Internal Assemblies — Front Chassis 4: Repair

Processor PCA
The Processor PCA contains the SOM PCA that stores the device software and configuration data.
When you install a new Processor PCA, you must also:
• Enter the device’s serial number and enable options using the Service Mode menus.
• Install the most recent software in the appropriate language using the Software Support tool. See
Table 39 on page 176 for part numbers.
• Give the user the README document that contains instructions for downloading the most recent
HeartStart XL+ Instructions for Use from the Philips’ Documentation and Download web site
(
http://www.philips.com/ProductDocs).
CAUTION: Never touch the Processor PCA surface with your fingers, always use gloves.
Keep the new Processor PCA in an antistatic pouch until ready to install.
Do not attempt to reuse the old SOM PCA with the new Processor PCA.
Removing the Processor PCA involves disconnecting many cables and removing many screws. Note that
the edges of the metal chassis may be sharp. Take care not to cut yourself or shear the wires.
