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 Gigabit Ethernet Ports
The Switch has 1000Base-T auto-negotiating, auto-crossover Ethernet ports. In
10/100/1000 Mbps Fast Ethernet, the speed can be 10 Mbps, 100 Mbps or 1000
Mbps and the duplex mode can be half duplex or full duplex.
An auto-negotiating port can detect and adjust to the optimum Ethernet speed
(10/100/1000 Mbps) 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.
Four of the 1000Base-T Ethernet ports are paired with a mini-GBIC slot to create a
dual personality interface. The Switch uses up to one connection for each mini-
GBIC and 1000Base-T Ethernet pair. The mini-GBIC slots have priority over the
Gigabit ports. This means that if a mini-GBIC slot and the corresponding GbE port
are connected at the same time, the GbE port will be disabled.
When auto-negotiation is turned on, a Ethernet port negotiates with the peer
automatically to determine the connection speed and duplex mode. If the peer
Ethernet port does not support auto-negotiation or turns off this feature, the
Switch determines the connection speed by detecting the signal on the cable and
using half duplex mode. When the Switch’s auto-negotiation is turned off, an
Ethernet port uses the pre-configured speed and duplex mode when making a
connection, thus requiring you to make sure that the settings of the peer Ethernet
port are the same in order to connect.
