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.

Superstack 3 3848 reset at default


Hi ! I think this solution should be approached. Because this procedure is the same for switches 3Com and HP A-series with Comware OS.

1. Connect light blue console cable between a computer (serial) and the 3COM switch (RJ45 console port)

2. Open PUTTY or Xshell or HyperTerminal with a serial connection and the following settings (19200, 8, 1, N) If not connected may use 9600 or 115200 bps

14. If you type "summary" you will see all the switch details.

Amongst these details are the IP address of the switch. If you have DHCP on your network this switch is connected to it will receive one as in my case below, so I can now configure the rest via a web browser.

If not you can use the "ipsetup" command to set a static management IP and access via a web browser.

15. Once you can access the web management page for the switch make sure you set a strong password for "admin" and store it in a secure encrypted location for next time.

16. Don't forget to save your new configuration! Otherwise the switch will be at factory defaults if the power goes off!!

Hello,

I have not worked with 3Com switches only Cisco, but I thought I would post this as I found it when googling:

multicast routing-enable pim
on the vlan interfaces:

interface Vlan-interfacex
ip address ***.***.***.*** ***.***.***.***
igmp enable
pim dm

Those commands should help you get multicasting to work. notice, Vlan-interfacex means you will have to do it for each Vlan you created. Some switches do not include multicast support in their base models but make you buy additional licenses to enable it. Cisco is like that, not sure about 3Com.

I forgot my admin password on my 3com baseline switch 2226-sfp. i can't remember. Can you please help mo to reset my baseline switch to reset the password only. Thanks jenry


If it's the Power Plus (3C16475BS) model, there should be a reset button inside a small hole on the back. "10 - Recovery Button" Inserting a paperclip or similar to reset. If it's not the Power Plus model and is in fact (3C16475A), this is an unmanaged switch, with no administrative capabilities. You don't need a password.

Hoe do you reset a 3Com Superstack3 3870 to factory defaults?


Username: recover
Password: recover

*** Password Recovery Mode ***
The administrative password will be cleared if a hard reset operation is
carried out on the device within 30 seconds.
If a hard reset operation is not carried out during this period, the device
will return to the CLI login prompt.

Wants to reset 3824 3com switch via console


You forget the password for the "admin" user account and can no longer perform important management operations. 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 switching 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.

  3. When the Switch has rebooted following the hard reset enter a new password for the "admin" user account.
