Update SSN-00005 for recent upgrade of Subaru/CB2F UPS

Task Major Won't Fix Won't Fix Unassigned shimono Thu, 17 Nov 2016 16:50:54 +0000 Mon, 20 Feb 2023 05:57:35 +0000 Mon, 20 Feb 2023 05:57:34 +0000 0 1 <p>Note that our standard practice is to connect dual power supply servers to each UPS, so that likelihood of downtime is minimised (e.g. if a UPS fails, or is powered-down during routine maintenance). Equipment that cannot be configured with dual power supplies should be powered from a transfer switch in the rack.</p> <p>From discussion on week of 2017/07/17 at Subaru, we agreed we need to explore current configuration and situation at Subaru including notification under Gen2 (e.g. Gen2 only receives signal from their own UPS), and we need to find Subaru-wide solution to notice power failure to instruments (OBCPs). <br/> Also we agreed we need to find solution to notice status of power transfer switch (commercial or DG) to PFS/SpS, while PFS CB2F switches are offline, especially to notice whether 2nd power outage detected at PFS SpS UPS is DG drained out or second time of commercial power outage.</p> Development Rank 0|ii00zz:
