AT-x230-10GP and AT-x230-18GP Switches Installation Guide

Cable specifications

Table 9 contains the cable specifications for the twisted pair ports.

Note

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

operating at 10, 100, or 1000 Mbps. A port is configured as MDI or

MDIX when it is connected to an end node. Consequently, you can

use a straight-through twisted pair cable when connecting any type

of network device to a port on the switch.
