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 #12. The physical address and the physical slot number are identical for AdvancedTCA
blades. The physical addresses of other FRUs like PEMs and blowers identify the type of the FRU
and a particular FRU of that type.
Physical and logical slot numbering differ in a shelf with dual star fabric topology.
Logical slots are numbered starting from the hub slots. Every slot has a unique logical slot
number with a maximum of 14 slots per shelf. 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.
Physical slot numbers (range of 0 to 255) start with the lowest number at the leftmost physical
slot incrementing to the right. Physical and logical slot number may be different. The shelf FRU
ROM provides a mapping of physical slot numbers to logical slot numbers for each slot.
The table below shows the physical and logical slot numbering, IPMB addresses and hardware
addresses in a Centellis 4100 shelf. Physical slots 7 and 8 are hub slots, all other slots are node
slots.
6.2.3 Shelf Address
The shelf address (SA) is used to calculate the shelf manager IP address on the out-of-band
interface (see
Virtual IP Address on Out-Of-Band Interface
on page 177 ). Therefore,
changing the shelf address also changes the shelf manager IP address.
