CONNECTOR

DESCRIPTION

 

 

Console Port

Only connect this port if you want to configure the switch using the command line

 

interface (CLI) via the console port.

Management

Connect to a computer using an RJ-45 Ethernet cable for local configuration of the

Port

switch.

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 Ethernet Ports

The switch has 24 100/1000Mbps auto-negotiating, auto-crossover Ethernet ports. In 100/ 1000Mbps Fast Ethernet, the speed can be 100Mbps or 1000Mbps and the duplex mode can be half duplex or full duplex.

There are two pairs of Gigabit Ethernet/mini-GBIC ports. The mini-GBIC ports have priority over the Gigabit ports. This means that if a mini-GBIC port and the corresponding Gigabit port are connected at the same time, the Gigabit port will be disabled. The speed of the Gigabit Ethernet/mini-GBIC ports can be 100Mbps or 1000Mbps and the duplex mode can be half duplex (at 100 Mbps) or full duplex.

An auto-negotiating port can detect and adjust to the optimum Ethernet speed (100/ 1000Mpbs) 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

•Flow control: Off
