Connecting the Cables

1Insert the DB-9 (or DB-25) female connector of the Console cable into the serial port on the PC (the Console terminal).

2Insert the RJ-45 connector of the cable into the Console port on the switch.

Setting the Terminal Set baud rate to 9600, data bits to 8, parity check to none, stop bits to 1, flow Parameters control to none, and terminal emulation to VT100.

This section will tell you how to set the terminal parameters, taking a PC running

Windows 98 Hyper Terminal as an example.

Step 1: Start PC, and run terminal emulation program (such as Terminal of Windows3.1, or Hyper Terminal of Windows 95/Windows 98/Windows 2000/Windows NT/Windows XP/Windows ME) on PC.

Step 2: Set parameters in the Hyper Terminal of Windows98.
