1. Summary
GA-AS48TPoE+ has 50 ports which are 10BASE-T/100BASE-TX/1000BASE-T compatible ports.
Ports 1 to 48 (twisted pair ports) support IEEE802.3at PoE power supply functions.
2. Feature
（1） Ports 1 to 50 (twisted pair ports) are 10BASE-T/100BASE-TX/1000BASE-T corresponding to auto-negotiation.
（2） The twisted pair ports 1 to 48 can supply power conforming with IEEE802.3at. They can supply a maximum of 30 W of power per port,
and the device total can supply a maximum of 336 W of power.
（3） All of the twisted pair ports are equipped with straight/cross cable automatic detection functions. Straight cables can be used to make
interconnections without distinctions between the terminals and network devices having to be made.
(The factory default is for ports 1 to 48 to have MDI-X be fixed.)
（4） If equipped with IEEE802.3az (LPI) compatible Energy Efficient Ethernet functions (hereinafter EEE), and if data is transmitted when
linked up, the energy efficient state will be moved to, whereas each port can suppress power consumption.
（5） Automatically detects the connection states via the equipped energy efficiency mode, and suppresses power consumption to required
levels.
（6） VLAN function allows free grouping of up to 256 VLANs.
（7） The IEEE802.1p compatible QoS function is supported.
（8） Has an Internet Mansion function, which ensures security between each door.
（9） The Switching Hub settings can be configured via a web browser. Since the IP address is not set when the Switching Hub is shipped
from the factory, it can be changed by connecting the computer and the Switching Hub which have the ZEQUO assist Plus that is on
the CD-ROM installed on them with the twisted pair cables.
