Connect the console cable, open a connection to the serial port via a utility such as PuTTY, and do the following: 1) Enter the user name "recover" and password "recover" to place your unit in password recovery mode. The unit will remain in password recovery mode for 30 seconds max. 2) Perform a hard reset by removing power, waiting 10 seconds, and then re-applying power. 3) Once the switch has rebooted, enter a new password for the "admin" user account. 4) Enter enable to leave password recovery enabled, or enter disable to turn it off. You are now logged in as the default "admin" user. Note: If password recovery has been disabled, the only way to recover access is to return the switch to 3com.
To re-enable the Console access requires the SW2900 series to be reset to its default settings via the WEB INTERFACE

SW2900 Baseline Switch - Default console access disabled following password change
From the web interface, the default user "admin" password is changed and console access is disabled Cause:
When applying the new password, by default
the service-type is set to "telnet". When applied, the default
"terminal" setting is removed thus disabling console access.
Connect some text-based terminal emulator such as Hyperterm, telnet,VT100, etc to the serial port. Configure the emilator to19200 Baud 8 plus none.
Switch the 4924 on and login using the user "recover" (without quotes) and password "recover" (also without quotes.
The switch will go into recovery mode. It will display a count-down starting at 30 seconds. If you power thye switch off before the count is up, the default password for the main administration account "admin" will be cleared.
After a few seconds, power the switch on and set a new admin password.
After loigging in again, take the option "GettingStarted". Configure the ip settings (best to use a static address) and eventually you will get to the "Initialize" option. Enter yes, and after reboot it will be at factory except for its ip address.
on a mac u have to go to finder, applications, uttility, network utility and in there under the info tab there is a drop down. in that drop down you have to choose network interface (en1) AND IT GIVES YOU THE IP ADDRESS
You forget the password for the "admin" user account and can no longer perform important management operations.
Use the password recovery method outlined below to define a new password for the "admin" user account:
Access the Command Line Interface from the console port and enter the user name "recover" and password "recover" to place the Switch in password recovery mode. The Switch remains in password recovery mode for a maximum of 30 seconds, before it returns to the CLI login prompt.
You must use the console port to recover the passsword. If you attempt the recovery method using the network, the password will be rejected.
Perform a hard reset on the Switch whilst it is in password recovery mode by switching it off, waiting a few seconds, and switching it on again.
You cannot use a soft reset operation to reset the password of the "admin" user account. This will end the password recovery procedure and return you to the CLI login prompt.
When the Switch has rebooted following the hard reset enter a new password for the "admin" user account.
