AT-FS708/POE Fast Ethernet Switch Installation Guide

Planning the Installation

Table 6 contains the cabling specifications for the twisted pair ports.

Note

The twisted pair ports on the switch feature auto-MDI when
operating at 10 or 100 Mbps. Each port is individually configured as
MDI or MDI-X when connected to an end node. Therefore, you can
use either a straight-through or crossover twisted pair cable when
connecting any network device to a twisted pair port on the switch.
