100Base-FX Fiber Optic Ports

The AT-8016F/MT, AT-8016F/SC, and AT-8016F/ST switches feature 16 fiber optic ports. The AT-8026FC switch have two fiber optic ports. The AT-8088/MT and AT-8088/SC switches have eight fiber optic ports. The operating characteristics of the fiber optic ports on all the switches are the same.

AT-8000 Series Fast Ethernet Switches Installation Guide

Type of

Connector

The fiber optic ports on the AT-8016F/SC, AT-8026FC, and AT-8088/SC switches feature SC connectors.

The fiber optic ports on the AT-8016F/ST switch features ST connectors.

The fiber optic ports on the AT-8016F/MT and AT-8088/MT switches feature MT-RJ connectors.

Speed The fiber optic ports have a fixed operating speed of 100 megabits per

second (Mbps). The speed cannot be changed.

Duplex Mode The fiber optic ports can operate in either half- or full-duplex mode. You

can set the duplex mode manually or allow the switch to set it automatically through Auto-Negotiation.

Maximum

Distance

Each fiber optic port has a maximum operating distance of 2 kilometers (1.25 miles) when operating in full-duplex mode and 412 meters (1,360 feet) when operating in half-duplex mode.

Type of Cable The fiber optic ports can use either 50/125 or 62.5/125 micron

multimode fiber optic cable.

Note

Do not use single-mode fiber optic cable with these ports.

Overview

10/100Base-TX Twisted Pair Ports

The twisted pair ports featured on the AT-8000 Series Switch are described below.

Type of

Connector

All twisted pair ports feature 8-pin RJ-45 connectors. For the port pinouts, refer to ”RJ-45 Twisted Pair Port Pinouts” on page 85.

Speed The twisted pair ports are 10/100Base-TX compliant and are capable of

both 10 megabits per second (Mbps) and 100 Mbps speeds. You can set the port speed manually or, since the ports are IEEE 802.3u AutoNegotiation compliant, you can let the switch set each port’s speed automatically. 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.

Note

Auto-Negotiation is activated as the default on all twisted pair ports on the switch. To deactivate Auto-Negotiation and set the speeds manually, refer to the AT-S39 Management Software User’s Guide.

Duplex Mode Each twisted pair port on the switch can operate in either half- or full-

duplex mode. The twisted pair ports are IEEE 802.3u-compliant and will Auto-Negotiate the duplex mode setting.

Maximum

Distance

If desired, Auto-Negotiation on one or all of the switch ports can be disabled so that you can set the duplex mode manually through the switch’s management software.

Note

In order for a switch port to successfully Auto-Negotiate its duplex mode with an end-node, the end-node should also be using AutoNegotiation. Otherwise, a duplex mode mismatch can occur. A switch port, using Auto-Negotiation, will default to half-duplex if it detects that the end-node is not using Auto-Negotiation. This will result in a mismatch if the end-node is operating at a fixed duplex mode of full-duplex. Consequently, when connecting an end-node with a fixed duplex mode of full-duplex to a switch port, you should use the AT-S39 management software to disable Auto-Negotiation on the port and set the port speed and duplex mode manually.

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

24

AT-8000 Series Fast Ethernet Switches Installation Guide

Type of Cabling For 10 Mbps operation, Category 3 or better 100 ohm shielded or

unshielded twisted pair cabling is required. For 100 Mbps operation, Category 5 or Enhanced Category 5 (5E) 100 ohm shielded or unshielded twisted pair cabling is required.

Auto MDI/

MDI-X

The twisted pair ports are auto-MDI/MDI-X. They automatically configure themselves as either MDI or MDI-X. This feature allows you to use a straight-through twisted pair cable to connect any type of network device to a switch port.

Note

Disabling Auto-Negotiation on a port also disables Auto MDI/MDI-X on the port. You must set the MDI/MDI-X manually through the management software, refer to the AT-S39 Management Software User’s Guide.

Port Pinouts Refer to Table 9 on page 85 and Table 10 on page 85 for the port

pinouts.

