The following table describes the port labels on the front panel.
3.1.1 Console Port
For local management, you can use a computer with terminal emulation software configured
to the following parameters:
•VT100
• Terminal emulation
• 9600 bps
• No parity, 8 data bits, 1 stop bit
• No flow control
Connect the male 9-pin end of the console cable to the console port of the Switch. Connect the
female end to a serial port (COM1, COM2 or other COM port) of your computer.
3.1.2 Gigabit Ports
The Switch has 1000Base-T auto-negotiating, auto-crossover Ethernet ports. In 10/100/1000
Mbps Fast Ethernet, the speed can be 10 Mbps, 100 Mbps or 1000 Mbps and the duplex mode
can be half duplex or full duplex.
An auto-negotiating port can detect and adjust to the optimum Ethernet speed (10/100/1000
Mbps) and duplex mode (full duplex or half duplex) of the connected device.
An auto-crossover (auto-MDI/MDI-X) port automatically works with a straight-through or
crossover Ethernet cable.
