There are serveral ways but, if you have a serial console cable you can set the IP using the following process:
- Get a serial console cable. Note that I went through several of them before I found one that would let me SEND characters to the device; I could see the switches boot activity but nothing I typed would appear on the console window… so if you have this problem, get another cable!
- Get a terminal program. Windows Vista and 7 removed HyperTerminal (which is quite annoying) but you can download a free, fully functional version for 30 days from hilgraeve.com/hyperterminal-trial .
- Start your HyperTerminal using the following settings: connect using COM1 (or whatever port you are using) 19 200 bits/sec 8 data bits No parity 1 stop bit No flow control
- Power up your 4200G (or similar aged 3Com switch)
- In the Hyperterminal Window you will see something like, and you will have just a second or two press CONTROL+B to enter the book menu:
