Final Configuration / Exit Criteria:
1.
The SIU and EPUs are running in application mode and providing
secondary boot telemetry.
2.
SIU control of the LTC is enabled and observed to be functioning
properly.
3.
The GASU and PDU specified in the selected redundancy
configuration are on and operating.
4.
All 16 towers are powered.
5.
All 12 ACD Free boards are powered.
6.
All ACD, CAL, and TKR HVBS are at their operational levels.
7.
The power consumption test passed.
8.
The muon run passed.
Purpose:
The L-OBS-00x procedure powers on the LAT from a fully off state, with
support from the Spacecraft, and places it into one of the nine redundancy
configurations.
Description:
At the start of L-OBS-00x the Spacecraft energizes the SIU, VCHP Heater,
and Unregulated Heater feeds consistent with the redundancy configuration
shown in Table 1 below. LAT then performs secondary boot of the SIU and
enables LTC. Once the SIU is in application mode, the Spacecraft
energizes the DAQ feed. LAT then powers the PDU and GASU, powers
and executes secondary boot on the two EPUs, configures all 16 towers, the
ACD FREE boards, and sets the Detector HVBSs to operational levels. A
power consumption test and short muon run are performed to verify the
LAT is in a valid configuration. The Spacecraft dumps the SSR following
the LAT muon run so that the results can be verified.

Constraints:
1.
All telemetry check and command execution failures must be
coordinated with Systems Engineering before proceeding.
2.
For Thermal Vacuum testing, all units must be within operational limits
prior to applying power to that unit.
Reference:
3.
Only one VCHP feed may be enabled when an SIU is powered on.

Initial Configuration / Entrance Criteria:
Parent Procedure:
1.
LICOS can send commands to AstroRT and receive science and
telemetry data from Spacecraft Integration & Test (SCIT) console.
