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 documentation for specific drive
information.
The solenoid lock is controlled by a timing switch located on the side of the receiving frame.
Refer to section "Adjusting the Spin Down/Up Timer" for further information.
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.
