MD21 Controller Setup
5.3.1.3 Disable Drive Spinup (SWl-6)
Switch SWl-6 indicates whether or not the MD21 Controller
automatically spins up the drive during controller power up. When
this switch is set to ON (closed), the controller does not spin up
the drives during power up. When this switch is set to OFF (open),
the controller automatically spins up the drives during power up.
The factory setting is OFF, as shown in Figure 5-3.

NOTE
The disk drive must be configured to only
spin up upon a command from the
controller or this switch will have no
effect.
5.3.1.4 Disable Soft Error Reporting (SWl-7)
Switch SWl-7 indicates whether or not the MD21 Controller reports
soft errors that occur during MD21 operations. When switch SWl-7
is left in the OFF (open) position, the MD21 Controller reports
soft errors. Setting switch SWl-7 to ON (closed) prevents the MD21
Controller from reporting soft errors. Normally, switch SWl-7 is
set to OFF, as shown in Figure 5-4.
