Auto MDI/
MDI-X
The ports are auto-MDI/MDI-X. They automatically configure themselves
as either MDI or MDI-X. This feature allows you to use either straight-
through or crossover twisted pair cables to connect devices to the ports.
Note
Disabling Auto-Negotiation on a port also disables Auto MDI/MDI-X
on the port. You must set the MDI/MDI-X manually through the
management software, refer to the AT-S39 Management
Software User’s Guide.
