1. Product Outline
GA-/GA-A/GA-A/GA-AS4T/GA-AS10T/GA-AS12T
are Ethernet Switching Hubs that feature the Web control function and 10/100/
1000BASE-T ports.
The downlink ports support the PoE power supply function for IEEE802.3at/af
compatible devices.
1.1.
Features
・ All ports (twisted pair ports) are 10/100/1000BASE-T ports that support auto-
negotiation.
Speed and communication mode can be switched by configuring the settings.
・ The downlink ports of PoE supported models can provide PoE power supply to
IEEE802.3at and IEEE802.3af compatible devices.
A single port can supply power by PoE up to 30 W.
The total number of ports, number of downlink ports, and amount of power
supply by the whole unit are shown below for each model.
・ All twisted pair ports support the straight/cross cable auto sensing function.
You can simply connect devices with a straight cable, whether the target is a ter
-
minal or a network device.
(By factory default, downlink ports are fixed to MDI-X.)
・ The IEEE802.3az (LPI) compatible Energy Efficient Ethernet (EEE) function is sup
-
ported, allowing reduction of power consumption of each port by automatically
switching to a power saving state when there is no data communication at link
up.
・ The power saving mode detects the connection status automatically, and
reduces power consumption to a minimum.
・ The IEEE802.1Q compatible tag VLAN is supported, allowing registration of up
to 256 VLANs.
・ The Internet Mansion function is supported, allowing to ensure security of each
room in a building.
・ The IEEE802.1p compatible QoS function is supported.
・ The IEEE802.3ad compatible link aggregation function is supported, allowing
aggregation up to 8 ports.
(For GA- and GA-AS4T, up to 6 ports.)
