System-level field troubleshooting

 

 

 

 

Item

 

 

Recommended work

 

 

 

DC power level

 

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

 

 

Check that the +5 VDC value (pin of the interface connector) is 4.75 to

 

 

5.25 VDC.

 

 

Check that the +12 VDC supply (pin of the interface connector of disk

 

 

drive) is 11.4 to 12.6 VDC.

 

 

 

Electrical noise

 

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

 

 

250 mV and +12 VDC is within 250 mV.

 

 

Make sure the high frequency noise (over 20 MHz) is less than

 

 

100 mVp-p.

 

 

 

Drive selection address

 

Check that the disk drive selection address is set correctly.

 

 

 

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 disk drive.

 

 

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 disk drive. If replacing the disk drive does not

 

 

eliminate the error, the removed disk drive is probably not faulty. To

 

 

continue error analysis, refer to the hardware and software manuals

 

 

supplied with the system.

MAP3735FC, MAP3147FC specifications

Fujitsu has been a prominent player in the hard disk drive market, with its MAP3147FC and MAP3735FC models standing out in terms of performance and reliability. These drives are engineered to meet the growing demands of enterprise applications, providing robust solutions for data storage in critical environments.

The Fujitsu MAP3147FC, with a capacity of 147 GB, is optimized for high-speed data access and storage efficiency. This 3.5-inch SCSI drive operates at a rotational speed of 15,000 RPM, ensuring rapid data retrieval and minimized latency, making it ideal for applications requiring quick transaction processing. It features a 4 Gbps Fibre Channel interface, which enhances connectivity and system integration, promoting seamless communication between devices in storage area networks.

On the other hand, the MAP3735FC model offers a higher capacity of 300 GB. It shares similar specifications with its counterpart, including the 15,000 RPM speed, which guarantees top-notch performance for mission-critical applications. The MAP3735FC, like the MAP3147FC, incorporates advanced technologies such as Command Queuing, which optimizes the execution of multiple read and write commands in a queue. This feature is particularly beneficial in environments with high I/O demands, improving overall system throughput and efficiency.

Both drives utilize sophisticated error correction techniques, ensuring data integrity and reliability. They are equipped with features like S.M.A.R.T. (Self-Monitoring, Analysis, and Reporting Technology), which continuously monitors the health of the drives and helps predict potential failures, allowing for proactive maintenance and data protection.

In terms of physical characteristics, both models are designed to withstand the rigors of continuous operation. They are built with a rugged casing to protect against vibration and shock, making them suitable for use in enterprise-level servers and storage systems. Their design also allows for efficient heat dissipation, which is critical for maintaining optimal performance during extended use.
