Handling precautions/Electrostatic discharge pr otection

• Disc dr ives ar e frag ile. Do not drop o r jar the dr ive an d hand le the drive only by the edg es or frame.

• Drive electronics are extremely sensitive to static electricity. Keep the drive in its an tis tatic con t ai ne r un til you are read y to install it. Wear a wr is t s t rap and cab le co nn ect e d to gr oun d. Disc ha rge st a ti c fro m al l i tems ne ar or t hat will contact the drive. Never use an ohmmeter on any circuit boards.

• Turn off the power to the host system during installation.

• Always use forced-air ventilation when operating the drive.

• Use caution when troubleshooting a unit that has voltages present.

• Do not disassemble the drive; doing so voids the warranty.

• Return the entire drive for depot service if an y part is def ective.

• Do not apply pressure or attach labels to circuit board or drive top.

What you need

• Phillips screwdriver and four 6-32 UNC drive mounting screws

• F orced-air ventilation to provide adequate drive c ooling

• An unused dri ve power connector (not applicable to LC models)

To operate at LVD transfer rates, you may also need an LVD-capable SCSI host ad apter, LVD I/O cable and active negation exte rnal terminator.

Multimode interface

This dr ive can oper ate i n sing le- end ed (S E) or l ow volt age di ffere ntial (LVD) mode. This multimode capability provides backwards compatibility so you can use it with or without an LVD-capable host adapter. The primary benefits of LVD technology include faster transfer rates, reduced po wer consumption, increased allowable cable lengt hs, and improv ed device connectivity.

You can configure the drive to switch between SE and LVD modes automatically or force it to operate in SE mode only. To configure this option, see Figure 2.

To operate at the Ultra2 rates in LVD mode, all devices on the same

Note.

bus (cable) must be running in LVD mode. If you add any SE device to the bus, all devices on that bus operate in SE mode.

Caution.

Do not mi x LVD drives on the same bus w ith high volt a ge di f ferential (HVD) de vices–drive damage may occur.

Installation instructions

1. Set the SCSI ID

Deter mine which SCSI I Ds ar e alre ady be ing used i n the s ystem and t hen assig n this di sc drive a SCSI ID that isn’t alr eady being use d. Use the J6 connector located on the front of the drive to set the SCSI ID (see Figure 1).

• Most ST318404 drives are factory set with the SCSI ID set at 0. If this is the only S CS I drive in your syst em a nd the r e are no ot her SCSI devices on the daisychain, you can leave this drive’s SCSI ID set to 0 and proceed to the next step.

• The host system’s SCSI controller usuall y uses SCSI ID 7.

• If you have an S T318404LC model drive, t he host nor mally set s the ID over the I/O interface, so you don’t need to worry about this step.

• Some systems provide a cable designed to connect to the J5 jumper block on the drive to remotely set the ID. You can connect this cable to J5 and use the host-provided remote switch to set the SCSI ID.

Figure 1. Setting the SCSI ID

2. Configure termination

If you are installing the drive in a system that has other SCSI devices instal led , t e rminate only the end devi ces on the SCSI bus (ca ble ) . This dr i ve does no t h ave intern al termin at ors or any o th er way of addin g in te rnal te rmination on the dr ive. You must provide exte r nal te r mina tion w hen ter min ation is requ ired. Thi s is n orm al ly do ne by a ddin g an i nlin e te rm inato r on the e nd of the ca ble. Se e Fig ure 3 for an ill us tratio n show ing a sys tem confi gu ration that uses an extern a l ter m in ato r.

• Use active (ANSI SCSI-2 Alternative 2) single-ended terminators when terminating a bus operating in single-ended mode.

• Use SPI-2 -complia nt active low volta ge different ial termin ators whe n terminating a SCSI Ultra2 bus operating in LVD mode.

• The host adapter is normally on the end of the bus and internally terminated. You can configure your bus with another device on the end if you remove termination from the ho st adapter.

3. Configure te rminator power

Terminators have to get power from some source. The default configuration results in the dri ve not supply ing ter mination p ower to the bus. You should norm ally leave this dr ive se t at thi s defaul t unl ess your host sy stem req uires the drive to supply term ination pow er to the bus. To configure this d rive to supply termination power to the bus, place a jumper on J2 pins 1 and 2 as shown in Figure 2.

• Host systems designed to use LC drives normally provide termination power from the host adapter or other source. For this reason, LC model drives cannot be configured to provide termination power to the bus.

6. Mount the drive in the host system and connect cables

into the host system without I/O or power cables.

Caution.

Some mounting kits may contain screws that are too long to be fully tightened without causing damage to the drive. The maximum length for screws to exte nd into the dr ive moun ting holes is 0.15 inch (3.82 mm), measured from the outer surface of the drive.

a. Mount LW m odel drives to the host syst em’s chassis using four 6-32

UNC screws. Two mounting holes are in each side of the drive and there are four mounting holes in the bottom of the drive. Do not over-tighten or force the screws. You can mount the drive in any orientation.

b. Connec t the SCSI I /O cable in to the dri ve’s SCSI connector. Take care

not to s tre tch o r cr imp this cable, and do no t blo ck th e syste m ’s cooling air flow with the cable.

7. Format the drive

The drive has been

low le v el

formatted at the factory. You do not need to perform another low level format on this drive unless you decide to perform certain di agno st ics t hro ugh the ho st ada pter. If yo u do de cide to p erfor m a low level f ormat, do n ot abort the format as this is likely to make the drive inoperable. A low level forma t, with verif y turned o n, will typi cally take u p to one hour.

Protect against power failure or other power interruptions during the format. a. Turn on DC power to the h ost system. b. Boot t he system from a system floppy, CD, or from a previously installed

hard disc drive if there is one.

c. Format the drive.

Caution.

Formatt ing a dr ive erases a ll user d ata. Be s ure that yo u understand th is pri nciple before form attin g any hard di sc dr ive. It is not necess ary to format a drive that previously has been used to store data, unless your intention is to erase all user da ta. Seag ate is not

responsible for lost user data. Cheetah disc drives are designed to operate with a variety of operating systems. Ple as e refe r to yo ur s yst em or S C SI con tro ller ma nual for infor m ation about formatt ing an d s etting up t h e d r i ve. Som e quick desk top syste m notes
