Power on/off sequence
a) The order of the power on/off sequence of +5V DC and +12V DC, supplied to the HDD, does
not matter.
b) In a system which uses the terminating resistor power supply signal (TERMPWR) on the
SCSI bus, the requirements for +5V DC given in Figure 4.9 must be satisfied between the
HDD and at least one of the SCSI devices supplying power to that signal.
