How reset 3com 4228g switch


If I remember correctly, there is a tiny hole at the back or on the side. Press a paper clip into it. The switch should do a full reset and then reboot. If its just locked up, I would switch off at the power for 15 mins and try let it do an auto restart itself. Do this before you go doing a full button press reset as you may lose any or all updates the switch has had loaded into it.

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!!

How to reset the switch of 3C16475CS? (if no reset button)


It's called a recovery button and it is inside the switch. You need a paper clip or pin to press it. It is the tiny hole on the back of the switch

Page 9 shows the hole it is labeled "8"

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.

1.
3com default ip: 192.168.1.1
username: n/a
password: admin
or
2.
3com default ip: 192.168.1.1
user-name: adminttd

3com default ip 192.168.1.1
user-name: admin
password: n/a
or
4
3com default ip 192.168.1.1
user-name: n/a
password: PASSWORD
OR
5
3com default ip 192.168.1.1
user-name: root
password: !root

ok try
this
Note that at time you will need to set your local ip of your pc from which you are acess the device to the same range...
That is for example 192.168.1.10


Good luck
