Auto PD Recovery

41.1  Auto PD Recovery Overview

Things can go wrong with any network devices. A PD (for example, IP camera) may slow down or freeze 
and need to be restarted if it is overworked or a bug causes a memory leak. When a connected PD 
ceases to respond, Automatic PD Recovery allows the Switch to restart the PD by turning it off and on 
without the need for on-site troubleshooting.

41.1.1  What You Can Do

Use the 

Auto PD Recovery

 screen (

Section 41.2 on page 358

) to enable and configure automatic PD 

recovery on the Switch.

41.2  Auto PD Recovery

This screen lets you turn on automatic PD recovery on the Switch and its Ethernet ports. You can 
configure whether the Switch uses LLDP or ping to check the current status of a connected PD.

The ping is sent through the Switch's default management IP address to the designated port. To ping the 
PD, the port must share the same VLAN as the Switch's management VLAN.

Figure 270   

Auto PD Recovery Application

The PD may stop responding to the Switch’s detection over ping or LLDP 

during firmware upgrade. Disable the Auto PD Recovery function to 

prevent damage to the PD caused by a power cutoff during firmware 

upgrade.
