AT-GS900/8POE Gigabit 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. A
port operating at 10 or 100 Mbps uses four of the eight strands in
twisted pair wiring. A port operating at 1000 Mbps uses all eight
strands.
