| Gigabit | This is not available on ES-2108. |
| Ethernet/ mini- | Connect this Gigabit Ethernet port to high-bandwidth backbone network Ethernet |
| GBIC port |
| switches. |

| | Alternatively, use a mini-GBIC transceiver in this slot for fiber-optical connections to |
| | backbone Ethernet switches. |
| 100 Base-FX | This is a 100-Base FX fiber-optic module and is only available on the ES-2108-LC. |
| Fiber-Optic | Use the fiber optic cable to connect this uplink port to a backbone Ethernet switche. |

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.
