Maintenance Analysis Procedures (MAPs)
Step 8(from Step 7)
1. Set the power switch on the system unit to Off.
2. Disconnect and remove the front disk drive from the frame.
3. Install the disk drive frame in the system planar.
4. For Models 320, 32E, and 32H with SCSI-attached rear disk drive, connect the data
cable to the disk drive and the SCSI adapter on the system planar.
5. Set the power switch on the system unit to On. Wait 10 seconds before answering the
following question.
Did the power-on light come on and stay on?
NO One of the remaining FRUs is defective.
To test each FRU, exchange the FRUs in the following order:
1. Rear disk Drive
2. Data cable (Models 320, 32E, and 32H with SCSI-attached disk drives)
3. Riser card (Models 320, 32E, and 32H with bus-attached disk drives)
4. SCSI bus extender card (Models 340, 34H, 350, 355, 360/36T, 365,
370/37T ,375, 380, 390, 39H, and 397)
5. System planar (Models 340, 34H, 350, 355, 360/36T, 365, 370/37T,
375, 380, 390, 39H, 397 and models 320, 32E, and 32H with
bus-attached disk drives)
If the symptom did not change and all the FRUs have been exchanged go
to Step 11.
YES Exchange the front disk drive. Go to “Map 0410: Repair Checkout” in the
