Dimension Ethernet Switches

Your switch comes with auto-negotiating, auto-crossover ports. Depending on the model, these ports are either fast Ethernet (10/100 Mbps) or Gigabit (10/100/1000 Mbps) ports. Auto-negotiating ports can detect the speed of incoming transmissions and allow either half duplex transfer mode (10/100 Mbps only) or full duplex mode. Auto-crossover means that you can connect the switch to a computer or hub using either a straight-through or a crossover Ethernet cable.

Network Cables

You can use unshielded twisted pair (UTP) or shielded twisted-pair (STP) Ethernet cables for RJ-45 ports. Make sure the cable length between connections does not exceed 100 meters (328 feet). The following table describes the types of network cable used for different connection speeds.

The LNK/ACT LED should flash when data is being sent between your switch and a connected device.

Power Connection

Connect one end of the supplied power cable or power adaptor to the power receptacle on the switch and the other end to the appropriate power source. The PWR LED should turn steady on if the switch is receiving power.

Console Port (Managed Switches Only)

If your switch has a console port, you can use a terminal emulator for local management. Connect the male 9- pin end of a 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. Configure the computer with terminal emulation software to the

following parameters:

 

 

VT100 terminal emulation

No parity, 8 data bits, 1 stop bit

9600 bps

 

No flow control
