Figure 4.12 Power on/off sequence (1)
c) In a system which does not use the terminating resistor power supply signal (TERMPWR) on
the SCSI bus, the requirements for +5 VDC given in Figure 4.13 must be satisfied between the
IDD and the SCSI device with the terminating resistor circuit.
Figure 4.13 Power on/off sequence (2)
d) Between the IDD and other SCSI devices on the SCSI bus, the +5 VDC power on/off sequence
is as follows:
•
In a system with its all SCSI devices designed to prevent noise from leaking to the SCSI
bus when power is turned on or off, the power sequence does not matter if the
requirement in b) or c) is satisfied.
•
In a system containing an SCSI device which is not designed to prevent noise from
leaking to the SCSI bus, the requirement given in Figure 4.14 must be satisfied between
that SCSI device and the IDD.
