604 Voltage Check
The system supplies DC voltage to the diskette drive through connector PS. PS connects to the drive control
card through the I/O connector pins (I/O CP)
II.
(Measure voltages at test points on diskette drive.) In
World Trade countries, remove the ESD protection shield before verifying the voltages. Use a multimeter to
verify the voltages.
If the voltages are missing or not correct, go to "435 DC Voltage Distribution" on page 4-11.
If the voltages are correct, exchange the A1D2 card or the diskette drive ("606 Diskette Drive Removal").

3. Remove the four mounting screws (two on each side) from the diskette drive.
4. Slide the diskette drive slightly forward to permit access to the cables.
5. Disconnect the PS power plug and the signal cable.
6. Remove the ESD protection shield (World Trade only).
7. Remove the diskette drive by sliding the unit towards you until it is out of the 5363 frame.
