can't get into bootrom

[David_Byte]

I have a few used x450-48t switches that I cannot get to recognize the spacebar to get into the bootrom. I have tried from both my mac and a linux box using known good cables.

1.0.3.5 for the bootloader and 12.0.3b16 for the OS.

Any thoughts on how to proceed?

If I'm having trouble like that, I will hold the spacebar down while I am unplugging/plugging in the switch. That hasn't failed me yet.

finally got on using the linux box with minicom.. too bad 2 of the 3 switches I picked up have hardware issues..

have to be very quick... some of the older switches dont like the USB dongle serial connections... best way to do this is have the telnet session open and ready start hitting the space bar then plug it in and hope you can break into the boot process...
