1. Summary
GA-ML24TCPoE+ is an Ethernet Switching Hub with management function having 28ports of 10/100/1000BASE-T
and SFP extension slot, one of which is selectable.
Ports 1 to 24 support IEEE802.3at/af PoE power supply function.
2. Feature
（1） 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 to 28 can be used as a 10/100/1000BASE-T port corresponding to auto negotiation or an SFP extension slot exclusively.
（2） Ports 1 to 24 can supply power conforming with IEEE802.3at and 802.3af. Supplying power up to 30 W per port,
and up to 185 W in total is possible.
（3） Is equipped with PoE auto reboot function, and monitoring, and the switching of the power supply OFF/ON to ports is possible
via Ping, LLDP, and the 3 traffic volume methods.
（4）Is equipped with silent fan control functions, can be set to match the operating environment temperature and power supply,
and be used with any of the fan rpm, “High”, “Low” and “Min”.
（5） 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 24 are set at MDI-X. (default))
（6） Telnet/SSH allows remote configuration changes and verifications of the Switching Hub.
Remotely configure the PoE settings for each port (Ports 1 to 24).
（7） 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)
（8） Rapid Spanning Tree Protocol is supported, allowing to build a system with redundancy.
（9） The IEEE802.1p compatible QoS function is supported.
（10） Supports triple authentication that can simultaneously wait on IEEE802.1X authentication, MAC authentication, and
WEB authentication via one port, and an authentication network which is matched to the kinds of connection terminals can be
constructed.
（11） Equipped with step authentication functions, and can prevent illegal access of the terminals.
（12） 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 function.
（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.
（15） Supports ZEQUO assist Plus. Processes from introduction to maintenance can be performed easily.

5－4. LED display
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 full-duplex or halfduplex 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 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, 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.
LED display change button
Switch two types of Base mode s and their LEDs in the following way:
When Base mode is Status mode （factory default setting）
Press “LED DISPLAY CHANGE BUTTON” manually.
