Installation Requirements
The optical disk drive can be mounted in a 120 mm (5 inch) device bay of the PC chassis using either a metal frame or a plastic (nonconductive material) frame.
If a plastic frame is used, the personal computer's FG and the optical disk drive's FG are not shorted. Consequently, the static electricity tolerance is inferior to that realized when a metal frame is used. Fujitsu recommends using a metal frame. In particular, a metal frame must be used especially when high static electricity tolerance is required.
3.3 Power Supply Requirements
(1) Allowable input voltage and current
The DC power supply input voltage must satisfy the requirements described in Section 2.1.3, "Environmental and power requirements" when measured at the power supply connector pin (receiving end) of the optical disk drive (For other requirements, see items (4) and (5) below).
(2) Current waveform (reference)
Figure 3.8 shows the current waveform while a disk is inserted.
Figure 3.8 MCM3130SS current waveform (+5 VDC)
(3)Power on/off sequence
a)In a system which uses the terminating resistor power supply signal (TERMPWR) of the SCSI bus, the requirements for +5 VDC given in Figure 3.9 must be satisfied between the drive and at least one of the SCSI devices supplying power to that signal.
