1.6 Safety Precautions
Follow these simple precautions to protect yourself from harm and the products from
damage.
! To avoid electric shock, always disconnect the power from your CompactPCI
chassis before you work on it. Don’t touch any components on the CPU board or
other boards while the CompactPCI chassis is powered.
! Disconnect power before making any configuration changes. The sudden rush
of power as you connect a jumper or install a board may damage sensitive elec-
tronic components.
! Always ground yourself to remove any static charge before you touch your CPU
board. Be particularly careful not to touch the chip connectors.
! Modern integrated electronic devices, especially CPUs and memory chips, are
extremely sensitive to static electric discharges and fields. Keep the board in its
antistatic packaging when it is not installed in the chassis, and place it on a
static dissipative mat when you are working with it. Wear a grounding wrist strap
for continuous protection.
1.7 Installing CompactFlash in the MIC-3392MILC
Model
The CF socket (CN10) for the MIC-3392MILC model is beneath the conduction-
cooled plate, therefore installing a CF card on this particular model requires removing
the conduction-cooled plate from the PCB first. The following steps illustrate the
removal of the plate and the installation of the CF card.
1.7.1 Wedge Locks Removal
Each wedge lock is secured to the conduction-cooled plate by two M2 x .40 screws,
which can be accessed on the PCB guide base located on the secondary side of the
PCB. There are two wedge locks, two PCB guide bases, and four M2 x .40 screws on
the MIC-3392MILC. See Figures 1.3 and 1.4 for illustration.
