External Storage Devices
The AT8001 supports external storage device either through the fibre chanel interface (front SFP
module or via a fabric interface switch) or through SATA connectors on the RTM. Note that SATA is
only available on the RTM with some option of the AT8001.

Power Supply
The AT8001 expects two –48V feeds as per PICMG3.0R1.0. The AT8001 is fully working over a range
of –39.5V to –72V as required by the specification.
4.1.5
Connector Keying
Mechanical keying in ATCA system exists for the main backplane and for RTM. Currently only one key
is defined for ATCA front board: A1/K1 key value is 11.
RTM key is defined by front board manufacturer. Currently, Kontron use the A2/K2 value of 11 for
it's front CPU board and matching RTM.
Specific connectivity either with the backplane or the RTM may vary and electronic keying (E-
Keying) allow the IPMC (intelligent platform management controller) to prevent connection of
incompatible components.
