Appendix A. Firmware Checkpoint Three-Digit Codes

The three digit codes listed in Table 36 will appear to the left of the top row on the

Liquid Crystal Display (LCD) which is located on the front panel of the system. The

intended use of these codes is to assure the observer that the Firmware is

operational after power on, and before information appears on the console display.

Refer to 4.4, “Understanding the Firmware” on page 64 for more information on the

Firmware boot process.
