For example, if the setting for switches 1 through 3 are "Down." the device ID
addresses for the drive slots 1 - 12 would be 0 - 11 respectively.
NOTE:
If a hard address ID conflict occurs during Fibre Channel loop
initialization, the Fibre Channel protocol will dynamically set the drive
IDs. This could cause problems with some software products.
Switches 4, 5, and 6 are not used.
Spin-Up Settings
