3. Format the drive  
The drive has been low level formatted at the factory. You do not need to  
perform another low level format on this drive unless you decide to perform  
certain diagnostics through the host adapter. If you do decide to perform a  
low level format, do not abort the format as this is likely to make the drive  
inoperable. A low level format, with verify turned on, will typically take 30  
minutes for ST336754FC models, 60 minutes for ST936701FC models, or  
90 minutes for ST973401FC models.

Protect against power failure or other power interruptions during the format.  
a. Turn on DC power to the host system.  
b. Boot the system from a system floppy, CD, or from a previously  
installed hard disc drive if there is one.

Handling precautions/Electrostatic discharge protection  
• Disc drives are fragile. Do not drop or jar the drive. Handle the drive only  
by the edges or frame.  
c. Format the drive.  
Caution. Formatting a drive erases all user data. Be sure that you under-  
stand this principle before formatting any hard disc drive. It is not  
necessary to format a drive that previously has been used to  
store data, unless your intention is to erase all user data.  
• Drive electronics are extremely sensitive to static electricity. Keep the  
drive in its antistatic container until you are ready to install it. Wear a wrist  
strap and cable connected to ground. Discharge static from all items near  
or that 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 any part is defective.  
• Do not apply pressure or attach labels to the circuit board or to the top of

systems. Please refer to your system or Fibre Channel host adapter (con-  
troller) manual for information about formatting and setting up the drive for  
use with your particular operating system.  
Hot plugging the drive  
This drive features hot plugging capabilities which allows you to insert and  
remove the drive without powering down the host system. Any time a drive  
is inserted or removed from a Fibre Channel loop, a short loop interruption  
occurs and the loop resynchronizes automatically to accommodate the  
added (or removed) drive.  
Electromagnetic compliance  
See the Safety and Regulatory Agency Specifications page, part number  
75789512, which was shipped with this installation guide.  
Drive startup options  
The drive’s motor will start spinning the discs based on the status of two sig-  
nals set by the host adapter. These two signals are called Start_1 and  
Start_2. There are four options as described below.

• Screwdriver and four M3 x .5 metric drive mounting screws  
• Forced-air ventilation to provide adequate drive cooling  
• Host system with Fibre Channel host adapter or backplane  
Most systems that host only a couple of drives use option 1 to enable all of  
the drives to start up immediately when power is applied to the drives. Sys-  
tems hosting larger numbers of drives may be configured to start drives at  
various times to avoid overloading the capabilities of the host system’s  
power supply.  
Installation instructions  
1. Mount the drive in the host system carrier or tray  
Most Fibre Channel host systems (including enclosures) provide a way to  
insert the drive using a carrier or tray, which allows the drive to be hot-  
plugged into the system’s Fibre Channel 40-pin single connector attach-  
ment (FC-SCA).  
If you want to change the startup option for the drive, please refer to the  
documentation provided with your Fibre Channel host adapter or host sys-  
tem.  
Troubleshooting  
Drive does not spin up. Remove and then reinsert the drive into the  
drive bay on the host-supplied carrier or tray. Make sure the drive makes  
firm contact with the host’s FC backpanel connector. Also, check the  
drive startup options for the Start_1 and Start_2 signals controlled from  
your host adapter. See “Drive Startup Options” above for the four possi-  
ble startup options.  
Mount the drive to the carrier or tray provided by the host system using four  
M3 x 0.5 metric screws. Do not over-tighten or force the screws. You can  
mount the drive in any orientation.  
Note. FC drives are designed to be attached to the host system without I/O  
or power cables.  
2. Insert the drive  
Computer does not seem to recognize the drive. Verify that the drive  
is enabled by the FC host adapter setup utility.  
Slide the carrier or tray into the appropriate bay in your host system. This  
connects the drive directly to your system’s 40-pin Fibre Channel single  
connector attachment (FC-SCA). The FC-SCA connector is normally  
located on a Fibre Channel backpanel.  
Note. There are no jumpers or terminators on the drive, and power is sup-  
plied through the 40-pin connector.
