• Disc drives are fragile. Do not drop or jar the drive. Handle the drive only 

by the edges or frame.

• 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 

the drive.

• 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

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). 

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
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.  

3. Format the drive
The drive has been 

 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.

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.

 disc drives are designed to operate with a variety of operating 

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.

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. 

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.

1 ........... Low .......Low......... Motor spins up at DC power on.

2 ........... High ......Low......... Motor spins up when the host adapter sends 

the SCSI Start command.

3 ........... Low .......High........ Motor spins up after a delay of 12 seconds 

times the physical address of the drive.

4 ........... High ......High........ The drive will not spin up.

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.

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.

• 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.

• Computer does not seem to recognize the drive. Verify that the drive 

is enabled by the FC host adapter setup utility.
