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.

Base from the description of your problem its only showing that some of the port on of your Ethernet switch is already getting bad and this usually happen on switch like this and eventually all port will go bad and will lead to the replacement of the device. With this type of problem you can first try to adjust the speed of your network card to 10 half duplex and check if that will correct the connectivity problem and if it does its just a sign that sooner or later the device is already getting bad and since its only a switch there's no firmware that we can load to it or even a reset button to bring the device back to its default settings.

My problem is i have all yellow ports flashing in 10 3com 3300 switches in the same time. please help me


  1. Using a Null-Modem Cable , hook up the Console port of the switch to an available COM port on a computer (cable must be able to provide serial port communication between 2 computers).
  2. Set up a Hyperterminal session to that COM port (e.g.: com1), with the port settings at 9600/8/N/1/N (. When the screen comes up blank with a blinking cursor, hit [enter] once or twice to bring up a login prompt.
  3. Alternative to 1 and 2 above, if there is a known assigned TCP/IP address for the switch, one can telnet to that address, hit [enter] once or twice to get the login prompt.
  4. Default logins to try are admin/(no password) or security/security. One of those 2 should bring up the management menu.
  5. To reset factory defaults, type SYSTEM[enter] then type INITIALIZE[enter]. This will reset everything that has been set up on the switch, with the exception of the TCP/IP address, if there is one. All other previous configurations will need to be re-entered.
  6. You can type in username "3comcso" and password "RIP000". It will ask you to reinitialize the switch. This will reset all settings including passwords.

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.

3com 3300 TM - all Ethernet port not working, power led flashing


A blinking power LED means that the switch is either downloading software, or is initializing which also includes running the Power On Self Test. You may have firmware issues with the switch and/or the switch is stuck in initialization mode. You may have to contact 3com regarding a warranty issue. Hope this helps. Good luck.
