CHAPTER 28
Auto PD Recovery
28.1  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.
28.1.1  What You Can Do
Use the Auto PD Recovery screen (Section 28.2 on page 230) to enable and configure automatic PD 
recovery on the Switch.
28.2  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 167   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.
To open this screen, click Advanced Application > Auto PD Recovery.
