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 Eight 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.

The ES-2108-G and ES-2108PWR also come with a Gigabit/mini-GBIC slot each. The mini-
GBIC slot has priority over the Gigabit port. This means that if the mini-GBIC slot 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 slot 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 (10/100Mpbs)
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
