RE: Stacking AS/400s?

Larry, Bob,

Thanks for the replies. 

We put the 810 on top of the expansion cabinet, with a non-skid pad. No fuss
and our CE loved it. I didn't know how much structural strength the
expansion tower had, and our 810 has more mass than it looks. It's been 4
weeks and no problems at all.

Thanks,
Loyd

Bob,

  Just to keep people out of trouble:

  a) You CANNOT field install a 5074 or 5094 in a rack. IBM doesn't 
offer such a feature because the buggers are just too damn heavy. You 
can as you say order a 5294 and get a pair already racked. Note that for 
dual line cords you need to order TWO kits (one for each 5094)

 b) The 0551 is the rack itself. You do need to order one of those to 
rack any iSeries. Technically though once you get the rack mount 
features for the server you have, they will fit in any 19" rack. It is 
up to YOUR CE to decide if he likes the arrangement or not. This is 
because he is the one who's life and limb is at risk if the rack is a) 
too wimpy or b) unstable.

 c) for i825's IBM has withdrawn the field install in rack kit since the 
machine is now CE install. You need to order the bugger in a rack. The 
rack kit consumes an additional 2U of rack space.

 d) for i810's and i270s' you need both the rack feature (0137 I think) 
as well as a system unit expansion. Again the rack kit consumes 2U of 
rack space.

 e) for i820's you need a band saw to make it thinner.  This is not an 
IBM supported modification nor is it reccomended ;-)

 f) Now for Loyd's question. Sure we've piled i810's on top of 5094's.  
The 5094 tower would probably hold my Dodge Ram and I lift the i810 up 
there myself with no trouble at all.  We route the cables down through 
that slot in the top of the 5094 back cover.  We DO reccomend you add 
some sort of non-skit pad to keep the i810 from being pushed off by 
accident.  Since there is no reason to remove the top of 5094s (like 
there was with 6xx and 7xx systems) the IBM CE's in our neighborhood 
have just siad "Cool. Easy to work on!"

  Hope this helps!
