8.
Either leave the default detection type (4ptdot3af), or, from the Detection Type
menu, select how the port detects the attached PD:
•
4ptdot3af: The port performs a 4-point resistive detection. This is the default
setting.
•
4ptdot3af+legacy: The port performs a 4-point resistive detection, and if
required, continues with legacy detection.
•
legacy: The port performs legacy detection.
9.
Either leave the default priority type (Low), or, from the Priority Type menu, select
the priority for the port in relation to other ports if the total power that the switch is
capable of delivering exceeds the total power budget:
•
Low: Low priority. This is the default setting.
•
Medium: Medium priority.
•
High: High priority.
•
Critical: Critical priority.
10.
Either leave the default power limit type (Class), or, from the Power Limit Type
menu, select how the port controls the maximum power that it can deliver:
•
None: For PoE+ (802.3at) ports, the port draws up to Class 0 maximum power
in low power mode. In high power mode, the following applies:
- PoE+ (802.3at) ports: The port draws up to Class 4 maximum power.
- PoE++ (802.3bt) ports: The port draws up to Class 8 maximum power.
•
Class: The port power limit is equal to the class of the attached PD. This is the
default setting. The upper limit is the power that a port can deliver to a PD. The
class is detected based on the PD that is attached to the port, and the following
applies:
-
PoE+ (802.3at) ports: Possible values are from Class 0 to Class 4.
-
PoE++ (802.3bt) ports: Possible values are from Class 0 to Class 8.
•
User: The port power limit is equal to the value that you specify in the Power
Limit (Watts) field.
11.
If you select User from the Power Limit Type, enter the maximum power (in W) that
the port can deliver in the Power Limit (Watts) field.
