3.2.1 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.

3.2.2 Gigabit Ethernet Ports

The Switch has 1000Base-T auto-negotiating, auto-crossover Ethernet ports. In 100/1000 Mbps

Gigabit Ethernet, the speed can be 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 (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.

Four 1000Base-T Ethernet ports are paired with a mini-GBIC slot to create a dual personality

interface. The Switch uses up to one connection for each mini-GBIC and 1000Base-T Ethernet pair.

The mini-GBIC slots have priority over the Gigabit ports. This means that if a mini-GBIC slot and

the corresponding GbE port are connected at the same time, the GbE port will be disabled.

Note: The dual personality ports change to fiber mode directly when inserting the fiber

module.

When auto-negotiation is turned on, an Ethernet port negotiates with the peer automatically to

determine the connection speed and duplex mode. If the peer Ethernet port does not support auto-

negotiation or turns off this feature, the Switch determines the connection speed by detecting the

2 or 4 Dual

Personality

Interfaces

Each interface has one 100/1000 Mbps RJ-45 port and one Small Form-Factor Pluggable

(SFP) slot (also called a mini-GBIC slot), with one port or transceiver active at a time.

Note: The ports change to fiber mode directly when inserting the fiber module.

• Two or four 100/1000 Mbps RJ-45 Ports:

Connect these ports to high-bandwidth backbone network Ethernet switches using

1000Base-T compatible Category 5/5e/6 copper cables.

• Two or four Mini-GBIC Slots:

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

switches.

Console Port The console port is for local configuration of the Switch.
