FAMIS 31133

On Friday, h1psl0 was rebooted as part of updates to its timing card firmware and RCG (see alog89859), which unlocked the PMC briefly and left the ISS off (on purpose, the autolocker is turned off in SDF so that it can be turned on later once the PMC thermalizes). It looks like the PMC (as usual) relocked at a slightly different temperature; it doesn't appear to have much effect this time on the transmitted power, but the reflected power is very slightly lower. I've turned the ISS autolocker back on.
