1. Summary
Switch-M8eG is an all Giga bit Ethernet switching hub equipped with eight 10BASE-T/100BASE-TX/1000BASE-T ports
and one SFP extension slot with a management function.
2. Feature
（1） Fanless design solves noise problem or fan failure.
（2） Has a loop detection function, which notifies when a loop occurs with the corresponding port LED and automatically
shuts down the looped port.
In addition, when a port is shut down and when it automatically recovers, an SNMP trap can be sent to notify the administrator.
（3） 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.
（4） Embedded power saving mode detects the connection status automatically and saves power consumption to minimum.
（5） Use of LED indicator switching button saves power consumption of LED lamps.
（6） 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.
（7） 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 7 are set at MDI-X. (default))
（8） VLAN function allows free grouping of up to 256 VLANs.
（9） The IEEE802.1p compatible QoS function is supported.
（10） Has an Internet Mansion function, which ensures security between each door.
（11） Has a port grouping function, which groups ports that are allowed to communicate with one another to limit communications
between different groups.
（12） 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.
（13） The IEEE802.1X compatible user authentication function (EAP-MD5/TLS/PEAP) is supported.
（14） Supports ZEQUO assist Plus. Processes from introduction to maintenance can be performed easily.

Display of each port
is refer to table 1
of No.4 .
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).
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.
