RE: Even dumb tubes expire

Hi Joe

I don't remember the settings off hand, but if you are on V5R4 there are a
few settings in DST/SST that make it easier to switch back and forth between
LAN console and Twinax console while you are getting it set up. You may need
to get into DST by using a function 21 from the front panel to change the
settings the first time.

Mostly the settings I remember were to do with whether the console could be
taken over and whether DST/SST functions could only be run from the console.
While you are switching over, being able to run them from another device
makes things a lot more simple and practical. You will also be able to tell
the system where your console card is a lot more simply on V5R4 using the
SST functions.

Maybe someone else can point you at the specific settings - I don't have a
machine I can look at right now.

Regards
Evan Harris

Subject: Even dumb tubes expire

A couple of nights ago we had a grand thunderstorm here.  My systems are 
all on Tripp UPS devices, so they never even so much as flicker, but we 
had a strike maybe 30 feet from the house and we all felt it.  A little 
later I checked the logs and noticed my console (an true blue IBM 
console) was reporting failures.  I powered it off, varied the 
controller and it seemed to be okay, but today it started acting up 
again.  It would connect, be okay, then cycle out.  I replaced it with a 
standby Lynx model, but that's it for that poor machine.

So, while dumb tubes are reliable, they aren't immortal.  And thus comes 
the issue.  I'm on my last backup terminal.  I don't know if I want to 
buy a couple more; they're cheap enough, but they do take up space.  Can 
I take my model 270 with V5R4 and use a LAN console with it?  It's a 
9406-270, 22A4 feature code, if that helps anyone.
