Safe Handling
CAUTION: If this equipment is used in a
manner not specified by LaCie, the pro-
tection provided by the equipment may be
impaired.
In order to comply with applicable safety,
emission and thermal requirements, no
covers should be removed and all bays
must be populated with plug-in modules.
The system must not be run without all
modules in place.
Unplug the cables before you move the
enclosure.
Unplug the power cooling modules
(PCMs) if you believe the system has be-
come damaged in any way.
CAUTION: Fully assembled 12big Rack
Fibre 8 enclosure can weigh up to 27 kg
(59 lb.) Do not try to lift the enclosure by
yourself.
Always remove the power cooling mod-
ules and disk drives to minimize weight
before installing or removing the enclo-
sure into a rack.
CAUTION: The RJ-45 socket on the
RAID Controller is for Ethernet connection
only and must not be connected to a tele-
communications network.
Do not lift the enclosure by the handles
on the power supplies, as they are not de-
signed to support that weight.
Safety
✦The enclosure must only be operated
from a power supply input voltage
range of 100-240 VAC, 50-60 Hz.
✦The power supply cord is used as
the main disconnect device. Ensure
that the socket outlets are located
near the equipment and are easily
accessible.
✦The wiring installation must provide
a disconnect device close to the
equipment.
✦The RAID enclosure is designed
to power up and operate with two
power cooling modules and al-
low for a failure of one PCM while
continuing normal operations. Two
PCMs must always be installed.
✦If powered by multiple AC sources,
disconnect all source power for
complete isolation.
✦A faulty PCM must be replaced with
a fully operational PCM within 24
hours after failure. Do not remove
a faulty PCM unless you have a re-
placement of the correct type ready
for installation. The cooling fan por-
tion will continue to operate exclu-
sive of the power supply functions.
✦Before removing a PCM, disconnect
the power cord.
✦The power connection should al-
ways be disconnected prior to re-
moval of the power supply module
from the enclosure.
✦A safe electrical ground (earth) con-
nection must be provided to the
power cords. Check the grounding
of the enclosure before applying
power.
✦Provide a suitable power source
with electrical overload protection
to meet the requirements listed in
the technical specification.
CAUTION: Do not the remove the covers
from the Power Cooling Module. Danger
of electric shock inside. Return the module
to your supplier for repair.
✦Unplug the enclosure if you think
that it has become damaged in any
way and before you move it.
Equipment Handling
Precautions
✦All plug-in modules are part of the
fire enclosure and must only be
removed when a replacement can
be immediately added. The system
must not be operated without all
modules in place.
CAUTION: Operation of the enclosure
with ANY drive carrier module missing will
disrupt the airflow and the drives will not
receive sufficient cooling. It is ESSENTIAL
that all apertures are filled before oper-
ating the enclosure system. Dummy drive
carrier modules must be installed to un-
used drive bays.
Battery Safety
The RAID Controller employs a user re-
placeable battery pack. The controller
contains two batteries: the large user
replaceable Li-Ion battery, and the non-
user replaceable small yellow “SNAPHAT”
Lithium cell. For installation and removal
instructions, please refer to section 5.4.5.
Replacing a Battery Module.
CAUTION: There is a danger of explo-
sion if the battery is disposed of improp-
erly. Dispose of used batteries in ac-
cordance with LaCie’s instructions and
national regulations.
CAUTION: The batteries in the RAID
Controller may present a risk of fire, ex-
plosion or burns. Do not disassemble,
crush or heat above 60° C (140° F), or
incinerate. Replace the large battery with
the LaCie 12big Fibre 8 battery only. Use
of another battery may present a risk of
fire or explosion.
Safety Guidelines

