To connect 2 computers without a hub/switch you need to have a cross-over cable. Normally a network cable only uses pins 1, 2, 3 and 4 with pairs 1,2 and 3, 6 on both ends. A x-over swaps the pairs on one end.

Go to a computer store near you and ask for one. Don't pay more than $10.

If you can't find one or it is expensive, let me know and I'll make an adapter for you and just charge around $5 for the parts and shipping. My email is fixya@pcsports.org and put "X-over Cable" as the subject.

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.

How do i Reset or break in to get reset my password on 3Com 2948 Baseline Switch 48Port SFP Plus


The resetting of the password requires the installation of a console cable to the console port.

Be sure the terminal emulator program is set to VT-100 management using compatible, 38400 baud rate, no parity, 8 data bits and Console connection one stop bit.

Use the included cable, or be sure that the pin-out complies with a standard null-modem cable

Once the cable is connected, reboot the switch. Type a Ctrl/C until you enter the failsafe mode. This will be denoted with the prompt: “CFE>”
At the prompt execute the following commands:

CFE> passwrd
CFE> reset -sysreset

At this point the password has been reset.
