FFD 3.5" SCSI Flash Disk User Manual 1 General This manual provides you with the information you need to properly install your new FFD 3.5" SCSI Flash drive. M-Systems recommends that only properly qualified and trained personnel install the drive. The following sections contain information about handling, mounting considerations, address and configuration setups, cabling and connectors, and how to obtain technical assistance and service.
FFD 3.5" SCSI Flash Disk User Manual 4 Handling Instructions You can prolong the life of your FFD, increase its reliability and prevent unnecessary damage by following the instructions listed below. Failure to follow any of these instructions may void your warranty. • Always take all proper ESD precautions, including personnel and equipment grounding. • Always operate the FFD within the environmental specifications. • Always use a grounded wrist strap when handling the FFD.
FFD 3.5" SCSI Flash Disk User Manual 5 Installation 5.1 System Requirements In order to install the FFD in your system, ensure that you have the following items: • System mounting hardware • 4-pin power cable • 50-pin ribbon SCSI cable • SCSI host adapter • Appropriate device driver for your operating system and SCSI host adapter 5.2 FFD 3.

Only the devices connected at either end supply terminations.
FFD 3.5" SCSI Flash Disk User Manual 5.2.3 Termination Power (TRMPWR) Termination power must be supplied by at least one device on the SCSI bus; it is normally supplied by the host adapter. However, if you are unsure whether TRMPWR is available in your system, you can configure the FFD to supply TRMPWR. Note that several devices can supply TRMPWR without affecting overall system performance or causing damage to the drive (or any other device on the bus).
FFD 3.5" SCSI Flash Disk User Manual 5.3 FFD 3.5" SCSI Flash Disk Drive Installation The FFD can be installed in any mounting position in the system. Unlike rotating disks that have an axis of rotation, the FFD is not susceptible to damage due to orientation. Note: It is not necessary to perform a low-level format on the FFD. The drive is shipped low-level formatted and ready for use. 5.3.

FFD 3.5" SCSI Flash Disk User Manual 5.3.2 Using the FFD on a DOS-Based Platform After physically installing the FFD, it must be installed as a disk drive under DOS. Run the DOS commands listed below and follow the instructions displayed for each command. For more information regarding the DOS commands, refer to your DOS manual. To install the FFD as a disk drive under DOS: 1. Run the DOS FDISK program to partition the FFD.
FFD 3.5" SCSI Flash Disk User Manual In order to proceed with the installation, you must have Supervisor privileges on your UNIX system. If you do not have these privileges, contact your system administrator. To install the FFD as a drive under UNIX: 1. Run the UNIX format utility and follow the displayed instructions. 2. Select the FFD from the list of drives. 3. Define a new drive and manually enter the drive parameters using the type option.
FFD 3.5" SCSI Flash Disk User Manual 6 Drive Parameters Most SCSI device drivers can automatically detect the total number of sectors on the FFD, using the READ CAPACITY command, and configure them accordingly. However, some older device drivers must obtain the drive geometry parameters manually. The physical drive parameters are only a convention, and have no effect on how data is stored on the FFD.

Table 6 Describes the LED color codes and status definitions. Figure 4: Front Panel LED Indicators Table 6: LED Status Description Status LED Color Indicator Description Green Indicates that power is applied to the disk.
FFD 3.5" SCSI Flash Disk User Manual 8 Troubleshooting 8.1 Built-In Self Test The FFD performs a self-test during power up. If the test fails, the green LED flashes at a rate of 1 Hz. If you encounter this problem, please contact your dealer or technical support. 8.2 Common Problems The following sections describe common problems and their causes. 8.2.1 Installing Your SCSI Host Adapter A SCSI host adapter is basically a standard PC board, regardless of the bus system used.
FFD 3.5" SCSI Flash Disk User Manual 6. Attach the SCSI cable to the host adapter and to the last device. Do not forget the device’s power connector. 7. Power ON the PC and verify that the host adapter recognizes the SCSI device. 8. If the SCSI device is recognized, power OFF the PC and install the next device. Verify recognition for the next device and then install. From this point on, the system should be up and running. 9.
FFD 3.5" SCSI Flash Disk User Manual 8.2.4 Solving Installation Problems The problems that arise in most installations are described below. Unstable Termination This occurs when there is a passive termination with Fast-SCSI devices on the bus. Incorrect Termination This occurs when there are too many devices terminated, or when the SCSI bus cable ends are not terminated. Cables Avoid using homemade, short, flat ribbon cables with bad contacts or cheap cables. Do not mix round cables with flat cables.
FFD 3.5" SCSI Flash Disk User Manual 9 Getting Help For technical assistance with the installation and configuration of your FFD, contact one of the sources listed below. Please have the following information available to aid the customer support representative in providing you with the best possible guidance: • Product and serial number of your FFD. • Description of your computer hardware (manufacturer, model, attached devices, etc.). • Description of your SCSI host adapter and associated drivers.
FFD 3.5" SCSI Flash Disk User Manual 10 Frequently Asked Questions (FAQs) About SCSI Q: What is SCSI? A: SCSI (Small Computer System Interface) is a general-purpose, parallel bus system. It originated with Shugart’s 1979’ SASI (Shugart Associates System Interface), and Shugart and NCR presented it to the ANSI in 1981. It became official in 1986, when the ANSI-committee X3T9.2 defined the SCSI-1 spec as Document X3.131-1986.
FFD 3.5" SCSI Flash Disk User Manual Q: What is Plug-and-play (P&P) SCSI? A: Plug-and-play SCSI is an extension of the generic plug-and-play specification. P&P is an approach for defining an auto-configuring environment for ISA boards. One of the key features of P&PSCSI is SCAM. Q: What is SCSI Configured AutoMagically (SCAM)? A: SCAM is a protocol for automatic SCSI ID assignment. It is included in the SCSI-3 parallel interface drafts.
FFD 3.5" SCSI Flash Disk User Manual Q: What types of SCSI connectors are available? A: There are many different connectors for SCSI. Some of them were defined with SCSI-1 and are now obsolete, such as the DB-50 connector. The most common connectors in use today are the 50-pin Centronics-type SCSI-1 connector, the 50-pin High-Density SCSI-2 connector and the DB-25 connector that Apple introduced for Macintosh computers. Most new host adapters and external devices use the SCSI-2 HD.
