COMMENT ON B98 98-SBB4, 98-SBB4A Installation
Shutdown of the SB-B4A will affect PSS with response similar to what was observed yesterday.
The PSS is backed up by UPS but runtime is less than an hour. If power interruption is short, the PSS may ride it through. If not, SSG will respond to the state changes to secure and later restore BSY and Halls B & C PSS segments.