LaCie 12big Rack Fibre 8 Foreword
User Manual page 6
Class 1 Laser Product
The LaCie 12big Rack Fibre 8 Controllers
are supplied with optical SFP Transceiver
modules. They contain a laser that com-
plies with Laser Class 1, US 21 CFR (J) &
EN 60825-1, UL (NRTL) and TUV.
IMPORTANT NOTE: The optical mod-
ules provided and installed by the end user,
must be a UL (or other North American
NRTL) RECOGNIZED COMPONENT, must
be approved by TUV (or other European
Product safety test house) and the laser in
the module must comply with Laser Class 1,
US 21 CFR (J) & EN 60825-1.
Rack System Precautions
The following safety requirements must be
considered when the enclosure is mount-
ed in a rack.
✦The rack construction must be ca-
pable of supporting the total weight
of the installed enclosure(s). The de-
sign should incorporate stabilizing
features suitable to prevent the rack
from tipping or being pushed over
during installation or in normal use.
✦Do not slide more than one enclo-
sure out of the rack at one time to
avoid the danger of the rack top-
pling over.
✦Always remove all PCMs and disk
drives to minimize weight before in-
stalling or removing the enclosure
into a rack.
✦When loading a rack with enclo-
sures, fill the rack from the bottom
up and empty from the top down.
✦The system must be operated with
a low pressure rear exhaust installa-
tion. (Back pressure created by rack
doors and obstacles not to exceed
5 pascals (0.5 mm water gauge)).
✦The rack design should take into
consideration the maximum oper-
ating ambient temperature for the
unit, which is 40°C (104°F) when
two power supply modules are fit-
ted.
✦The rack should have a safe elec-
trical distribution system. It must
provide overcurrent protection for
the enclosure and must not be over-
loaded by the total number of en-
closures installed in the rack. When
addressing these concerns, con-
sideration should be given to the
electrical power consumption rating
shown on the rack’s nameplate.
✦The electrical distribution system
must provide a reliable ground
(earth) for each enclosure and the
rack.
✦Each PCM in each enclosure has a
ground (earth) leakage current of
1.0 mA. The design of the electri-
cal distribution system must take
into consideration the total ground
leakage current from all the PCMs
in all the enclosures. The rack will
require labelling with “HIGH LEAK-
AGE CURRENT. Ground (earth)
connection is essential before con-
necting supply.”
✦The rack when configured with the
enclosures must meet the safety re-
quirements of UL 61000-3 and IEC
61000-3.
Data Security
✦Power down your host computer
and all attached peripheral devices
before beginning installation.
✦Each enclosure contains up to 12
removable disk drive modules. Disk
drives are fragile, handle them with
care and keep them away from
strong magnetic fields.
✦All the supplied plug-in modules,
dummy carriers and blank modules
must be in place for the air to flow
correctly around the enclosure and
also to complete the internal cir-
cuitry.
✦If the storage system is operated
with any plug-in modules, dummy
carriers, or blank modules missing
for more than a few minutes, the en-
closure can overheat, causing pow-
er failure and data loss. Such use
may also invalidate the warranty.
✦If you remove a drive module, re-
place it immediately. If the drive
module is faulty, replace it with one
of the same type and capacity (or
larger).
✦Ensure that all disk drives and pow-
er cooling modules are removed
from the enclosure before attempt-
ing to man-handle or move the rack
installation.
✦Do not abandon your backup rou-
tines. No system is completely infal-
lible.
Special Tools and
Equipment
There are no special tools required but in
order to complete the assembly of some
configurations you may need the follow-
ing:
✦Anti-tamper lock key for drive car-
rier modules (one key is included
with your enclosure).
✦Standard screwdrivers and wrench-
es.

User Manual page 8
1.2. 12big Rack Fibre Expansion
Enclosure
The 12big Rack Expansion enclosure is nearly identical to the RAID
enclosure except Disk I/O modules replace the RAID Controllers.
Expanding the number of disk drives is achieved by connecting one
to seven 12big Rack Expansion enclosures to the RAID enclosure.
This allows for the expansion of up to a maximum of 96 disk drives
per storage solution.
Using mini-SAS patch cables, the enclosures are interconnected
starting from the 12big Rack Fibre 8 RAID Controller(s) to the first
12big Rack Fibre Disk I/O module(s). Then the remaining Expan-
sion enclosures are connected from one set of Disk I/O modules to
the next enclosure’s Disk I/O modules. For details on cabling the
enclosures refer to 2.5. Cabling the Enclosures and 2.6. Cabling
Multiple Enclosures.

1.4. The Plug-in Modules
A LaCie 12big Rack Fibre 8 enclosure requires the following mod-
ules for normal operation:
✦(2) 580W AC Power Cooling Modules.
✦(1 or 2) LaCie 12big Rack Fibre 8 RAID Controller module(s)
for the 12big Rack Fibre 8.
✦(1 or 2) Disk I/O Modules for the 12big Rack Fibre Expansion
enclosure.
✦(1 to 12) Drive Carrier modules with either SAS or SATA disk
drives.
1.4.1. Power Cooling Module
CAUTION: To prevent overheating, do not operate the enclosure
with a PCM removed for more than 10 minutes.
Up to two 100-240V 580W dual fan power cooling modules are
supplied at the rear of the enclosure as part of the enclosure core
product (Fig. 06). This system provides an N+1 redundant power
configuration. If a PCM fails, the system will continue to operate nor-
mally up to 24 hours on the remaining PCM until the failed module
is replaced.
Each PCM features an ON/OFF switch and four LEDs that provide
operational status information. The cooling fans are speed con-
trolled via firmware. Should a firmware condition exists or a tem-
perature threshold exceeded, the fans speed will be increased to a
maximum value until the condition is corrected.
The enclosure is designed to power up and operate with two power
cooling modules and allows for a failure of one PCM while continu-
ing normal operations. Two PCMs must always be installed.

