On day 357 (12/23/99) at approx. 2300z the UPS supporting the ACE MOR experienced a glitch which caused the MOR system to power cycle. MAR system was not impacted. SOHO personnel contacted ACE of this occurrence during ACE off hours. FOT came in after being contacted to check string status. The MOR FEP and Workstation 2 were impacted by glitch.

Anomaly report AR G99-0065 associated with DR# G05617 was generated as a result of the late AOS. On 12/28/99 station D54 had a delayed AOS due to link controller setup problems - No impact. Executed OCR SC-012 to load TT bin to poke C&DHs in case of communication problems for Y2K contingency. The poke commands will execute at 00-004-17:00:00 on active and inactive C&DH's which will provide another 96 hours until a reset without ground contact. /= G_END_DAY ! @f@ SC_ W - change downlink format to bin_dump & dump Autonomy & Time Tag bins from Active C&DH calls c_aut_tt_dump_act ! `f@ SC! - perform GRI / COMPARE ( ! f@ SA6 . # OF AUTONOMY MISCOMPARES: ___________________ ( ! f@ 6 9 S u b U 7 8 9 D !
