The eight-slot backplane features a single DIN M power slot and a single fabric slot; the 15-slot version has double DIN M power slots and twin fabric slots.
The 21-slot unit has twin fabric slots and, because it is a full-width 19in unit, power-on is via power bugs.
On all widths the system slot can be configured as a node slot if required.
Updated StealthBridge rear plug-up bridges are fitted to the 15- and 21-slot units; they support the latest processor cards conforming to PICMG 2.0 Rev.

CompactPCI/PSB is a star topology: in a 2.16-enabled system, boards are defined as nodes (equivalent to LAN workstations) or fabrics (equivalent to LAN hubs).
It significantly improves performance, scalability and reliability of CompactPCI while preserving its mechanical interchangeability, redundant power options, hot-swap attributes and H.110 capabilities.
The PSB specification supports scaleable bit rates of 10/100/1000Mbit/s per slot, giving the choice between low cost or high performance; hot swap is provided within the CompactPCI bus and high availability is enabled through redundant Ethernet switching on two independent Ethernet networks embedded in the CompactPCI backplane on P3.
Node cards, operating as standalone "systems in a slot", interface with each other through the fabric slots using a network stack such as TCP/IP.
The fabric slots in PSB systems can interface with external networks by using either fibre or copper network media.
