This section illustrates how some of the features of the instrument may be used in combination to perform various procedures. such as restarting the instrument after a power-off. The actual procedures used in-flight will probably be different, due to system requirements beyond that of the software, or due to experience developed as the system is used.
The purpose of the on-orbit check-out is to verify that none of the hardware broke during launch and on-orbit insertion.
TBD - Talk to Bob and get a better picture of what should go here. Maybe variation of short-form, long-form?
Pre-Power On check of passive analog telemetry and S/C conditions
DPA Side-A Power On
DPA Voltage, Current and Thermal Check
Select BEP A
Cold Boot BEP (prior to cold boot after DEA power-on. If a problem arose in commanding DEA after latter cold boot, ya might not know if it was the cold-boot, or the DEA interface which killed ya).
Some form of Command Check (e.g. send a "no-op" software command and check that ya gets an echo).
ROM Dump and Compare (does a good telemetry check)
System Configuration Dump (verify temperature set-points prior to DEA power-on, etc.)
FEP Power On Check
DPA Voltage, Current, and Thermal Check
FEP I-cache Read Check (more to test FEP aliveness than anything else)
DEA Side-A Power On
DPA/DEA Voltage, Current and Thermal Check
Cold-Boot BEP (to load System Configuration Info into newly powered DEA board)
Start interface board DEA Housekeeping
Check DEA housekeeping info (including relay states)
