Page 22 of the 3com user guide for your switch talks about how to use the console cable and how to connect to your pc, I included the link below for your manual, if you don't have it:

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.

Forgot ip address and password


To re-enable the Console access requires the SW2900 series to be reset to its default settings via the WEB INTERFACE
- Web Interface
- Device >Configuration >Initialize To change the Default User "ADMIN" password it is necessary to use the Console connection
-Console Interface
-Once the unit has successfully booted and the prompt presented
-Enter "password" (without "")
-Enter "admin" when the system prompts for User
-Press the "Enter" key when the system prompts for "Old Password" (the ADMIN password was reset by the Web Interface commands)
-Enter "" when the system prompts for the New Password (where "" is the new product ADMIN password)
-Enter "" when the system prompts to confirm the New Password In order to complete the configuration it is necessary to save the configuration via the WEB INTERFACE
-Web Interface
-Device > Configuration > Save
Symptom:
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.

Configuring a 3COM 3CRWDR200A-75 router as a repeater


SETTING A ROUTER AS A REPEATER 1. Connect your computer to the repeater router's RJ45 port with a LAN cable. 2. Open a browser, then enter the router's URL configuration's IP address, This is usually something similar to 192.168.0.1 3. Enter the configuration user name and password. The router will display the various router settings. 4. Go to the page that changes the IP address of the router. Changed the IP address so that it is not the same as the main router on the network, or any other network devices. If the main router on the network is set to 192.168.1.1 then the repeater router should use a higher number (ie. 10), such as 192.168.1.10 or higher, depending on how many devices are on your network. 5. Disable the repeater router's DHCP server. This setting should be on the same page as the IP address, (this may be different depending on the make of the router). When the main router is operating normally, this server assigns an IP address to every device that is connected to your network. Because this router is used as a repeater, the main router on your network will still issue the IP addresses. 6. Also turn off the DNS server, if it is activated. This function will be taken over by the main router. 7. Disable any firewall settings on the repeater router. This is usually in the "Security" section, depending on the make and model of your router. 8. Remove all in the "Port Forwarding" section. Some routers may refer to this as "Applications and Gaming," and it allows less-restricted access to the internet. 9. Set the operating mode switch to "Gateway" or "Switch" if applicable. Also, if the repeater router is a wireless router then disable the wireless access or set it to access point only. 10. Save the settings for each page, and reboot the router. When the router boots up, the changes will allow it to act as a simple repeater. 11. Now, place the repeater router in a new location and connect both routers with a Ethernet cable in each of the router's RJ45 LAN ports, and power it up both routers.

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!!

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.

Not connect from console port


Verify that the correct settings and cable/connectors (rollover cable, correct COM port specified) are being used when establishing the console connection.

From the manual-

3.9.2 Connecting to an IBM or Compatible Device

To connect an IBM PC or compatible device, running the VT terminal emulation, to an
Enterasys Networks module Console port (Figure 3-20), proceed as follows:
1. Connect the RJ45 connector at one end of the cable (not supplied) to the Console port on the
Enterasys Networks module.
Connecting to Console Port for Local Management
Hardware Installation 3-31
2. Plug the RJ45 connector at the other end of the cable into the RJ45-to-DB9 adapter (supplied
with the device).
3. Connect the RJ45-to-DB9 adapter to the communications port on the PC.
4. Turn on the PC and configure your VT emulation package with the following parameters:

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.
