Step 1 Start the terminal-emulation program and open a session if you are using a PC or terminal.

Step 2 Start a terminal-emulation session.

Step 3 Configure the baud rate and character format of the PC or terminal to match these console port default characteristics:

=B79600 baud

=B78 data bits

=B71 stop bit

=B7No parity

=B7 None (flow control)

If that don't work, try a restart, and if still no go, could someone have changed the default? Is this a redeployment?

If so, I'd try to figure out how to factory reset if possible. Not sure on those 2900s.

Its always possible its not set to the default settings. What Tredkill as given are the default settings. But if this is a used unit, its always possible that the previous owner did not have it set to default.

Play with your settings, and when you do find the correct settings, change the config register back to 0x0 to have the box go back to the default console settings of 9600baud.

If your feeling brave and feel like opening the box, you might see if there is a battery that you can temporarily disconnect to more forcably clear the NVRAM contents, and have it revert back to default settings.

i try all and i still get unreadeble characters but i setup ip address and password then i telnet on switch and its all ok i try terminal default but its the same again on console cable.. any one have idea ??

Read SCSI's reply. He tells you how to set the config to make sure the console stuff is set back to default. Then it should work.

Whenever unreadable characters appear over the console connection, rotate through different baud rates on your terminal software. 9600 is the default setting, but if you get a switches that someone may have had to send the IOS image over the console cable, the console baud rate might have been adjusted up to 56000 for the file transfer and never set back to the default 9600.

Something strange happening ...I tell you ppl about switch and how i get unreadable character and that kind a stuff so i did not know what is wrong with him so i send him go services...

Yes - keep trying different terminal baud rates -
