The following table describes the port labels on the front panel.
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 10/100-Mbps auto-negotiating, auto-crossover Ethernet ports.
In 10/100 Mbps Fast Ethernet, the speed can be 10 Mbps or 100 Mbps and the
duplex mode can be half duplex or full duplex.
There are two pairs of 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 100 Mbps
or 1000 Mbps 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
(10/100 Mbps) and duplex mode (full duplex or half duplex) of the connected
device.

Ethernet
Ports
Connect these ports to a computer, a hub, an Ethernet switch or router.
Gigabit
Ethernet/
mini GBIC
ports
Connect these Gigabit Ethernet ports to high-bandwidth backbone network
Ethernet switches or use them to daisy-chain other switches.
Alternatively, use mini-GBIC transceivers in these slots for fiber-optical
connections to backbone Ethernet switches
