Update Channel Interface

The update channel interface consists of 10 differential pairs on the P20 connector. The
physical layer and protocol used on this interface is application specific.

Backplane and Component Connectivity

The blade connectivity on the AXP640 backplane is divided among three zones, each with the
following characteristics:
Zone 1 provides redundant, radial IPMI to all blade slots and redundant -48 VDC to all blade
slots
Zone 2, the data transport interface, provides the dual star configuration for the base
interface, dual star configuration for the fabric interface, update channel routing for all
blade slots, and three redundant, bussed telecom clock signals to all blade slots
Zone 3 provides the PICMG 3.0 defined open area that is application specific
Rear Transition Modules connect directly with the connectors on the front-side blade and do
not make the connection through the backplane.
