Printed Circuit Boards

This chapter provides procedures for the installation of
Strata DK280 system printed circuit boards (PCBs). It
includes installation instructions, optional configuration
information, wiring, and programming considerations
for each PCB.
Install PCBs only after installing the base cabinet and,
if applicable, expansion cabinets per Chapter 3-
Cabinet Installation.
Note:
Be sure the power supply has been tested,
and the ground has been checked.
PCB model numbers end with the letter "A," but in this

document the is deleted because
Examples: PCB model number PDKUlA is written
"PDKU," RSTU2A is written "RSTU2."
4.1 Inspection, Packaging and
Storage
4.1.1 Inspection
When the system is received, examine all packages
carefully and note any visible damage. If any damage
is found, do not open the packages. Contact the

claims.
After unpacking (and before installing), check the
system against the packing list and inspect all
equipment for damage. If equipment is missing or

4.2.1 PCB Installation Considerations

The base cabinet has eight slots. The first two slots,
labeled "R11" and "RCTU" are reserved for the
common control unit and future feature upgrades. The
remaining six slots (labeled "Sll," "S12," "S13," "S14,"
any of the station, line, and option interface PCBs
compatible with the DK280 systems. (If needed, RSlU
must be installed in slot 11
The expansion cabinets Have six universal slots,
