Twisted Pair Ports - Allied Telesis AT-x230-10GP Installation Manual

Appendix : Overview

Twisted pair ports

18
The AT-x230-10GP, AT-x230-18GP and AT-x230-28GP Gigabit Ethernet
switches feature 8, 16 and 24 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 74.
Cables connecting to these ports have a maximum 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 1000 Mbps
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.
