Using the Embedded Configuration

In addition to the four EHX configurations that can be stored on the card, the CPU card also includes an embedded configuration. The embedded configuration is designed for fast fault checking following a system upgrade or field install (for example, checking hardware connections with user panels and interface cards).

Note: The embedded configuration may also be used as a back-up configuration, in the very rare event that a system error renders the other configurations unusable.

To activate the embedded configuration:

  1. On the front of the CPU card, press and hold the CONFIG and the ENG buttons.

  2. Simultaneously, reset the CPU card by pressing and holding the CPU card’s lower RESET button (the Full reset button).

    Note: A tool, such as a pin, is used to press and hold the RESET button.

  1. Continue holding the CONFIG, ENG and RESET buttons until the CPU card’s dot matrix display displays 0. It may take 1 - 2 seconds before 0 is displayed.

    The embedded configuration has now been activated.

To deactivate the embedded configuration, perform a CPU card reset.

The configuration (1, 2, 3 or 4) that was previously active on the CPU card replaces the embedded configuration as the active configuration.
