Power-up and Boot Procedures
The Remote Annex 2000 has two modes of operation: normal and test.
Normal mode is the standard operational mode. Test mode provides
access to the ROM Monitor commands. Pressing the button
on the front panel within 3 seconds of powering-up or a system reset
puts the Remote Annex 2000 into test mode. When the Remote Annex
2000 is in test mode, the button’s LED lights.
Figure 1-5 on
page 1-6 illustrates the Remote Annex 2000’s front panel.
During the power-up and boot sequence, the Remote Annex 2000 runs
a set of diagnostics. The system LEDs display the diagnostics’ status;
the status LEDs light in sequence. The Remote Annex 2000 stops when
it detects one of four error conditions (see
Table 4-2 or Table 4-4). The
flashing pattern of the system LEDs identifies the error condition.
Normal Mode Diagnostics
Following power-up or reset, the Remote Annex 2000 enters normal
mode. The following subsections describe both the possible error and
error-free conditions that can occur during power-up and booting in
normal mode.
