AT-GS900/16, AT-GS900/24 Gigabit eco-friendly Ethernet Switch Installation Guide

Hardware Feature Description

The following sections describe hardware features of the AT-GS900/16

and AT-GS900/24 Fanless Gigabit Ethernet switches:

 System and Port LEDs

 Twisted Pair Ports

 AC Power Connector

Twisted Pair

Ports

The AT-GS900/16 Fanless Gigabit Ethernet switch features 16 twisted

pair ports, and the AT-GS900/24 Fanless Gigabit Ethernet switch features

24 twisted pair ports.

Type of Connector

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

pinouts, refer to “RJ-45 Twisted Pair Port Connectors” on page 44.)

Speed

Each port is 10/100/1000Base-T compliant and is capable of 10, 100, or

1000 Mbps speed, respectively. 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.

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.

Note

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 23.
