Description:
If a GS-23xx-/GS-3xxx or GS-45xx switch with active PoE detects external voltage on a PoE port, PoE is deactivated globally. This issue can occur if another switch with active PoE is connected to the switch, which supplies voltage on the port to the GS-23xx-/GS-3xxx or GS-45xx switch. To prevent this issue, PoE has to be deactivated on the additional switch for the port to the GS-23xx-/GS-3xxx or GS-45xx switch.
This article describes how PoE can be deactivated on a specific port on a LANCOM switch, so that PoE remains active on the GS-23xx-/GS-3xxx or GS-45xx switch.
Requirements:
- LCOS SX as of version
- 3.32 Rel for GS-23xx (download latest version)
- 4.00 Rel for GS-3xxx (download latest version)
- 5.20 Rel for GS-45xx (download latest version)
- Any web browser for accessing the webinterface
If you are using a switch from another manufacturer, please consult the manual or contact the manufacturer.
Procedure:
