LED Indicator:

Comprehensive LED indicators display the status of the Switch and the network (see the LED Indicators chapter below).

Fast Ethernet Ports (Port 1~48):

These ports support network speeds of either 10Mbps or 100Mbps, and can operate in half- and full- duplex transfer modes. These ports also supports automatic MDI/MDIX crossover detection function gives true “plug and play” capability, just need to plug-in the network cable to the hub directly and don’t care if the end node is NIC (Network Interface Card) or switch and hub.

Gigabit Ethernet Ports (Port 49~50):

The Switch is equipped with two Gigabit twisted pair ports, supported auto negotiable 10/100/1000Mbps and auto MDI/MDIX crossover detection function. These two ports can operate in half-duplex mode for 10/100Mbps and full-duplex mode for 10/100/1000Mbps.

Note: When the port was set to “Forced Mode”, the Auto MDI/MDIX will be disabled.

mini-GBIC (SFP) Ports (Port 49~50):

The Switch is equipped with two mini-GBIC ports, supported optional 1000BASE-SX/LX mini-GBIC transceivers.

Port 49 and 50 are the same ports with the mini-GBIC no.49 and 50 ports, when the mini-GBIC transceiver is plugged in, the device will activate mini-GBIC, and the RJ-45 port will be disabled.

Reset:

The Reset button is to reset all settings back to factory defaults.

Note: Be sure that you record the setting of your device, or else all settings will be erased when pressing the “Reset” button.

Rear Panel

AC Power Connector:

This is a three-pronged connector that supports the power cord. Plug in the female connector of the provided power cord into this connector, and the male into a power outlet. Supported input voltages range from 100-240V AC at 50-60Hz.
