This read-write integer (0-100) defines the minimum acceptable reading for temperature sensor 1, below which cpqCmcStatusTemp1 reports underMin(5). Administrators use it to catch cases where a sensor cable has come loose or an open rack door is letting in unusually cold air, both of which can indicate a monitoring fault rather than a cooling success. For instance, setting this to 40 degrees on a rack sensor lets the CMC flag an unusually low reading as suspicious rather than silently treating it as fine.
