You forget the password for the "admin" user account and can no longer perform important management operations. Wants to reset 3824 3com switch via console - solution.gif Use the password recovery method outlined below to define a new password for the "admin" user account:

  1. 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.

    note.gif You must use the console port to recover the passsword. If you attempt the recovery method using the network, the password will be rejected.

  2. Perform a hard reset on the Switch whilst it is in password recovery mode by switching it off, waiting a few seconds, and sWants to reset 3824 3com switch via console - note.gif it on again.

    note.gif 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.

I forgot ip address and password and want to factory reset


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.

What is the default ip address for powerconnect 5212


By default there isn't one you need to use the serial cable and hook it up the console port and log into it with a terminal program such as hyper terminal or putty

Access denied


yes, you should be able to connect to the console port using a roll-over cable RJ45-DB9, connect using hyper terminal or similar using the com port settings 9600,8,N,1
You can then configure the switch from the CLI...

Have you set the 'Login' command on the VTY lines in the switch setup and an IP address on the management VLAN to connect to.
You also HAVE to have a password enabled on the vty lines in order to connect via telnet.

hope this helps.

Switch not connect hyper terminal


If you are connecting to the switch using the console port using a console cable. Make sure your settings for hyper terminal are on COM1 and the baud rate is 9600.

If you are trying to telnet, you will need to assign an IP address to the VLAN in order to telnet into the switch and configure a password or it will not let you in.

How do i Reset or break in to get reset my password on 3Com 2948 Baseline Switch 48Port SFP Plus


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.

Inherited 2 switches 3com 4228g (3c17403) password problem


I haven't worked with these switches but generally settings such as ip address and factory defaults can be set through the Console Interface (CLI). You will need a null-modem cable to access this and a terminal client (Windows Hyperterminal works).

Hope that helps

Procurve 2626 installation


You'll need to obtain a comms lead - connects into the console port of the switch then into an RS232 port on your laptop. Then, you will be able to connect using hyper terminal and you can give the switch an IP address, username, etc. Even a hard-reset won't allow you to configure an IP address as by default it needs to be configured through the lead. Will they not talk without being configured? If you just hard reset them, they should just behave as unmanaged switches.

I cann't connect to my switch


The primary connection method for those switches would be serial connection. In the box there should have been a DB9 serial to RJ45 cable. Hyperterminal default settings would allow you to connect.