LaCie 12big Rack Fibre 8 System Overview
User Manual page 13
If the power supply component of the power cooling module fails,
leave the faulty PCM installed but remove the power cord. The dual
cooling fan component of the module will continue to receive power
from the enclosure and will continue to provide proper cooling. If
the fan component fails, both fans are not operating (loss of air-
flow), then replace the PCM. If a replacement is not immediately
available, install a PCM Blank module. In either case, replace the
defective power cooling module with a known good module as soon
as practical. If no blank module is available, then leave the defective
module in place until a replacement is available. It is recommended
that the replacement occur within 24 hours.
Voltage operating ranges are nominally 115V or 230V and are se-
lected automatically.
Four LEDs mounted on the rear panel of the Power Cooling Module
(Fig. 07) indicate the status of the module.
IMPORTANT INFO: Do not remove a faulty PCM unless you have
a replacement of the correct type ready for installation. PCM module
replacement should only take a few minutes to perform, but must
be completed within 10 minutes from removal of the failed PCM to
prevent overheating.

1.4.2. LaCie 12big Rack Fibre 8 RAID
Controller Module
One or two RAID Controller modules are supplied as part of the
12big Rack Fibre 8 enclosure core product (Fig. 08).
The hot swappable plug-in 12big Rack Fibre 8 RAID Controller
modules have been designed for integration into this SBB-compliant
(Storage Bridge Bay) form factor enclosure. The controller provides
dual external fibre channel (FC) cable interfacing for connectivity
to the host computer system, a SAS interface for connection to an
Expansion enclosure, an out-of-band Ethernet interface for Embed-
ded StorView and an out-of-band VT-100 interface for access to the
controller firmware program.
IMPORTANT INFO: Do not mix RAID Controller Modules and
Disk I/O Modules in the same enclosure.
The controller’s internal processor monitors conditions on each disk
drive port. It provides an enclosure management interface to devices
on the backplane, Power Cooling Modules, partner RAID Controller
module, and OPS panel. When the enclosure is supplied with dual
controllers, these processors operate in an active-active configura-
tion to allow for fail over and fail back.
The 12big Rack Fibre 8 RAID Controller provides support for Native
Command Queuing (NCQ). NCQ increases the performance of
SATA disk drives by allowing the individual disk to internally optimize
the order in which it executes read and write commands. This will re-
duce the amount of unnecessary movement of the drive’s heads re-
sulting in increased performance. The controllers also support a set
of performance tuning features like write-back cache management,
overload performance management, synchronized cache flush, tar-
get command thread balancing and sequential write optimization.
Description and use of these performance features are found in the
StorView Storage Management Software User Guide and in the VT-
100 RAID Configuration Utility User Guide.
The controller supports either 1 GB or 2 GB cache memory SD-RAM
modules.
SATA disk drives are supported and require an Active/Active MUX
transition card, see 1.4.5.3. MUX Transition Cards .

LaCie 12big Rack Fibre 8 System Overview
User Manual page 15
The RAID Controller module incorporates LED indicators for display-
ing the status of the controller, details of the LED status conditions
are shown in Fig. 09 and Table 03
The 12big Rack Fibre 8 RAID Controller module has the following
external ports:
✦Two external fiber channel “Host” ports that allow for fit-
ting of Small Form-Factor Pluggable (SFP) modules, with
auto-bypass at the output. Either or both of these SFP ports
can be used to provide connection to the host HBAs us-
ing Fibre Channel cables. Each host port operates at 8
Gb/s, giving an effective speed of 16 Gb/s.
These ports are also backwards compatible with 4
Gb/s, 2 Gb/s and 1 Gb/s hosts. The Host Port Status LED
will be illuminated steady when there is no I/O activity and
will flash indicating I/O activity and a separate status LED is
provided for each of the three operational speeds. The 2 Gb/s
and 1 Gb/s share the same LED. If the LED is extinguished, an
invalid link is indicated.
✦A SAS expansion port provides for expanding the number of
drives up to a maximum of 96, where up to seven additional
Expansion enclosures are connected via the 4-port mini-SAS
connector. The SAS expansion port operates at 3 Gb/s.
✦An RJ45 10/100BaseT Ethernet port provides for out-of -band
management and monitoring using the embedded StorView
Storage Management software when connected to a network.
IMPORTANT INFO: Only shielded Cat 5 (or better) cables should
be used for connection to the Ethernet port for Electromagnetic
Compatibility Directive 89/336/EEC (EMC) conformance.
✦A RS232 serial port provides an alternative user interface to
the RAID Controller’s RAID Configuration Utility.
IMPORTANT INFO: The RS232 port is a RCA type connector. It
requires a special RCA to DB9 cable.

