Iv'e got a MVax 3600, so yours may be different...
The 3 position switch with:
 a face profile ==> presents a language choice menu at power-up;
 the arrow points at a 2 posistion boot action switch:
   dot in circle  (halt after tests) and dot out of circle (autoboot);
 a circular arrow ==> continous self-tests IIRC.

Huge and heavy..... ;-})
The 3400 is also faster in terms of VUPS (VAX Units of Performance). 
These numbers are relative to an 11/780; the MV3600 runs 2.8, an uVII is 
~ 0.9. The MV3400 runs at about 2.4.  For comparison, an 11/750 is 
0.6!!! There is a web page off the Port-VAX page that has a summary of 
most of the range of VAX and Alpha systems:       
     http://www.anglia.ac.uk/~systimk/History/Vaxes.Txt

and a NetBSD/VAX FAQ:  http://vaxine.bitcon.no/
