The first option is a pair of mounting brackets for use on the front of the
chassis. The second option is a rear rack mount kit. The rear rack mount kit
differs from the front kit to allow for easier installation into the rack.

Slot Blockers
Optional slot blocker kits are available from National Instruments for
improved thermal performance when all slots are not used.
PXI-1042 Series Backplane Overview
Interoperability with CompactPCI
The PXI-1042 Series backplane is interoperable with PXI-compatible
products and standard CompactPCI products. This is an important feature,
because some PXI systems may require components that do not implement
PXI-specific features. For example, you may want to use a standard
CompactPCI network interface card in a PXI chassis.
The signals on the backplane P1 connector meet the requirements of the
CompactPCI specification for both the peripheral and system modules.
The PXI-specific signals are on the P2 connector and are found only on the
signal lines reserved or not used in the CompactPCI 64-bit specification.
Therefore, all modules that meet the requirements of the CompactPCI
64-bit specification will function in the PXI-1042 Series.
System Controller Slot
The system controller slot is Slot 1 of the chassis as defined by the PXI
specification. It has three controller expansion slots for system controller
modules that are wider than one slot. As defined in the PXI specification,
these slots allow the controller to expand to the left to prevent the controller
from using peripheral slots.
