System Overview
AXP 1410 Installation and Use (6806800H70L) 53
1.1.5.1 Base Interface
The base hub slots (physical slots 6 and 9) have four pairs of 1000Base-T signals to node slots
which form the dual star topology fabric. Each of the node slots support two base channel
interface signals that connect to each hub slot. In turn, the channel 1 base interface of each hub
slot is connected to the SAM. Each of the hub slots support a total of 14 base channels. The hub
slots require connectors P23 and P24. The base node slots require only connector P23.
1.1.5.2 Fabric Interface
The fabric interface supports point-to-point connections between AdvancedTCA blades. In the
AXP 1410, these fabric connections are configured in a dual star topology that runs back to the
hub slots. The AXP 1410 system has PICMG 3.1 Option 9 channel slots. These channels are
aggregated at the hub slots into the dual-star topology. In this configuration, all node slots
support one fabric channel to each of the two hub slots. The fabric channels are located on
connector P20 of the node slots, and connectors P20, P21, P22, and P23 of the hub slots.
The implementation of the interface is indicated by the level of PICMG compliance a blade or
hub is designed to. The AXP 1410 supports the PICMG 3.1 fabric standard to allow for several
configuration options that can provide greater bandwidth to certain slots in the shelf. The
fabric interface switch supports: PICMG 3.1 Option 9 (10Gbps).
A PICMG 3.1 compliant hub provides 10GBASE-BX4 to the fabric interface of a PICMG 3.1
compliant blade.
1.1.6 Rear Transition Modules
The AdvancedTCA blades can be connected to Rear Transition Modules (RTM) to provide easy
access to I/O signals through the zone 3 connector defined by the AdvancedTCA specification.
The blade slots are numbered physically from 1 to 14 going left to right along the front of
the shelf. Each slot also has a "logical" slot number that defines it for backplane connectivity;
logical slot numbers are not shown on the shelf. Please note that the slots will be referred to
by their physical slot location.
