Twisted pair ports
The AT-x230-10GP and AT-x230-18GP Gigabit Ethernet Switches feature
8 and 16 twisted pair ports, respectively. All ports are 10BASE-T,
100BASE-TX, and 1000BASE-T compliant. You can set the port speeds
and duplex modes either automatically with IEEE 802.3u Auto-Negotiation
or manually with the management software.
The twisted pair ports feature 8-pin RJ45 connectors. For the port pinouts,
see “Connectors and port pinouts” on page 69.
The ports have a maximum operating distance of 100 m (328 feet). For 10
Mbps operation, the ports require Category 3 or better 100 ohm shielded
or unshielded twisted pair cabling. For 100 or 1000Mbps operation, the
ports require Category 5 or Enhanced Category 5 (5E) 100 ohm shielded
or unshielded twisted pair cabling.
The ports feature auto-MDI, which automatically configures the ports as
MDI or MDIX. This feature allows you to use straight-through twisted pair
cables regardless of the wiring configurations of the ports on the end
nodes.
Note
A switch port connected to an end node that is not using Auto-
Negotiation should not use Auto-Negotiation to set the speed and
duplex mode, as a duplex mode mismatch may occur. In this case,
disable Auto-Negotiation and set the port’s speed and duplex mode
manually.
