chassis, rack

[milan2003_07]

Hello,


"Control hardware includes a Chassis (Rack), Power Supply, 1757-PLX52 Control Processor, XXX Interface, Redundancy Module, and I/O Modules. An optional Battery Extension Module (not shown) is also available. The Chassis is available in 5 sizes - 4, 7, 10, 13, and 17 slots."

What do "chassis" and "rack" mean in this context?

Thanks!!!

The chassis or rack is the case into which all of the other components go. With a choice of the number of slots, it is clear that there is some sort of backplane in the chassis.

Are "chassis" and "rack" the same or they mean different things?

Same.
