If you are using a GS2210-8HP or a similar switch and only a few ports provide PoE, or your connected PoE-devices will not start as expected please try these steps:
1. Log in to the unit by using its local IP address and credentials
2. Navigate to the Basic Setting > PoE Setup-menu
3. The PoE-Mode is set to classification by default. Change this to Consumption Mode and apply/save this configuration.
4. Reboot the system
