Overview

Gigabit Ethernet Ports

Twisted Pair Ports

The AT-9000/28 Gigabit Ethernet ecoSwitch features 24 twisted pair 10/ 100/1000Base-T ports, and four combo SFP/copper ports.

The twisted pair ports feature 8-pin RJ-45 connectors. (For the port pinouts, refer to “10/100/1000Base-T Twisted Pair Port Connectors” on page 48.)

The ports on the AT-9000/28 Gigabit Ethernet ecoSwitch are 1000Base-T, 100Base-TX and 10Base-T compliant and are capable of 1000 megabits per second (Mbps), 100 Mbps and 10 Mbps speeds.

The ports are IEEE 802.3u Auto-Negotiation compliant. With Auto- Negotiation enabled, the switch automatically matches the highest possible common speed between each switch port and each end node. For example, if an end node is capable of only 1000 Mbps, the switch sets the port connected to the end node to 1000 Mbps.

The default setting for the twisted pair ports is Auto-Negotiate, which automatically determines the duplex mode setting. Each twisted pair port on the switches is capable of operating in either half- or full-duplex mode.

Note

In order for the switch to set the duplex mode for each port correctly, the end nodes that you connect to the switch ports should also use Auto-Negotiation. Otherwise, a duplex mode mismatch can occur, affecting network performance. For further information, refer to “Duplex Mode” on page 21.

Each twisted pair port has a maximum operating distance of 100 m (328 feet).

For 10 Mbps operation, Category 3 or better 100 ohm shielded or unshielded twisted pair cabling is required. For 100 or 1000 Mbps operation, Category 5 and Enhanced Category 5 (5E) or better 100 ohm shielded or unshielded twisted pair cabling is required. For cable specifications, go to “Twisted Pair and Fiber Optic Cable Specifications” on page 29
