If I read the question correctly, the method of racking a server depending on rack type (2 post or 4 post).
A two post rack mount server would install into a telco rack of two posts.

The key difference is stablization and adjustability. With 4 post you can install a rail system that helps you to slide the server forward (for open the case) without urack the server. With 2 post, you just lock your server in one position and unless you don't have anything on the top of the server (clear space), you will not be able to open the case by sliding the server forward.

Did you mean whats the difference between a 2 post server rack and a 4 post server rack?

A two post rack suspends the servers from the middle, a 4 post one has them mounted on runners that run from front tp back.

There are very few 2 post server racks because they aren't generally strong enough, 2 post racks are normally just used for patch panels and network switches.  here are some 2 post server racks, they look rather unsafe if you mount big servers in them. www.rackmountmart.com/html/opSr.htm

4 post racks are much more common, because they're much stronger with posts in all 4 corners. www.rackmountmart.com/html/bbServer.htm
