This chapter contains information on Printed Circuit Boards (PCBs) which can be used in the
universal slots of either the Strata DK40i Expansion KSU, the Strata DK424 or DK424i cabinets.
Although the system architecture of these systems is very different, the PCBs described in this
chapter are common to both systems.
Important!
When installing these circuit boards in the DK40i Expansion KSU, you must install
them in the universal slots designated in
Chapter 2 – DK40i Configuration .
PCBs which are not installed in the universal slots of the system can be found in the installation
chapter for the system. For example, the TCOU PCB for the DK40i system appears in
Chapter 3 –
DK40i Installation . Paragraph headings identify information which is specific to a particular
system and minor exceptions are mentioned in text.
Note
Prior to PCB installation, the power supply must be tested and the ground checked.
