Solenoid Drive Lock
The factory installed solenoid option prevents premature removal of the carrier and drive
unit until the target drive has fully spun down. For most disk drives, this period of time
can range from 15-40 seconds, depending on the type of drive being used (e.g. Seagate
Barracuda drives require up to 45 seconds). Refer to the drive manufacturer's documen-
tation for specific drive information.
The solenoid lock is controlled by a timing switch located on the side of the receiving
frame. Refer to the previous section "Carrier Installation", for information describing the
readjustment of the timer setting.
The solenoid option provides an extra step in drive protection by preventing the removal
and movement of the drive until the drive motor has fully stopped.
