Reserved Power determined by: Radio button to select one of two modes for configuring how the
ports/PDs may reserve power:
Class: The PD will negotiate PD class then feed power if the PD request power is comply with
standard. If Maximum Power at the port is configured different then factory default value 30W,
the PD connects the port again; the PD cannot draw more power than the new configured
Maximum Power for the port. Class mode is the factory default mode. Note: Starting at FW
v1.01.1195, when the Maximum Power per port value is changed, it will change the mode to
Allocation mode. When Class mode is set, PoE allocated value will display after PoE negotiation.
Allocation: The switch will only examine power in the Maximum Power field. So once the switch
receives PD request power, the switch will check Maximum Power configuration, and if the
configured value is smaller than PD request power, the switch will not feed power.
Capacitor Detection: Check to enable or uncheck to disable the capacitor configuration. The default is
disabled. Check to enable legacy IP phones support.
PoE Port Configuration
Port: This is the logical port number for this row.
PoE Mode: The PoE Mode represents the PoE operating mode for the port (Enabled,
Disabled, or Force), where:
Disabled: PoE disabled for the port (default).
Enabled: Enables PoE IEEE 802.3at (Class 4 PDs limited to 30W) (default).
Force: The switch port will power up the linked PD without any detect/negotiate
mechanism (PD limited to 30W). Note: Only connect PDs which support a power
input of 48~56V to prevent damage to PDs. When the port changes to Force mode, the port’s PoE
LED will light immediately. Select Force mode for devices that do not do POE negotiation (e.g., for
a PoE DSRC RSU).
PoE Schedule: Disable PoE Scheduling or select a PoE Schedule profile for each port.
Priority: The Priority represents the ports priority. The three levels of power priority are
Low, High and Critical. The priority is used in the case where the remote devices require
more power than the power supply can deliver. In this case the port with the lowest
priority will be turned off first starting from the port with the highest port number.
Maximum Power [W]: Indicates the maximum power in watts that can be delivered to a
remote device. The valid range is 1-30 Watts. The default is 30 Watts.

Messages
Message: PoE Mode(Force): The switch port will power up the linked PD without any detect/negotiate
mechanism(PD limited to 30W). Do you want to change this setting?
Meaning: Confirmation message ensuring that you want to make this config change.
Action: Click the OK button only if you are sure you want to change this setting. See the “PoE Mode”
parameter description above. If you are not sure you want to change this setting, click the Cancel
button. Added at FW v 1.01.1209.
