Where to Go First

AT-9400 Series Gigabit Ethernet Switches Installation Guide
Allied Telesis recommends that you read Chapter 1, Overview, in the AT-S63 Management Software Features Guide before you begin to manage the switch for the first time. There you will find a variety of basic information about the unit and the management software, like the two levels of manager access levels and the different types of management sessions.
The AT-S63 Management Software Features Guide is also your resource for background information on the features of the switch. You can refer there for the relevant concepts and guidelines when you configure a feature for the first time.

Chapter 1

Overview

The AT-9400 Switches are managed Gigabit Ethernet switches for Ethernet, Fast Ethernet, and Gigabit Ethernet networks. The AT-9400 Switches are divided into two groups:
Layer 2+ Switches
– AT-9408LC/SP
– AT-9424T/GB
– AT-9424T/SP
Basic Layer 3 Switches
– AT-9424T
– AT-9424T/POE
– AT-9424Ts
– AT-9424Ts/XP
– AT-9448T/SP
– AT-9448Ts/XP
The differences between the two groups are explained in the AT-S63 Management Software Features Guide.

10/100/1000Base-T Twisted Pair Ports

This section describes the twisted pair ports on the switches. (This section does not apply to the AT-9408LC/SP Switch.)

Connector Type The ports are 8-pin RJ-45 connectors that use four pins at 10 or 100 Mbps

and all eight pins at 1000 Mbps. For the pin assignments, refer to “RJ-45 Twisted Pair Port Pinouts” on page 80.

Speed A port’s speed can be 10, 100, or 1000 Mbps. The speed can be set

automatically through Auto-Negotiation, the default setting, or manually with the AT-S63 Management Software.
To operate at 1000 Mbps, a twisted pair port must be set to Auto ­Negotiation. The speed of a twisted pair port cannot be manually set to 1000 Mbps.

Duplex Mode A twisted pair port can operate in either half- or full-duplex mode. (Full-

duplex mode is the only mode available when a port is operating at 1000 Mbps.) The twisted pair ports are IEEE 802.3u-compliant and Auto­Negotiate the duplex mode setting.
You can disable Auto-Negotiation on one or all of the switch ports so that you can set the duplex mode manually through the AT-S63 Management Software.
In order for a switch port to successfully Auto-Negotiate its duplex mode with a 10 or 100 Mbps end node, the end node should also be configured for Auto-Negotiation. Otherwise, a duplex mode mismatch can occur. A switch port using Auto-Negotiation defaults to half-duplex if it detects that the end node is not using Auto­Negotiation. This results in a mismatch if the end node is operating at a fixed duplex mode of full-duplex.
To avoid this problem when connecting an end node with a fixed duplex mode of full-duplex to a switch port, use the AT-S63 Management Software to disable Auto-Negotiation on the port and set the port speed and duplex mode manually.
