From what I'm understanding: "For device selection during future expansion. When one HDD is used, please set the switch to DEVICE0".

The drive only spins up when the DEV9 and ATA interfaces are initialized, like any newer Playstation 2 console. The enclosure's fan spins up when the DEV9 interface is brought up, and the disk only spins up when the ATA interface is initialized.
However, pressing the RESET button will cause the console to reset immediately, unlike newer consoles.
Not to mention that the boot ROMs of these older consoles do not contain any code for supporting the HDD unit at all. Not even the SCPH-18000, since the newer boot ROM of that console only supports the CXD9611 EXPANSION BAY ().
