CONSOLE

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

 

interface (CLI) via the console port.

 

 

24 10/100

Connect these ports to a computer, a hub, an Ethernet switch or router.

Ethernet Ports

 

 

 

Gigabit

Connect these Gigabit Ethernet ports to high-bandwidth backbone network Ethernet

Ethernet/ mini

switches or use them to daisy-chain other switches.

GBIC ports

Alternatively, use mini-GBIC transceivers in these slots for fiber-optical connections

 

to backbone Ethernet switches

 

 

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 10/100-Mbps auto-negotiating, auto-crossover Ethernet ports. In 10/100 Mbps Fast Ethernet, the speed can be 10 Mbps or 100 Mbps 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 100 Mbps or 1000 Mbps 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 (10/100 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.

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
