Autoloader self-test times
Each time the autoloader is turned on, it performs a power-on self-test (POST).
POST includes a self-test of the control electronics, initialization of the
mechanical components, and a cartridge inventory. The POST time is measured
from the time the autoloader is turned on until the autoloader indicates Ready
status. The maximum time required for POST is 65 seconds.
