Publication No. SBC329-HRM/1
Functional Description 79
5.23 Front Panel
5.23.1
Air-cooled Versions (Build Levels 1 to 3)
In build levels 1 to 3, the SBC329
supports the VITA 48.1 1” pitch form factor.

XMC Slot
The SBC329 front panel has provision for front I/O from the XMC site. If an XMC has
not been ordered as part of an assembly with the SBC329, then Abaco will fit a
blanking plate in the slot for EMC protection.
If you are fitting a non-Abaco XMC, it must comply with the appropriate standard for
air-cooled XMCs to ensure that it mates correctly with the SBC329 mechanics. Abaco
XMCs comply with this standard.
If you are fitting a XMC with a bezel yourself, before fitting the module, remove the
blanking plate from the sl
ot. The XMC’s bezel should fill the slot and may provide
front panel connection to the module. Abaco XMCs are delivered with a full kit of
parts for mounting.
5.23.2
Conduction-cooled Versions (Build Levels 4 and 5)
In build levels 4 and 5, the SBC329 supports the VITA48.2 type 1 (with 2LM covers)
and type 2 (without 2LM covers) 0.85
” pitch form factors.

XMC Slot
There is no access to front I/O from XMCs in a conduction-cooled environment.
If you are fitting a non-Abaco XMC, it must comply with the appropriate standard for
rugged, conduction-cooled XMCs to ensure that it mates correctly with the SBC329
mechanics. Abaco XMCs comply with this standard.
