4 Identifying External Components
This chapter describes the front panel, rear panel, and LED indicators of the Switch.
4.1 Front Panel
The figure below (Figure 3) shows the front panels of the Switch.

LED Indicator:
Comprehensive LED indicators display the status of the switch and the network (see the LED
Indicators section below).
Fast Ethernet Ports (Port 1~24):
These ports support network speeds of 10Mbps and 100Mbps, and can operate in half- and full-duplex
transfer modes. These ports also support automatic MDI/MDIX crossover functionality providing true
“plug and play” capability. You only have to a device to the switch using a straight-through cable,
regardless of whether the device is a computer, switch and hub.
Gigabit Ethernet Ports (Port 25~26):
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.
Mini-GBIC Ports (Port 25~26):
The Switch is equipped with two mini-GBIC ports, supporting standard fiber mini-GBIC modules.
These ports use the same ports as the gigabit Ethernet ports. When a mini-GBIC module is plugged
into the switch, the corresponding gigabit Ethernet port will be disabled.

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 voltage
range is 100-240V AC at 50-60Hz.
