No! no! no!  The 3b2 was one of the first supermicros to fully integrate power management with the system.   Yanking the cord would be unthinkable mainly because it was unnecessary.  The shutdown script would remove power to the the system once the system safely went down and buffers were flushed.   You could also depress this massive rocket switch on the side of the unit and it would kick off the powerdown script.  It is noteworthy that the 3b2 power switch was stateless...allowing human and computer to turn off the power.  

Finally, the 3b2 is probably the only system in the world with system diagnostics so in depth that they were nearly as significant as the operating system.   It’s a telecommunications thing.   Interestingly,  the color of the 3b2 was similar to a VAX Brown and White.

Puns aside, anyone who didn't consider pulling the plug was probably not someone who should be bringing the system down.

Or was experiencing too much resistance?
