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.

SOURCE: i forgot my admin password

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.

First,"There is usually a small button on routers that can be accessed with the tip of a pen or a paperclip. When you find that tiny button, hold your pen or paperclip down on it for approximately 10 seconds until the router resets itself to factory defaults."
After that, you can contact the manufacturer to get some helps if you still have problem.

Huawei GE optical port with 1310 SFP module can connect to Cisco 3750X GE ports with GLC-LH-SMD?


The Cisco switch will probably err-disable the port when you plug it in. The workaround is to add these commands:
Switch(config)#service unsupported-transciever
Switch(config)#no errdisable detect cause gbic-invalid
It'll either work or it won't!

Connecting a 3Com 2952 Plus switch to a Cisco 3750 switch


If you also have a standard copper cable (or a second fibre cable) connecting the two switches (for resilience perhaps?), this issue is probably being caused by something called Spanning Tree. This is implemented on switches as a 'loop avoidance' system, and can look like you have described with one end 'ip' and the other end no lights.

On the Cisco switch, get to a telnet/ssh/console session, log in and enter show spanning-tree and press enter.

have a look to see if the fibre interface has a status (sts column) of BLK. If it has, then this is called 'blocking' and will remain like that until you remove the second link to the other switch.

Hope that this has helped!
