Table 6.2 System-level field troubleshooting Item Recommended work DC power cable Check that the power cable is correctly connected to the disk drive and power supply unit. DC power level Check that the DC voltage is within the specified range (±5%). Check that +5V DC supply is from 4.75 to 5.25V DC. For NC model, check the voltage between pin 36 and 76 of the SCSI connector. For NP model, check the voltage between pin 3 and 4 of the power connector. Check that +12V DC supply is from 11.4 to 12.6V DC. For NC model, check the voltage between pin 1 and 2 of the SCSI connector. For NP model, check the voltage between pin 1 and 2 of the power connector. Electrical noise Make sure the maximum ripple peak-to-peak value of +5V DC is within 250 mV and +12V DC is within 250 mV. Make sure the high frequency noise (over 20 MHz) is less than 100 mVp-p. Interface cable connection Check that the SCSI interface cable is correctly connected between the disk drive and controller. Terminating resistors For a daisy chain connection, check the terminating resistor on the last disk drive only. For a star-burst connection, check that the terminating resistor is correctly mounted on all disk drives. Drive selection address Check that the disk SCSI ID is set correctly. Plug setup Check that the jumpers on the PCBA are set so that the disk drive and host computer operate normally. See Section 5.3. System cables Check that all system cables are connected correctly. System diagnostic test When possible, execute the system level diagnostic routine as explained in the host computer manual. This gives a detailed report of a possible fault. Intermittent or nonfatal errors Check the AC voltage from the power supply. Check the DC voltage level at the power connector for the HDD. If the AC voltage level is abnormal or there is a lot of electrical noise, notify the user of the error. If the DC voltage level is unstable, replace the power supply unit. If possible, replace the HDD. If replacing the HDD does not eliminate the error, the removed HDD is probably not faulty.

Recommended work

DC power cable

Check that the power cable is correctly connected to the disk drive and

power supply unit.

Check that the DC voltage is within the specified range (±5%).

Check that +5V DC supply is from 4.75 to 5.25V DC.

For NC model, check the voltage between pin 36 and 76 of the SCSI

connector.

For NP model, check the voltage between pin 3 and 4 of the power

connector.

DC power level

Check that +12V DC supply is from 11.4 to 12.6V DC.

For NC model, check the voltage between pin 1 and 2 of the SCSI

connector.

For NP model, check the voltage between pin 1 and 2 of the power

connector.

Make sure the maximum ripple peak-to-peak value of +5V DC is within

250 mV and +12V DC is within 250 mV.

Electrical noise

Make sure the high frequency noise (over 20 MHz) is less than 100 mVp-p.

Interface cable connection

Check that the SCSI interface cable is correctly connected between the

disk drive and controller.

Terminating resistors

For a daisy chain connection, check the terminating resistor on the last

disk drive only.

For a star-burst connection, check that the terminating

resistor is correctly mounted on all disk drives.

Drive selection address

Check that the disk SCSI ID is set correctly.

Plug setup

Check that the jumpers on the PCBA are set so that the disk drive and host

computer operate normally.

See Section 5.3.

System cables

Check that all system cables are connected correctly.

System diagnostic test

When possible, execute the system level diagnostic routine as explained in

the host computer manual.

This gives a detailed report of a possible fault.

Check the AC voltage from the power supply.

Check the DC voltage level

at the power connector for the HDD.

If the AC voltage level is abnormal or there is a lot of electrical noise,

notify the user of the error.

If the DC voltage level is unstable, replace the power supply unit.

Intermittent or nonfatal errors

If possible, replace the HDD.

If replacing the HDD does not eliminate the

error, the removed HDD is probably not faulty.

To continue error

analysis, refer to the hardware and software manuals supplied with the

system.
