 Ports 1 to 4 are 10/100/1000BASE-T ports corresponding to auto negotiation.
Also their speed and communication mode can be switched by configuration.
Ports 5 and 6 can be used as a 10/100/1000BASE-T port corresponding to auto
negotiation or an SFP extension slot exclusively.
 Ports 1 to 4 can supply power conforming with IEEE802.3at and 802.3af. Supplying
power up to 30 W per port, and up to 62 W in total is possible.

Is equipped with PoE auto reboot functions, and monitoring, and the switching of the
power supply OFF/ON to ports is possible via Ping, LLDP, and the 3 traffic volume methods.
 Fanless design solves noise problem or fan failure.
 All twisted pair ports support straight/cross cable auto sensing function. Simply
connect devices with straight cables, whether it is a terminal or a network device.
(This function does not work if the port communication configuration is set at Fixed
or Link Aggregation. Ports 1 to 4 are set at MDI-X. (default))

Telnet/SSH allows remote configuration changes and verifications of the Switching Hub.
Remotely configure the PoE settings for each port (Ports 1 to 4).

The connection status for each port is detected by the power saving mode, and it can suppress
the power consumption to required volumes when not linked up. (Factory default: deactivated)
 Rapid Spanning Tree Protocol is supported, allowing to build a system with redundancy.
 The IEEE802.1p compatible QoS function is supported.


MAC authentication, and WEB authentication via one port, and an authentication
network which is matched to the kinds of connection terminals can be constructed.
 Equipped with step authentication functions, and can prevent illegal access of the terminals.
 Since it is equipped with authentication supplicant functions, a more robust security
configuration can be configured in combination with the upper switch’s IEEE802.1X
authentication functions.
Due to the loop detection/shutoff function, a port where loop has occurred can be
automatically shut off to prevent loop failures. When a port is shut off and recovered
automatically, SNMP trap can be sent to notify the incident to the administrator.
Moreover, the port with a loop can be identified by loop notification on the LEDs on
the main unit and referring the history of loop on the setting screen.
The PoE scheduler function enables scheduling of PoE power supply control.
