[. . . ] Check all items against the shipping bill for required equipment and hardware to complete installation. Discrepancies, missing items, damaged equipment, etc. , should be reported to the sales representative from whom the drive was purchased. Inspection Inspect the drive for possible shipping damage. All claims for shipping damage should be filed with the carrier involved. Repacking If it is necessary to ship the drive, repack the drive with the original packing materials (saved during unpacking). Refer to section 5 for instructions. 18 Installation procedures With the site requirements completed, the enclosure designed, and the drive unpacked, you are ready to begin the installation. The following procedures are included in drive installation: · · · · · · · Setting the control board jumpers Installing the power supply Attaching an optional bezel Mounting the drive Connecting the system I/O cabling Grounding the system Synchronizing the spindle Setting the control board jumpers Caution. Do not remove the control board to set jumpers. The control board on the drive contains a number of jumpers that must be set correctly for normal operation of the drive. Figure 7 identifies jumpers, gives their locations on the control board, and lists the possible settings for normal drive operation. Installation 4 2 Terminator Power Source Jumper 1 Assign the terminal power jumpers as shown below. Initiator supplies power over the SCSI bus source for terminators. Drive supplies power for its own terminator resistor-paks but not to the SCSI bus (factory setting). Drive supplies power for the external terminator at the end of the daisychain. Terminator resistor-paks must be removed. 4 2 3 19 3 1 * * Recommended only for the last drive on the daisychain. Terminator Resistor-Paks (must be installed if drive is at either end of daisychain) ID2 ID1 SCSI Selectors ID0 Write Protect (WP) Master/Slave (MS) Spinup Delay option (SD) Start Command option (SC) SCSI Bus Parity Check option (PAR) Sweep Cycle option (SWP) J4A Select SCSI ID, write protect, and master/slave options by placing jumpers as shown below. SCSI ID = 0 SCSI ID = 1 SCSI ID = 2 SCSI ID = 3 SCSI ID = 4 SCSI ID = 5 SCSI ID = 6 SCSI ID = 7 Write Protect = On (prevents writing) Write Protect = Off (enables writing) Master drive for spindle sync Slave drive unless selected as the master by a SCSI command ID1 WP ID2 ID0 MS J4B Spinup Delay option (SD) Immediate spinup (if the Start Command option jumper is disconnected) Spinup delay equal to the SCSI bus ID multiplied by 10 seconds (if the Start Command option jumper is disconnected) Start Command option (SC) Start spindle according to the Spinup Delay option jumper Spindle spinup is delayed until a Start Unit command is received from the SCSI bus SCSI bus parity check (PAR) Enable parity check of SCSI bus data Ignore parity Sweep Cycle option (SWP) Disable sweep cycles (recommendation -- sweep cycles should be enabled at the system or subsystem level) Enable sweep cycles at the drive level SD SC SWP PAR Figure 7. Control board jumpers 20 Installing the power supply A power supply and AC power cord are available if desired. The power supply is configured before shipment to operate in one of two AC input voltage ranges. The voltage select plate on the power supply (see Figure 8) indicates the factorypreset voltage range. You may change the voltage range by setting the voltage select switch to the desired range. The power supply will be damaged if the voltage select is set for the low range (100­120 VAC) and a voltage in the high range (208­240 VAC) is applied. Ensure that the AC power cable is disconnected from the power supply.

When servicing the drive, observe all precautions listed under "Electrostatic discharge protection" in the preface. Failure to observe these precautions can result in serious damage to electronic assemblies. Be sure that the drive has completed spinning down before removing it from its mounting. [. . . ]
