detects that the attached PD requests more power than IEEE 802.3af but is not an
IEEE 802.3at Class 4 device, the PD does not receive power from the switch.
11.
From the
Power Limit Type
menu, select how the port controls the maximum power that it
can deliver:
•
None
. The port draws up to Class 0 maximum power in low power mode and up to
Class 4 maximum power in high power mode.
•
Class
. The port power limit is equal to the class of the attached PD.
•
User
. The port power limit is equal to the value that is specified in the
Power Limit
(mW)
field. This is the default setting.
Note:
If a PD does not report its class correctly, use of these options can
preserve additional PoE power by preventing the switch from
delivering more power than the PD requires. However, depending on
which option you select, a PD that does not report its class correctly
might not power up at all.
12.
In the
Power Limit (mW)
field, enter the maximum power (in mW) that the port can deliver.
The range is 3,000–30,000 mW. The default is 30,000 mW.
13.
From the
Detection Type
menu, select how the port detects the attached PD:
•
IEEE 802
. The port performs a 4-point resistive detection. This is the default setting.
•
4pt802.3af+legacy
. The port performs a 4-point resistive detection, and if required,
continues with legacy detection.
•
Legacy.
The port performs legacy detection.

From the
Timer
Schedule
menu, select a timer schedule or select
None
