Switch CNET CSH-2402G PASSWORD RECOVERY

I am assuming you will still need console connection to do a password recovery.. however, here is the link to one password recovery doc that may help.

Unless I'm missing something, you can't. This is a basic switch with no advanced application aware features.

No manual. Maybe a pinhole reset switch?

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.

Don't know about a special program, but you can try to use Centrastage (www.centrastage.com)
It's a remote management software and it seems like it can be useful for you.

interConnecting two switches will need a crossover cable. Please use a crossover cable.

Check the power adapter with a multi-meter. The voltage on the plug that connects into the Ethernet switch, the voltage reading should be slightly higher than the voltage that is printed on the label on the bottom of the adapter.
If the voltage is zero or very low then the adapter is faulty and needs to be replaced.
If the voltage of the adapter is OK then the Ethernet switch is faulty and you need to buy a new one.

This particular 8-port Ethernet switch/hub has auto-negotiation on both speed as well as MDI, MDI-X.  Therefore, the problem is not with your switch/hub, it's probably with the particular port that you're connecting it to on your Router.  Make sure that it's the LAN side, not the WAN side.

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

The login you are using should have placed you in super-user mode. Are you connected directly to the switch with a serial console cable?
