1. Summary
Switch-M2 is an Ethernet Switching Hub with management function having 24 ports of 10/100/1000BASE-T
and two pairs of 10/100/1000BASE-T port and SFP extension slot, one of which is selectable.
Port 1 to 24 support IEEE802.3at PoE power supply function.
2. Features
(1) Has wire-speed Layer 2 switching function.
(2) Ports 1 to 24 are 10/100/1000BASE-T ports corresponding to auto negotiation.
Also their speed and communication mode can be switched by configuration.
Ports 25 and 26 can be used as a 10/100/1000BASE-T port corresponding to auto negotiation or an SFP extension slot exclusively.
(3) Ports 1 to 24 can supply power conforming with IEEE802.3at. Supplying power up to 30 W per port, and up to 185 W in total is
possible.
(4) 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 16 are set at
MDI-X. (default))
(5) Telnet allows remote configuration changes and verifications of the Switching Hub. Remotely configure the PoE settings for each port
(Ports 1 to 24).
(6) 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.
(7) Embedded power saving mode detects the connection status automatically and saves power consumption to minimum.
(8) VLAN function allows free grouping of up to 256 VLANs.
(9) The IEEE802.1w Rapid Spanning Tree Protocol is supported, allowing to build a system with redundancy.
(10) The IEEE802.1p compatible QoS function is supported.
(11) The IEEE802.1X compatible user authentication function (EAP-MD5/TLS/PEAP) is supported.
(12) Has an Internet Mansion function, which ensures security between each door.
(13) 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.
(14) The PoE scheduler function enables scheduling of PoE power supply control.