Overview

10/100/1000Base-T Twisted Pair Ports

The two twisted pair 10/100/1000Base-T ports featured on the AT-8026T are described below.

Type of

Connector

The ports have 8-pin RJ-45 connectors. The ports use four pins when operating at 10 or 100 Mbps and all eight pins when operating at 1000 Mbps.

Speed The ports can operate at 10, 100, or 1000 Mbps. The speed is set

automatically through Auto-Negotiation or you can set the speed manually through the management software.

Duplex Mode The ports can operate in either half- or full-duplex mode. The ports are

IEEE 802.3u compliant and will Auto-Negotiate the duplex mode. If needed, Auto-Negotiation can be disabled so that you can set the duplex mode manually through the management software.

Note

In order for a switch port to successfully Auto-Negotiate its duplex mode with an end-node, the end-node should also be using AutoNegotiation. Otherwise, a duplex mode mismatch can occur. A switch port, using Auto-Negotiation, will default to half-duplex if it detects that the end-node is not using Auto-Negotiation. This will result in a mismatch if the end-node is operating at a fixed duplex mode of full-duplex. Consequently, when connecting an end-node with a fixed duplex mode of full-duplex to a switch port, you should use the AT-S39 management software to disable Auto-Negotiation on the port and set the port speed and duplex mode manually.

Maximum

The ports have a maximum operating distance of 100 meters (328 feet).

Distance

Type of Cable For 10 Mbps, the port requires 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.

Auto MDI/

MDI-X

The ports are auto-MDI/MDI-X. They automatically configure themselves as either MDI or MDI-X. This feature allows you to use a straight-through twisted pair cable to connect any type of network device to a switch port.

Note

Disabling Auto-Negotiation on a port also disables Auto MDI/MDI-X on the port. You must set the MDI/MDI-X manually through the management software, refer to the AT-S39 Management Software User’s Guide.

Port Pinouts For the pinouts of these ports when operating at 10 or 100 Mbps in the

MDI configuration, refer to Table 9 on page 85. For the pinouts of the ports when operating at 10 or 100 Mbps in the MDI-X configuration, refer to Table 10 on page 85. For port pinouts when the ports are operating at 1000 Mbps, refer to Table 11 on page 86.

Overview

Gigabit Interface Converter (GBIC) Expansion Slots

The AT-8024GB Fast Ethernet Switch has two expansion slots on the front panel, labelled Port A and Port B, which correspond to Ports 25 and 26, respectfully. Each slot can accommodate one optional fiber optic Gigabit Interface Converter (GBIC) Ethernet module.

An GBIC module is a fast and easy way for you to add an 1000 Mbps fiber optic port to your Fast Ethernet switch. GBIC modules can be used to extend the distance of your network, build a high-speed backbone network between switches, or connect additional end-nodes to the network, such as high-speed servers.

Figure 12 shows an example of a fiber optic GBIC module.

Module Expansion Slots

The AT-8016/xx, AT-8024M, and AT-8088/xx switches have two expansion slots. The AT-8012M and AT-8012M-QS have one expansion slot. Each slot can accommodate an expansion module. You can use the slots to add 100Base and 1000Base fiber optic and twisted pair ports to the switch.

Overview

Twisted Pair Port LEDs and the LED Mode Select Button

The twisted pair port LEDs and the LED Mode Select button for the AT-8000 Series Switches are describe below.

The port LEDs on the front panel display port status information. Each port has two LEDs. The Link LED indicates whether there is a valid link between a port and the end-node connected to it.

Each port also has a Mode LED. This LED displays a variety of status information, including port speed and duplex mode. You use the Mode Select button on the front panel to toggle the Mode LEDs to display different status information. The LEDs next to the Mode Select button indicate the status being displayed by the port Mode LEDs. For example, if the Mode 100 LED is green, then the port Mode LEDs are displaying port speed.

Note

Toggling the Mode Selection button does not affect the normal operations of the switch.

Table 2 describes the twisted pair port LEDs of the AT-8000 Series Switches, except for the AT-8088/xx switch, which does not have a LED Mode Select button.
