reset the password on a Dell PowerConnect M6220
Hello, I am trying to reset the password on a Dell PowerConnect M6220. I can login to the CMC via the https webpage but dont see how to do it from there.
So I am trying to plug in a USB serial cable into the console port and reset the password via a console session using teraterm but when i do this all i get is a blank screen.
Serial settings are:
Cable: Null Modem
Bits per second: 115200
Data bits: 8
Parity: None
Stop bits: 1
Flow control: None
Any ideas on how i can access telnet access to the device to reset the pwd successfully
thanks
Kevin

You can connect to the internal console port of the switch via the CMC CLI
Telnet to the CMC, then connect switch-a1 ( or a2 or b1 etc etc )
That will give you the > prompt, then either delet the startupconfig and reload, or put in you own username and password - do remeber that you can set it on the out of band interface or in band, by slecting the appropriate interface

On the boot menu there is an option for password recovery. This would mean that the console connection needs to be working. Here are the settings that need to be used.
1. Connect to the switch using the supplied USB/null modem cable from a computer serial port.
2. Start a terminal program such as HyperTerminal.
3. Set the terminal program to:
○ 9600 baud rate
○ 8 data bits
○ No parity
○ 1 stop bit
○ No flow control
4. Press twice or three times to initiate console communications.

Daniel,
I have tried logging in via the console cable and its connected ok but just doesnt do anything when i hit the enter button. So maybe i need to do something on the Dell chassis first to enable the console connection - would that be correct. Or do i need to do something on the boot menu?
I do have access to the Dell Chassis M1000e so i can see the Dell switches ok from there but cant login to them via the webpage.
regards,
Kevin

If the serial connection is not working, then you'll need to rely on the CMC connection. If the CMC connection allows you to see the boot menu, I would use the boot menu option to recover password. If it does not let you see the boot menu, then in order to get rid of the password you need to clear the current configuration and start over.
• delete startup-config or simply del start.
• reload

Telnet to the CMC
connect switch-a2
enable
configure
config#username root password calvin level 15
exit
Login to a2 via its IP address on the webpage or telnet
Thanks again Cerbera
Much appreciated
