Four Dual

Each interface has one 1000 Base-T copper RJ-45 port and one Small Form-Factor

Personality

Pluggable (SFP) fiber port, with one port active at a time.

Interfaces

 

• 4 100/1000 Mbps RJ-45 Gigabit Ports:

 

 

Connect these Gigabit Ethernet ports to high-bandwidth backbone network

 

Ethernet switches.

 

 

 

• 4 Mini-GBIC Slots:

Console Port

The console port is for local configuration of the Switch.

 

 

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 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.
