- IP178G: 68 Pin QFN, 0~70
IP178G is fabricated with advanced CMOS
(85nm) technology and only requires a 3.3V single
power supply. This feature makes IP178G used
very low power consume, such as the full load
operation (100Mbps full duplex 8 ports), it only
takes 0.95W.
IP178G also supports Power Management Tool
(PWMT®) for IEEE 802.3az, APS, WOL+ and PWD
for Green Power. While two link devices have no
IEEE 802.3az capability, IP178G use WOL+ to
change link from 100Mbps to 10Mbps for saving
power.
The PWD, force-off power saving of IP178G is
designed for power down switch immediately by
pushing a button, user don’t plug out the power
adapter. Push the button again, it will power on
immediately.
Except Low Power and Rich Power Saving
method, IP178G supports AFT® for saving
Customer Testing Cost. By using a push button and
cables, IP178G will Auto test completely by itself.

Port 0 received packet with reserved TCP/UDP port number, Port 0 will enable its
ingress port as a high priority port for 300 seconds.
If the other ports received packets with the same reserved port number, it also has the
same behavior as port 0.
