PD Alive Check

Configure PD Alive Check

PoE > PD Alive

PD Alive Check is used to check the connection between the switch and the device

connected to it. The switch sends a ping, and if the device does not respond, the switch

will try to revive the device by doing a power cycle of the connected device.

1. Log into your switch management page (see “Access your switch management page”

on page 5).

2. Click on PoE and click on Time Range.

3. Review the settings for each port. Next to each port entry, click Apply to save the

settings.

• State: Select Enabled to enable PD Alive check and Disabled to disable it

• Port: Indicates the port with a specific PoE status and that you are configuring.

• PD Alive State: Select Enabled to enable PD Alive Check for the selected port

and Disabled to disable it

• PD IP Address: Enter the IP address of the device that is connected to the port

• Poll Interval: Enter the desired time for how often the switch will send a ping

to the connected device

• Retry: Enter the amount of times the switch will try to send a ping before

power cycling

• Power Off Time: Enter the desired time for the switch to turn off the power

before sending power again

• Start Up Time: Enter the time it takes for your PD device to boot up. If the

entered time is too short, the switch will keep powering on and off the device.

• Action setting: Select Reset to power cycle the device, Notify to send a

notification, or Both to reset and notify.

4. At the bottom of the left hand panel, click Save.

5. Select the Config you would like to save the settings to, then click Save Settings to

Flash.

Note: This step saves all configuration changes to the NV-RAM to ensure that if the

switch is rebooted or power cycled, the configuration changes will still be applied.
