Information:
The firmware version 2.52a for the switch LANCOM GS-2326P (download) rectifies the incorrect behavior occasionally seen during powered device detection. For cable lengths exceeding 35m, powered devices were not always detected and the power supply was enabled.
To resolve this problem, a new default setting named 2-Point-Legacy was added to the Detection configuration of the switch. This setting is automatically loaded with the factory settings.
If you upload firmware update V2.52a to a previously configured switch with the setting for powered device detection set to a value other than the default, your setting will remain unchanged.
In this case, if you experience problems with the powered device detection, the value must be manually set to 2-Point-Legacy.

Default setting before the firmware update to version 2.52a:



Default setting after the firmware update to version 2.52a:
