Transmitting and receiving network system：
IEEE802.3
10BASE-T
IEEE802.3u
100BASE-TX
IEEE802.3ab
1000BASE-T
energy efficient Ethernet （*2）
：IEEE802.3az(LPI)
Transmission speed
：10/100/1000Mbps, full/half duplex
Compatible cable
：Twisted pair cable
（At least equivalent to EIA/TIA568 category 5e）
Maximum transmission distance
：100m
Auto-Negotiation
：Communication speed and full/half duplex are
automatically recognized.
The setting can be fixed to 10Mbps, 100Mbps,
or 1000Mbps and full duplex or half duplex.
Up to 30 W of power can be supplied to ports 1 to 24.
*1 Embedded power saving mode detects the connection status automatically
and saves power consumption to minimum.
*2 Equipped with energy efficient Ethernet (EEE) conforming to IEEE802.3az (LPI).
When there is no data transmission at link up, the energy-saving state
automatically starts so that power consumption can be reduced on each port.
