3.2 Network interface specifications
3.2.1 Ethernet 10/100BASE-TX
(1) Mode setting on the port
Any of the modes below can be specified for Ethernet 10/100BASE-TX ports. The factory
default setting is auto-negotiation.
 Auto negotiation (default)
 100BASE-TX full duplex (fixed)
 100BASE-TX half duplex (fixed)
 10BASE-T full duplex (fixed)
 10BASE-T half duplex (fixed)
The following modes are applicable under auto-negotiation on the 10/100BASE-TX
port:
 100BASE-TX full duplex
 100BASE-TX half duplex
 10BASE-T full duplex
 10BASE-T half duplex
(2) Flow control functionality
This function is enabled when the connection is fixed to full duplex.
(3) Auto MDI/MDI-X functionality
This function is enabled when auto negotiation is specified.
In the fixed settings, MDI-X is always selected.
(4) PoE system
For the power supply pin configuration of the AC power supply (PoE) models, the
Alternative A method defined in standards IEEE 802.3af and IEEE 802.3at is used. The
power supply to equipment (powered devices) conforming to IEEE 802.3af and IEEE
802.3at standards is supported.
For power supply pin assignments on the Switch, see
Table 3-2 Power supply pin
assignment.
