AXP1440 Shelf Description
54 AXP1440 Installation and Use (6806800H23T )
The blade slots are numbered physically from 1 to 14 going left to right along the front of the
shelf. Numbers on slots 6 and 9 designate the hub slots. Each slot also has a logical slot number
that defines it for backplane connectivity. Logical slot numbers are not shown on the shelf. The
backplane functional layout is shown in the following figure.
2.6.2 E-Keying
The AXP1440 supports the shelf management infrastructure with a process called E-Keying.
E-Keying replaces the mechanical connector keying method used in earlier backplane designs.
E-Keying prevents damage to blades, prevents mis-operation, and verifies fabric compatibility.
E-Keying entries are present as FRU information in the shelf FRU and all blades present in the
shelf. The E-Keying entries describe the Base Interface, Fabric Interface, Update Channel
Interface as well as the Synchronization Clock interfaces implemented by the shelf and blades.
E-keying allows blades that support different PICMG 3 standards to be used in the same shelf.
