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 port each. The mini-
GBIC port has priority over the Gigabit port. This means that if the 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 port 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.

DESCRIPTION
Only connect this port if you want to configure the switch using the command line
interface (CLI) via the console port.
Connect these ports to a computer, a hub, an Ethernet switch or router.
This is not available on ES-2108.
Connect this Gigabit Ethernet port to high-bandwidth backbone network Ethernet
switches.
Alternatively, use a mini-GBIC transceiver in this slot for fiber-optical connections to
backbone Ethernet switches.
This is a 100-Base FX fiber-optic module and is only available on the ES-2108-LC.
Use the fiber optic cable to connect this uplink port to a backbone Ethernet switche.
