System Requirements

The SCS-TRUMPET is a mezzanine side card, to

be fixed on top of a suitable CPU carrier board.

The pitch between carrier PCB and mezzanine

PCB is 4HP, resulting in a 8HP common front

panel for the entire assembly. Up to four

mezzanine inter-board connectors are in use,

for distribution of legacy and high speed I/O

signals from the CPU carrier to the side board.

These are referred to as HSE (SATA & USB 2.0

High Speed Expansion), EXP (Legacy Expansion),

PCIE (PCI Express® x 4), and DP (DisplayPort).

The mezzanine connectors are situated on the

bottom side of the SCS-TRUMPET, facing

towards their mating CPU card connectors.

The SCS-TRUMPET also is a carrier board itself,

which can accommodate two M.2 SATA SSD

storage modules, or a 2.5-inch SATA drive, and

a front panel I/O expansion card as an option.

It is recommended to use a CompactPCI® Serial

backplane which provides the CPU card system

slot on the right edge, in order to prevent loss

of a peripheral slot (the SCS-TRUMPET is then

positioned out of the backplane shape). Use of

the rear I/O option requires either a custom

specific rear transition module in addition, or a

secondary CPCI Serial backplane, for front

installed SATA or USB based CPCI Serial cards.
