached PDs, as follows:
Solid amber
. Less than 7W of PoE power is available on the switch.
Blinking amber
. The PoE Max LED was lit solid in the previous two minutes.
Sufficient (more than 7W of) PoE power is available on the switch (the LED is
off).
