Sun Environmental Requirements


I just found a GREAT use for the new "Sun-3, Sun-4 Hardware Configuration
Guide". Ever wanted to do *something* to that stupid Sun but were afraid of
doing real damage? Have the questions "How loud do I have to yell at it before
it hears me?" or "I wonder what would happen if I dropped it out of the
window?" ever crossed your mind? Fear no more. Just ask Sun and all your
questions will be answered.

Drop				Based on weight of packaged unit
    Compression			Tested to failure as shown in Table A-2
	Compression Rate	Load must exceed the greates of the following
				1) 4 times expected load in storage

				3) 300 lbs

Stability			Minimum tip of 22 degrees without
				tipping over

Tip Over			If unit does not meet stability requirement,
				it must be tipped from the point of
				equilibrium in that axis