1.4.2.1. Battery Module
The 12big Rack Fibre 8 RAID Controller module assembly includes
a removable backup battery module, located as shown in Fig. 09.
The battery module contains a user replaceable cell battery pack,
see Fig. 10. The battery pack provides protection of the controller
cache contents if the AC power fails. A fully charged battery should
provide up to 72 hours of protection.
The battery charging behavior is described as follows: during initial
startup, the battery charging system will enable the battery char-
ger to complete a full charge cycle. Once the charge completion
indication is detected from the charger, the charger is monitored
for an additional period of three hours for further charge activity.
If no charge activity is detected within that three hour window, the
battery is considered to be fully charged, and the charger is dis-
abled. Routinely, after every five days (7,200 minutes), the charger
is re-enabled to provide a top-off charge to the battery. Again, once
the charge completion indication is detected from the charger, the
charger is monitored for an additional period of three hours for fur-
ther charge activity. If no charge activity is detected within that three
hour window, the battery is considered to be fully charged, and the
charger is disabled until the next top-off charge interval elapses.
1.4.2.2. Fibre Channel Interface
The 12big Rack Fibre 8 RAID Controller module provides two Fibre
Channel SFP host interface connections. The controller uses two SFP
cages to capture the removable SFP optical modules. These connec-
tions are labeled Host 0 and Host 1. Please contact your supplier for
a list of qualified SFP optical components.
Each connection is bi-directional between the Fibre Channel host
side interface and the drives. The drives will not be presented to the
Host until they are configured into disk arrays and logical drives, and
then mapped by the controller.
TECHNICAL NOTE: There are no external terminators required
with Fibre Channel architecture.
IMPORTANT INFO: Optical SFP modules must be UL (or other
North American NRTL) RECOGNIZED COMPONENT and the laser
in the module must comply with Laser Class 1, US 21 CFR (J) and
EN 60825-1.

1.4.2.3. StoreView Management Software
The StorView Storage Management software is embedded on the
RAID Controller module and is a full-featured graphical HTML-
based software suite designed to configure, manage and monitor
the 12big Rack Fibre 8 and 12big Rack Fibre Expansion storage
solutions. The module is supplied configured with a base IP address
to allow the user to connect and access the controller’s embedded
StorView software. Please refer to 3.4. Starting StorView for further
information and the StorView Storage Management Software RAID
Module User Guide.
1.4.3. Disk I/O Module
The 12big Rack Fibre Expansion enclosure houses one or two Disk
I/O Modules. They provide drive expansion for the RAID enclosure.
When expanding the storage system, you may add up to seven Ex-
pansion enclosures. This will give you a total of eight enclosures
including the RAID enclosure for a maximum of 96 SAS or SATA
disk drives.
IMPORTANT INFO: Do not mix Disk I/O Modules and RAID
Controllers in the same enclosure.
Processors on the Disk I/O Modules provide enclosure management
and an interface to the devices on the backplane, Power Cooling
Modules and OPS panel, which monitors the internal functions. In
a dual module configuration, these processors operate in a master-
slave configuration to allow for path failover in the event of a single
module failure.
If only one Disk I/O Module is installed, a Blank I/O module must
be installed in the unused I/O Bay #1 (lower). The single Disk I/O
Module is installed in the I/O Bay #0 (upper).
Each Disk I/O Module has three SAS connectors and each connec-
tor has four adjacent LEDs. The LEDs indicate status or I/O activity
on that specific lane of the SAS port. The module also has a Fault
and ID LEDs. Refer to Table 04 for details on these LEDs.
In a multiple enclosure configuration, the “OUT” port on the RAID
Controller or Disk I/O Module connects to the “IN” port on the
Disk I/O Module in the next Expansion enclosure (12big Rack Fibre
Expansion). Please refer to section 2.6. Cabling Multiple Enclosures
for more information on cabling Expansion enclosures.
