Hello, everyone!
Today, I would like to share the configuration of the PoE power supply for the EHT port of the EA5821.
Product Model
EA5821
Problem Description
The AP connected to the EA5821 is powered off. The AP is powered by the EA5821 through PoE.
Problem Analysis
APs are connected to PON devices to provide wireless network services for users. The EA5821 provides power to APs in PoE mode.
Each ETH port provides 15W power by default. Sometimes, the power of the AP is greater than 15W, causing the AP to be powered off.
Root Cause
The max PoE power of the port is not configured.
Solution Description
It is recommended that you set the maximum power of the ETH port PoE to 30W during the deployment of the EA5821.
The configuration method is as follows:
To configure the power supply management of are PDs device to auto mode.
huawei(config)#interface eth 0/1
huawei(config-if-eth-0/1)#poe 1 enable mode signal priority critical max-power 30000 force-power enable
huawei(config-if-eth-0/1)#poe 2 enable mode signal priority critical max-power 30000 force-power enable
huawei(config-if-eth-0/1)#poe 3 enable mode signal priority critical max-power 30000 force-power enable
huawei(config-if-eth-0/1)#poe 4 enable mode signal priority critical max-power 30000 force-power enable
huawei(config-if-eth-0/1)#poe 5 enable mode signal priority critical max-power 30000 force-power enable
huawei(config-if-eth-0/1)#poe 6 enable mode signal priority critical max-power 30000 force-power enable
huawei(config-if-eth-0/1)#poe 7 enable mode signal priority critical max-power 30000 force-power enable
huawei(config-if-eth-0/1)#poe 8 enable mode signal priority critical max-power 30000 force-power enable
huawei(config-if-eth-0/1)#poe legacy
The PoE legacy command is used to enable the compatibility detection function of a PD device. When you need to detect the compatibility of the connected PD device based on the 150 nF detection standard in a protocol, run this command.
Thank you.
