Connecting the Workstation to the Switch

1Connect the workstation to a front panel port using an Ethernet cable as shown in Figure 9.

Figure 9 Connecting a workstation to the Switch via a front panel port

To connect the cable:

aAttach an RJ-45 connector at one end of the Ethernet cable to the Network Interface Card (NIC) in the workstation.

bConnect the RJ-45 connector at the other end of the cable to one of the front panel ports on the Switch.

Do not interconnect the Switch to any other unconfigured Switch.

Configuring the Workstation with IP Information

You need to change the IP address and subnet mask of the workstation that you have connected to the Switch. Make a note of the existing settings so you can return to them later. Change the workstation to the following settings:

■IP address — 169.254.100.99

■Subnet mask — 255.255.0.0

Setting Up the Switch with IP Information

You are now ready to manually set up the Switch with IP information. You can do this using the Web interface or the command line interface (CLI) via telnet.

Using the Web Interface

1Power-up the Switch. This takes approximately one minute.

2Open a suitable Web browser and enter 169.254.100.100 in the Location Address field. This is the default IP address that is automatically assigned to an offline unit.
