6. Anomalies report:
====================
Quote MOC, Anomaly reports:
---------------------------
On 2012-05-30 (DOY 151) at 22:34Z during the post-eclipse reconfiguration of JEM-X2, another DFEE anomaly occurred.
Following the execution of LECLXT01 ED, the symptoms were as follows:
the JEM-X2 DFEE state (TM parameter L5022) remained MEMORY, instead of SAFE, the Active Shutdown Level (TM parameter L5381)
remained ECLIPSE instead of RAD. BELTS, the DFEE CPU speed (TM parameter L5583) remained at 8 MHz WAIT instead of 16MHz.
The recovery was initiated immediately, and completed before the next scheduled activity (LEACAL01).
A DFEE power cycle was performed according to CRP_JEM2_5011, consisting of:
- FCP_JEM2_9010 JEMX2 DFEE SWITCH OFF
- FCP_JEM2_0021 JEMX2 DFEE ACTIVATION
At 22:55:30 JEMX-2 was restored to the nominal state.
