13.4 Description of Fastethernet [AX1250S] [AX1240S]

A Fastethernet port uses a 10BASE-T or 100BASE-TX twisted pair cable (UTP). This
section describes a 10BASE-T or 100BASE-TX interface.

13.4.1 Functionality

(1) Connection interface: 10BASE-T or 100BASE-TX
(a) Automatic 10BASE-T/100BASE-TX recognition (auto-negotiation)
10BASE-T and 100BASE-TX support connection methods that use automatic recognition
(auto-negotiation) and fixed settings.

Automatic recognition: 10BASE-T and 100BASE-TX

Connection using fixed settings:10BASE-T and 100BASE-TX
You can configure either of the modes shown below. Select the appropriate mode for the
network to be connected. The default for the Switch is auto-negotiation mode.

Auto-negotiation

100BASE-TX full duplex (fixed)

100BASE-TX half duplex (fixed)

10BASE-T full duplex (fixed)

10BASE-T half duplex (fixed)
(b) Connection specifications of 10BASE-T and 100BASE-TX
The table below describes the connection specifications for transmission speed and duplex
mode (full or half) for a connection between the Switch and a remote device.
Note that, depending on the remote device, auto-negotiation is sometimes unavailable for a
10BASE-T or 100BASE-TX connection. For this reason, if at all possible, use the fixed
settings appropriate for the interface on the remote device.
