AT-GS900/16, AT-GS900/24 Fanless Gigabit Ethernet Switches Installation Guide

Planning the Installation

Table 3 contains the cabling specifications for the twisted pair ports.

Note

The twisted pair ports on the switch feature Auto-MDI when

operating at either 10, 100, or 1000 Mbps. Each port is individually

configured as MDI or MDI-X when connected to an end-node.

Consequently, 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. For example, a port operating at 10 or 100

Mbps uses two pairs of twisted pair wiring while a port operating at

1000 Mbps uses four pairs of twisted pair wiring.
