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 24 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.
There are two Dual Personality interfaces (Gigabit Ethernet/mini-GBIC ports). The mini-
GBIC ports have priority over the Gigabit ports. This means that if a 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 ports 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 (100/
1000Mpbs) 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 Slots
These are slots 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.
Console Port Only connect this port if you want to configure the Switch using the command line
interface (CLI) via the console port.
