1. Summary
Switch-M8eGi is an all Giga bit Ethernet Switching Hub with management function having 8 ports of 10/100/1000BASE-T and SFP extension slot.
2. Feature
（1） Has wire speed layer 2 switching functions.
（2） Ports 1 to 8 are auto negotiation-ready 10/100/1000BASE-T ports. Their speed and communication mode can be changed
by configuration. Port 9 can be exclusively used as an SFP extension slot.
（3） 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 8 are set at MDI-X. (default))
（4） 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.
（5） Has a loop detection history function, which notifies when a loop occurs with the corresponding LED and enables a network
administrator to identify the looped port after the loop is removed.
（6） Fanless design solves noise problem or fan failure.
（7） Power consumption can be suppressed by switching off the port LEDs (left) via the ECO mode LED functions.
（8） The IEEE802.1p compatible QoS function is supported.
（9） Has an Internet Mansion function, which ensures security between each door.
（10） Has a port grouping function, which groups ports that are allowed to communicate with one another to limit communications
between different groups.
（11） 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. Factory default : Disable
（12） Embedded power saving mode detects the connection status automatically and saves power consumption to minimum.
Factory default : Disable
（13） VLAN function allows free grouping of up to 256 VLANs.
（14） IEEE802.1Q VLAN tagging is supported, and a maximum of 256 VLANs can be registered.
（15） The IEEE802.1X compatible user authentication function （EAP-MD5/TLS/PEAP） is supported.
（16） Each single port supports IEEE 802.1X, Web, and MAC authentication protocols, eliminating the need for individually
setting the ports’ authentication parameters.
（17） Supports ZEQUO assist Plus. Processes from introduction to maintenance can be performed easily.

（7）LOOP HISTORY（Loop History mode）LED
Green Light : Operating in Loop History mode. Green Blink : Loop is occurring,
or occurred within the last 3days.
You can display the following items using the LED display change button. Display for the connection with a connected terminal （Status mode）,Display for the 1000 Mbps transmission rate （GIGA mode） , Display for the 100Mbps or 10 Mbps transmission rate （Speed mode）, Display for the full-duplex or half-duplex transmission system （DUPLEX mode）, Display for ports with a loop history （Loop history mode） , All port LED lamps can be turned OFF （ECO mode）.
Display of each port is refer to table 1 of No.5.
The mode at the start is called “Base mode”. There are two types of Base modes : Status mode （factory default setting） and ECO mode. You can change the Base mode by holding down the LED display change button （for at least 3 sec）. When the Base mode is changed normally, all STATUS/ECO , GIGA , 100M , and FULL LED lamps light up at the same time. When you release the button, the Base mode is changed to the selected mode. If the mode is changed to the GIGA mode, Speed mode, DUPLEX mode, or Loop History mode and the LED display switch button is not used for one minute or longer, the mode automatically returns to a Base mode （Status mode or ECO mode）. The Base mode is maintained even after the power is turned OFF.
