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 Ethernet Ports

The Switch has 10/100/1000 Mbps auto-negotiating, auto-crossover Gigabit Ethernet ports. In 10/100/1000 Mbps Gigabit Ethernet, the speed can be 10 Mbps, 100 Mbps or 1000 Mbps and the duplex mode can be half duplex (for 100 Mbps) or full duplex.

An auto-negotiating port can detect and adjust to the optimum Ethernet speed 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.

3.1.2.1 Default Ethernet Settings

The factory default negotiation settings for the Ethernet ports on the Switch are:

•Speed: Auto

•Duplex: Auto
