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 fans 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 following table shows the physical and logical slot numbering, IPMB addresses and
hardware addresses in a Centellis 4410 shelf. Physical slots 6 and 9 are hub slots, all other slots
are node slots.
5.2.3 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 119 ). Therefore, changing the
shelf address also changes the shelf manager IP address.
