DGS-1100-05PD - Achiving 18W PoE Passthrough
« on: June 21, 2019, 12:06:53 AM »

The switch supports custom PoE Power Limit and 18W overall budget.

However, both ports can be enabled only when configured as Class 1 or Class 2 (per the data sheet).

Could the firmware be adjusted to enable both ports when combined configured limit is less than 18W? i.e. Class 2 on one port and custom for the remainder on the other.

In my case I have two devices reporting class 0 and the 18W is plenty, but one device needs 8W peak. So 7W and 11W would be a perfect configuration for me.

Quick update for the benefit of the search.

  • There is a bug in B031 that prevents more than one port being used if the power output mW is configured manually, fixed in B033
  • The switch can provide 18W on one port when manually configured to do so.
  • The switch reserves 15.4W for any port configured with more than 7W, therefore, only one port can be powered on if more than 7W is configured.

As always, D-Link support are super helpful, but it seems hardware limitation prevents the use of more than 14W when both ports are powered.
