From the 3Com knowledge base:

********************
Baseline Switch 2948 – How to reset password on switch 2948
Problem:      How to reset password on switch 2948

The resetting of the password requires the installation of a console cable to the console port.

Be sure the terminal emulator program is set to VT-100 management using compatible, 38400 baud rate, no parity, 8 data bits and Console connection one stop bit.

Use the included cable, or be sure that the pin-out complies with a standard null-modem cable

Once the cable is connected, reboot the switch.  Type a Ctrl/C until you enter the failsafe mode.  This will be denoted with the prompt: “CFE>”

At the prompt execute the following commands:
CFE> passwrd
CFE> reset -sysreset

At this point the password has been reset.

Try starting while holding the Command-Option-Shift-Delete keys all at the same time and see if it will let you startup/install.

Do you have any external drives you could install Tiger on first?

If the above doesn’t work, try this:

1. Start Mac and hold Option-Command-O-F keys
2. When the grey screen gets loaded type reset-nvram then press Return key
3. At next prompt type reset-all and the Mac will restart

See if that will allow install.
