Tiny Deathstars of Foulness

You have two switches and you’re thinking that you’ll use the GBIC from your old switch on you new switch.  You have an Xsan and you have a bunch of GBICs laying around and you want to know if they’ll work.  You have a fiber run and you want to use a transceiver.  Etc. This is a tricky question.  The GBICs should all work.  The general rule of thumb though is, if you use the same GBIC on both ends then you shouldn’t have a problem.  But, it’s also important that (for whatever reason) some manufacturers do require certain GBICs either to actually interface or just to support an interface.

Lost the password for your Qlogic?  You can TFTP a new firmware file into a 5xxx switch and then do a factory reset while it’s in maintenance mode (follow the instruction exactly as they are in the latest version of the manual for your switch).  Or if you have a serial adapter you can break the boot sequence by using the space bar during boot.  At the prompt use:

factory 1

If you factory reset it then the default IP address will be 10.0.0.1 again and the default password will be back to password.  If you have the password and just want to reset it back to factory defaults then you can use the following steps:
