old sparc2 twisted pair cable problem

[Guest_imported]

I recently came upon a few sparc2s and figured they would be good systems to familiarize myself with unix. Unfortunately, whenever I boot them up, I get the following repeating error:

no carrier:twisted pair cable problem or hub link test disabled?

Any help would be appreciated.

They are not attached to a network, and expect to be. I tried to remain child-like, all I acheived was childish.

Enable or disable the Link Integrity Test in the NVRAM by setting the parameter tpe-link-test? to either true or false:

ok> setenv tpe-link-test? false
ok> reset

This setting must match the configuration of the 10BaseT hub. If the hub does a LinkIntegrity Test, set this parameter to true. If not, or no hub is present, set it to false.

Reset saves any new setting permanently.

Thanks for the help Apricot except I have one more question. How do I get into the NVRAM? Im very new to unix so I really dont know any of the commands or anything.

Hi Cyrnil

You must make in a Terminal : init 0

Then are on then open boot prompt (ok>)!

some commands:

Displaying the Configuration variables:

Ok> printenv

Changing variable settings:

Ok> setenv tpe-link-test? false

controlling:

Ok> printenv

Reset the value of variable to the factory default:

Ok> set-default variable

Reset variable values to the factory defaults

Ok> set-defaults

You must make now the following steps:

Terminal: # init 0

OpenBoot:

Ok> setenv tpe-link-test? false
Ok> reset

and then boot
