Note: If you install a switching hub that does not have an automatic function to distinguish straight/
cross (MDI/MDI-X) connections, you will need to select a proper cable:
• Use a straight connection cable for an MDI to MDI-X connection.
• Use a cross connection cable for an MDI to MDI or MDI-X to MDI-X connection.
Generally, it is advisable to use an auto MDI/MDI-X switching hub.
