Valentine subcluster switches (Nortel 4548GT)
The 4500 series Nortel switches are different from all others. A few hints:
- The serial port setting is 9600 8N1 with NO flow control
- Before the serial port will work, the dip switch on the back of the unit MUST be set to "BASE". If it is set to "Unit select" you will never get any reasonable response out of the serial port!
- Configuration of the unit, except for its own IP address, initally proceeds ONLY over the IP interfaces, NOT the serial console. However, starting the QuickConfiguration utility and then interrupting it with ^C gets you to a reasonable state. Use ^Y again to enter the console mode.

Net conclusion: avoid these switches if you can, since their config options are weird and nonstandard, and documentation is ... well, what about documentation?!
