I've done a fair amount of searching both on Nekochan and in SGI's archives, and could not find an answer to this question. What is the Diagnostic position of the MSC keyswitch used for? It's not needed to actually use POD mode, and the boot hardware diagnostics level is set with the MSC dip switches. Does it do actually do anything?

Sure. It directs diagnostic output to the DIN8 port located on the MSC or the DB9 alternate console port located in the lower right corner of the rear panel.

Are you saying it selects which of those two physical ports to direct output to, or that it enables additional diagnostic messages sent to both ports simultaneously? I'll try it out again when I get home this evening. (I've tried before but never noticed anything.)

I have observed that when the key is the On position, diagnostics info during boot is output on the DIN8 port. This info seems to contain much (but not all) of the same info that is output to the serial console.

The two ports are in parallel, but you shouldn't connect to them simultaneously.

Comes in handy when you want to communicate with/issue commands to the MSC. As you've noticed, diagnostic info goes there even if the key isn't turned, but without the key turned you'll have to enter a password to communicate with the MSC. If you're lucky and no one has set the MSC password, the default/unset password is "none" (so the command to try would be "control+t pas none"). If there's a preexisting password you can use the key to get MSC command access, and use the clear command ("control+t clr") to reset *all* of the MSC settings back to the factory defaults (though if there's any preexisting settings that your system needs that might not be a good idea). All MSC commands are three characters in length, and are normally prefaced with a "control t" combination keypress. MSC responses should always include "OK", followed by the answer to your query (if you've asked the right question). There are a number of MSC control features, from the very useful fan speed control to the slightly frivolous ability to display custom text in the MSC's LED display.

On the odd chance you aren't already familiar with MSC commands, there's a few scattered through this thread: viewtopic.php?f=14&t=11658&p=92544&#p92544

Someone should update the MSC nekochan wiki topic ( http://www.nekochan.net/wiki/MSC ) with more info from that thread...

Good idea. I just did so and added other info I've found in other places as well.

My Onyx2 has developed some problems (sporadic kernel panics maybe tied to a specific node board) after sitting unused for a few months and moving to a new home and I'll be playing around with it a lot in the next few days to figure out what's going on.

I tried out the Diagnostic switch position again this evening and other than bypassing the password (which was actually none on my system), it doesn't seem to really add anything to the messages I normally see on the MSC.
