E450 Console: output ok but no input

See if you have the command 'eeprom' available. If you do, run it and look for these two lines in the output:

output-device=ttya

input-device=ttya

If your input device is not ttya (which on my system is the serial console port), perhaps you need to set it to be. I have a Netra system which has a dedicated keyboard port as well as the plain old serial console port. If your input device is presently defined as 'keyboard' then maybe your system has a dedicated keyboard port too and you need to get a keyboard hooked up to that port at least temporarily to give input to the system? I don't know if you already have access to it via the network.

If you have no network access and no Sun keyboard to connect to the dedicated keyboard port then maybe there is some way you can clear the system NVRAM configuration (and hopefully have it default to the serial port for input and output?). I'm not sure. Good luck though :)

Hi,

Did you ever resolve this issue? I have the same problem with an E450 but the key is in the normal ON position pointing straight up.

I've checked eeprom and both output-device=ttya and input-device=ttya

I get output to the console but the keyboard does nothing. The cable and vt100 both work on another e450.

Cheers,

Paul.
