Shelf Root This logical resource represents the shelf.
There is exactly one created by each HPI
server.
This resource is implemented as described in
the mapping specification. However, the format
of the entity instance of the shelf resource is
Radisys-specific.
(SAHPI_ENT_ADVANCEDTCA_CHASSIS, Shelf Id)
The entity instance of the shelf resource is the first 4
bytes of the shelf address, and is an encoding of the
physical location of the shelf.
Static
SPM slot Shelf This logical resource represents the slot
occupied by a shelf peripheral module (SPM).
(SAHPI_ENT_OEM_SPECIFIC, SPM Site Number) Static
Virtual SPM
slot
Shelf This logical resource provides support for the
logical virtual SPM in the shelf. The virtual SPM
represents the functionality accessible only
through the active SPM.
(SAHPI_ENT_OEM_SPECIFIC+2, 1) Static
SPM SPM slot This physical resource represents the SPM. (SAHPI_ENT_IO_BLADE, Site Number of SPM) Dynamic
COM-E Slot SCM FRU
resource
This logical resource represents the COM-E
module slot carried by the ATCA-2210.

COM-E
Module
COM-E slot This physical resource represents the COM-E
module that can be installed on an ATCA-2210 .

Dynamic
RCM slot Shelf This physical resource represents the slot
occupied by the RCM.
(SAHPI_ENT_OEM_SPECIFIC, RCM Site Number) Static
RCM RCM slot This physical resource represents the RCM. (SAHPI_ENT_IO_BLADE, RCM Site Number) Dynamic
Notes:
1. The resource types listed in this table may be different depending on the applicable modules. For example, the ATCA-7220 PPM does not have
a COM-E slot or an SPM.
2. The site number used for the entity location refers to the site number associated with the physical slot listed in the AdvancedTCA address table
contained in the shelf FRU information.
3. The Lifetime column specifies when the resource is added or removed from the resource presence table (RPT). Static resources are created on
power-up and are never removed from the RPT. Dynamic resources are created when the resource is detected as present and deleted from the
RPT when the resource is detected as absent.
