8.8.1 PoE Time Range Status

Use this screen to see whether PoE is scheduled to be enabled on a port.
Click the PoE Time Range Status link in the Basic Setting > PoE Setup screen. The following screen opens.

DESCRIPTION
This field displays the power management mode used by the Switch, whether it is in
Classification or Consumption mode.
This field displays the total power the Switch can provide to the connected PoE-enabled
devices on the PoE ports.
This field displays the amount of power in percentage the Switch is currently supplying to the
connected PoE-enabled devices.
This field displays the amount of power the Switch is currently supplying to the connected PoE-
enabled devices.
This field displays the total amount of power the Switch has reserved for PoE after negotiating
with the connected PoE device(s).
Consuming Power (W) can be less than or equal but not more than the Allocated Power (W).
This field displays the amount of power the Switch can still provide for PoE.
Note: The Switch must have at least 16 W of remaining power in order to supply
power to a PoE device, even if the PoE device needs less than 16W.
This is the port index number.
This field shows which ports can receive power from the Switch. You can set this in
on page 87.
• Disable - The PD connected to this port cannot get power supply.
• Enable - The PD connected to this port can receive power.
This shows the power classification of the PD.
This is a number from 0 to 4, where each value represents a range of power (W) and power
current (mA) that the PD requires to function. The ranges are as follows.
• Class 0 - Default, 0.44 to 12.94
• Class 1 - Optional, 0.44 to 3.84
• Class 2 - Optional, 3.84 to 6.49
• Class 3 - Optional, 6.49 to 12.95
• Class 4 - Reserved (PSEs classify as Class 0) in a Switch that supports IEEE 802.3af only.
Optional, 12.95 to 25.50 in a Switch that supports IEEE 802.3at.
When the total power requested by the PDs exceeds the total PoE power budget on the Switch,
you can set the PD priority to allow the Switch to provide power to ports with higher priority first.
• Critical has the highest priority.
• High has the Switch assign power to the port after all critical priority ports are served.
• Low has the Switch assign power to the port after all critical and high priority ports are
served.
This field displays the PoE standard the Switch uses to provide power on this port.
This field displays the current amount of power consumed by the PD from the Switch on this port.
This field displays the maximum amount of power the PD could use from the Switch on this port.
