10.1.1 Option Card Diagnostic Errors
Option cards are detected by the
820i
at power-up. If the current indicator configuration requires an option card but that card is
not detected at power-up, an error similar to the following is displayed:
HARDWARE CRITICAL TO PROPER OPERATION
WITH CURRENT CONFIGURATION
CANNOT BE FOUND
INSTALL HARDWARE OR RECONFIGURE
To recover from this error you can do the following:
• If the option is required, ensure that the card is properly seated in its slot and cycle the power. If the card is still not
recognized, replace the card.
• Enter setup mode and reconfigure to eliminate the requirement for the option.
• Go to the VERSION menu and use the
Reset Config
softkey (or RESETCONFIGURATION command) to perform a
configuration reset. Configuration reset returns all configuration values to their factory defaults.
See
below, for information about using the HARDWARE serial command to verify that installed cards are
recognized.
10.1.2 Using the HARDWARE Command
The HARDWARE serial command can be issued to verify that all installed cards are recognized by the system. The
HARDWARE command returns a string of card type codes. The first digit represents the single- or dual-A/D of the
820i
; the
second digit represents the card, if any, installed in the expansion slot:
HARDWARE=3,4
Table 10-2 lists the card codes returned by the HARDWARE command.
If an installed card is not recognized (HARDWARE command returns a code of
0
for that slot), ensure that the card is seated
properly. Reinstall the card, if necessary, then cycle the indicator power to read the configuration again.
