CONNECTOR

DESCRIPTION

 

 

2 100/1000

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

Mbps RJ-45

switches or use them to daisy-chain other switches.

Gigabit

 

Ports

 

2 Mini-

Use mini-GBIC transceivers in these slots for fiber-optical connections to backbone

GBIC Ports

Ethernet switches.

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 48 10/100Mbps auto-negotiating, auto-crossover Ethernet ports. In 10/ 100Mbps Fast Ethernet, the speed can be 10Mbps or 100Mbps 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:
