Power Supply

PoE

he PoE Management screen contains system PoE information for monitoring the current power usage and assigns the total amount of power the switch can provide to all its PoE ports.

Power Budget

Total Power Budget: Enter the amount of power the switch can provide to all ports.

Consumed Power: Displays the total amount of power (in watts) currently being delivered to all PoE ports.

PoE Port Settings

Items

Descriptions

Port

Displays the specific port for which PoE parameters are defined. PoE parameters are assigned to the powered device that is connected to the selected port.

State

Displays the active participating members of the trunk group. Enable: Enables the Device Discovery protocol and provides power to the device using the PoE module. The Device Discovery protocol lets the device discover powered devices attached to device interfaces and learn their classification.

Disable: Disables the Device Discovery protocol and halts the power supply delivering power to the device using the PoE module.

Priority

Select the port priority if the power supply is low. The field default is low. For example, if the power supply is running at 99% usage, and port 1 is prioritized as high, but port 6 is prioritized as low, port 1 is prioritized to receive power and port 6 may be denied power.

Low: Sets the PoE priority level as low.

Medium: Sets the PoE priority level as medium.

High: Sets the PoE priority level as high.

Critical: Sets the PoE priority level as critical.

Power Limit Type

Shows the classification of the powered device. The class defines the maximum power that can be provided to the powered device.

User Power Limit (W)

Select this option to set the power limit on the value configured in the User Power Limit field. Set the maximum amount of power that can be delivered by a port.

Note: The User Power Limit can only be implemented when the Class value is set to User-Defined.

Status

Shows the port's PoE status. The possible field values are:

Delivering Power: The device is enabled to deliver power via the port.

Disabled: The device is disabled from delivering power via the port.

Test Fail: The powered device test has failed. For example, a port could not be enabled and cannot be used to deliver power to the powered device.

Testing: The powered device is being tested. For example, a powered device is tested to confirm it is receiving power from the power supply.

Searching: The device is currently searching for a powered device. Searching is the default PoE operational status.

Fault: The device has detected a fault on the powered device when the port is forced on. For example, the power supply voltage is out of range, a short occurs, there is a communication error with PoE devices, or an unknown error occurs.

Class

The possible field values are:

Class 0: The maximum power level at the Power Sourcing Equipment is 15.4 Watts.

Class 1: The maximum power level at the Power Sourcing Equipment is 4.0 Watts.

Class 2: The maximum power level at the Power Sourcing Equipment is 7.0 Watts.

Class 3: The maximum power level at the Power Sourcing Equipment is 15.4 Watts.

Class 4: The maximum power level at the Power Sourcing Equipment is 30 Watts.

Output Voltage (V)

Shows the output voltage in Volts.

Output Current (mA)

Shows the output current in mA.

Output Power (W)

Shows the output power in W.

Select the port and click Edit button to revise settings; users may also click the Reset button to discard them.

PD Lifeguard

This feature is critical to provide reliable, high-quality video streaming at long distances, to enable real-time monitoring and recovery of surveillance if the camera goes down, and to keep the power supply uninterrupted during switch firmware upgrades.

Global Settings

Select "Enable" to turn on this feature.

Descriptions

Port

Displays the port number.

State

Indicates whether enabled or disabled.

Mode

Displays the corresponding mode:

Force Ping – Use Pinging method .

Auto – LLDP & Ping (default)

Specified IP

Displays the specified IP for Ping (when using Auto)

Ping Interval

Displays the Ping Interval (10 secs by default)

Ping Max Count

Displays the Ping max count (default 3 times; after 3 times of ping and failed, the corresponding port will be rebooted.)

Action Type

Displays the corresponding action type (Reboot with Syslog to reboot and send syslog, or just send syslog)

Power Recovery Interval

Displays the interval time to provide PoE power again to PD device after switch cuts off the power (in secs)

Reboot Max Retry Count

Displays the max number of reboot where users can manually check the PD device status after they received the “reboot max retry count” from syslog notification.

Reboot Count

Displays the read only value and will be used for “reboot max retry count” function. Users can monitor the reboot count's value in this item or use “Refresh” function in drop down list to refresh the reboot count number to 0.

PD Boot up Time

Displays the duration since the device's boot up while the switch will not be able to detect the device.

LLDP Expiry Pending Time

Displays the corresponding LLDP expiry pending time.
