EPH temp 90.56 degF NOTES/ISSUES/PROBLEMS From the 9am status meeting: Two supports in the past 24 hours, one callup in progress. One load segment was uplinked, on-board loads good until 086:05:20. Three dumps, all data current. The 2315 comm tonight will be extended about one hour, and the 0750 comm deleted. The MAR2805A products came out this morning, for a load review today at 2pm. Next Monday and Tuesday will be a safemode recovery simulation. Rino has emailed a briefing package. We are proceeding with the UPS battery replacement this afternoon at 1pm. At noon, the databases will be shut down to protect them against a power outage while there is no UPS backup. We expect UPS work to be completed in time for the pass at 1735 EST this afternoon, but in a worst case we can miss this pass, fail over to SSR B, and no data will be lost.
