The physical address describes the physical location of an FRU in the shelf. This location is
required when an operator has to handle an FRU, for example, exchange the AdvancedTCA
blade #2. The physical address and the physical slot number are identical for AdvancedTCA
blades. The physical addresses of other FRUs like PEMs and fans identify the type of the FRU and
a particular FRU of that type.
Physical slot number 1 is assigned for lower slot and the physical slot number 2 is assigned for
upper slot. For each slots, the shelf FRU ROM provides the mapping between physical slot
numbers and logical slot numbers.
Every slot has a unique logical slot number. These logical slot numbers are used to determine
the channel mapping between the slots according to the AdvancedTCA specification PICMG 3.0,
chapter 6.5.6.
The following table shows the physical and logical slot numbering between IPMB addresses
and hardware addresses in your system.
