2

From the navigation tree, choose Edit.

3

In the Edit tree, double-click Unit.

4

In the work area, click the PoE tab.

5

In the UsageThreshold%, type a value.

6

Variable definitions

Use the data in the following table to display and manage PoE for a switch unit.

Variable Value
Power(watts) Displays the total power (in watts) available to the switch.
OperStatus

Displays the power state of the switch:

  • on
  • off
  • faulty
Consumption
Power(watts)
Displays the power (in watts) being used by the switch.
UsageThreshold%

Lets you set a percentage of the total PoE power usage at which the switch sends a warning trap message. If the PoE power usage exceeds the threshold and SNMP traps are appropriately configured, the switch sends the pethMainPowerUsageOnNotification trap. If the power consumption exceeds and then falls below the threshold, the switch sends the pethMainPowerUsageOffNotification trap.


Attention

You must enable the traps (NotificationControlEnable) to receive a power usage trap.

Notification
ControlEnable
Lets you enable or disable sending traps if the switch power usage exceeds the percentage set in the UsageThreshold field.
PowerDevice
DetectType

Lets you set the power detection type that the switch uses to detect a request for power from a device connected to all ports on the switch:

• 802.3af
• 802.3af and legacy


Attention

The default setting is 802.3af. Ensure that this setting matches the setting for the detection type used by the powered devices on this switch.

PowerPresent Specifies the currently used power source. Available power sources are AC and DC.

A value of acOnly indicates that the only power supply is AC.
A value of dcOnly indicates that the only power supply is DC.
A value of acDc indicates that there are two power supplies; both AC and DC are supplying power."
