Ports

The AT-8000/8POE Fast Ethernet Switch features eight twisted pair ports,

one 10/100/1000Base-T port, and one combo SFP port.

Twisted Pair

Ports

The twisted pair ports feature 8-pin RJ-45 connectors. (For the port

pinouts, refer to “Connectors and Port Pinouts” on page 55.)

The ports on the AT-8000/8POE Fast Ethernet Switch are 10Base-T and

100Base-TX compliant and are capable of 10 megabits per second

(Mbps) and 100 Mbps speeds.

The ports are IEEE 802.3u Auto-Negotiation compliant. With Auto-

Negotiation, 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 10 Mbps, the switch sets the

port connected to the end node to 10 Mbps.

Each twisted pair port on the switches can operate in either half- or full-

duplex mode. The twisted pair ports are IEEE 802.3u-compliant and Auto-

Negotiate the duplex mode setting.

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 27.

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) 100 ohm shielded

or unshielded twisted pair cabling is required.

The twisted pair ports are auto-MDI/MDIX. They automatically configure

themselves as either MDI or MDI-X. This feature allows you to use either

straight-through or crossover twisted pair cables to connect devices to the

ports.

The ports can operate as either standard 10/100Base-T ports or as PoE

ports.

10/100/1000

RJ-45 Uplink

Port

The 10/100/1000Base-T uplink port is a backup for the SFP uplink port. If

the SFP’s fiber connection fails, the 10/100/1000Base-T uplink port takes

over the connection.

SFP Port The SFP port, port 9, can operate in place of its twisted pair port

equivalent to provide fiber optic uplink connectivity. When an SFP is

inserted in the SFP port and a fiber optic cable is connected, the

corresponding twisted pair port is disabled.

RS-232 Console

Port

The RS-232 console port uses the management cable supplied with the

switch. Through the console port you can connect to the switch and use

the menus-based AT-S81 management software user interface.

LEDs

The LEDs on the front panel display the system and port status

information. Each port has two LEDs as shown in Figure 3.
