A.1 Introduction
Error messages are posted in the Host Interface Memory’s message area (0040h) and can be
displayed using one of the status applications, such as DNSTAT, provided with the card.
For details on the shared Host Interface Memory layout, refer to the Firmware Reference Guide.
A.2 FamilyID Messages
If FamilyID reads anything other than 0x40, the card has not been found. Check for
memory and I/O conflicts. If you continue to experience difficulties, refer to Section 4.4,
General Troubleshooting.
A.3 Fatal Hardware Self-Test Flash Codes
Fatal failures during startup are accompanied by an 8-bit fault code, flashed on the Health Led.
The fault code will be output MSB first, with a 1 (one) bit shown as a green LED, and a zero (0)
bit shown as a red LED. This will occur for a period of 900ms, followed by 100ms of off time.
The LSB will be followed by an additional 1000ms of off time, after which the sequence will
repeat.
The following table describes each possible fault code.
