Understanding the Location Coordinates

This section describes the numbering system used to identify components of the library. The library location coordinates
contain the following digits: [Module],[Column],[Slot].
9U Library Expansion Module is numbered.
Figure 1 Library Location Coordinates
Modules
Library modules are represented by the first digit of a library coordinate. Modules are identified relative to the 5U Library
Control Module.
The 5U Library Control Module is numbered 0 (zero). 9U Library Expansion Modules stacked above the 5U Library Control
Module are addressed with positive integer digits depending on their position above the 5U Library Control Module. For
example, the 9U Library Expansion Module stacked directly above the 5U Library Control Module is number 1. The 9U Library
Expansion Module stacked directly above module 1 is number 2, and so on.
Modules stacked below the 5U Library Control Module are numbered with negative integer digits, also depending on their
relative position to the 5U Library Control Module. For example, the 9U Library Expansion Module stacked directly below the
5U Library Control Module is number –1. The 9U Library Expansion Module stacked directly below module –1 is number –2,
and so on.
