The SCP/DCP-122 employs 110-pin connectors for the J1 and J2 interfaces. Proper mating
of these connectors with the CompactPCI backplane requires a significant amount of
insertion force. Use extra care when aligning and inserting your SCP/DCP-122 into your
chassis to ensure that a secure mechanical and electrical connection is made between the
card and the backplane mating connectors.

OCATION
If you want your SCP/DCP-122 to function as the system controller, insert your SCP/DCP-
122 in the system slot. The system slot is typically the leftmost or rightmost slot on the
backplane and is denoted by a “
∆
" symbol.
The system controller provides the following to the CompactPCI bus:
• arbitration
• clocks
• terminations
• system reset
• PCI configuration
If the SCP/DCP-122 is inserted into any of the peripheral slots, marked with a circle, it
functions as a peripheral card. A peripheral card requires a system controller to provide the
above functions.
Warning
This card uses components that are sensitive to electrostatic discharges. It must be kept in
its conductive package until just before the installation begins. Remove the card from its
protective package only at a grounded workstation while wearing an approved grounding
wrist strap. Avoid touching any metal contacts on the card; static discharge can damage
integrated circuits.
Turn the power off before inserting or removing cards from the chassis. Failure to do so
could damage the card circuitry or cause personal injury.
Note
Either end slot on the backplane may be configured as the System Slot. Refer to the chassis
vendor’s documentation to determine which slot is the System Slot.
