I forgot the piece of documentation that I use for that specifically; the
boxology diagram. That's a visio[1] detail related to chassis and card slots
that correlate directly to the bill of materials for inventory and install
management. I tend to drop ship the entire order to the facility instead of
shipping and then reshipping to save on the shipping costs. This is a
prefernce thing since the costs for 20U and shipping are probably not that
great as compared to doing this for 200 racks.

One other thing that is important for documentation. Pics of the completed
install. I won't release payment until there is an acceptance, either onsite
or via pics and an operational service.



1. Most vendors have visio objects to give you upon the asking. Visio itself
comes with many, and there are vendors like NetZoom who make a living
providing chassis and card objects for this level of detail.
