Hi,

Please check if SpanningTree is enabled by default on the switch,

this is possible for a 5324. If it is enabled, you might need to enable

'fastport' ( or also called SpanningTree EdgePort) on the normal end-user ports.

 

If you do use EdgePort:

    the port becomes immediately active and network traffic like DHCP will be handled correctly.

 

If you do use SpanningTree without Edgeport:

   the PC might respond to fast to the switch without being connected already.
