ES-2108/ES-2108-G User’s Guide
34 Chapter 3 Hardware Overview
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 also comes 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.
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
3.1.3 Mini-GBIC Slot
This is a slot for mini-GBIC (Gigabit Interface Converter) transceivers. A transceiver is a
single unit that houses a transmitter and a receiver. The switch does not come with
transceivers. You must use transceivers that comply with the SFP Transceiver MultiSource
Agreement (MSA). See the SFF committee’s INF-8074i specification Rev 1.0 for details.
