Maintain an established Panasonic CF31 rugged-laptop environment with the customer-specific configuration represented by ST-DEPINEXEL03. This ordering code is associated with an Exelon CF31 requirement, distinguishing it from a generic notebook selection or an unspecified rugged-laptop configuration. Its value is in retaining the defined relationship between the CF31 platform and the customer-specific system requirement. The CF31 platform belongs to Panasonic's rugged mobile-computing range, where portable systems are used away from fixed desk environments. A customer-specific configuration can matter when a deployed environment depends on matching the equipment profile already associated with a particular operational requirement. The model designation identifies the CF31 platform, while the full ordering code identifies the specific configuration associated with that requirement. Use the complete ordering code when matching this system to an existing Panasonic CF31 requirement. Configuration-specific systems should not be treated as automatically interchangeable with every CF31-family unit, because the customer-specific configuration is the defining characteristic of this item. The exact hardware components, installed options, interfaces, operating system, memory, storage, display, radio configuration, and physical dimensions are not represented by the ordering code alone. Match the code to the applicable CF31 configuration requirement before selecting it for an installed environment.
