DSM16+ and DSM 32+ double density switch settings (new 3.0 system)
The following table shows the switch settings for DSM-plus modules deployed as double density
on a new 3.0 system.
Companion has not be included in this table because you cannot use double density modules to
deploy Companion.
Note: DSM modules deployed prior to 3.0 are all single density and cannot be set to
double density, but they can still be used on new 3.0 systems. The DSM 16+ and DSM32+
modules can be set to either density.
