Safety Guidelines

LaCie 12big Rack Network Foreword
User Manual page 6
Rack System Safety
Precautions
The following safety requirements must be
considered when the unit is mounted in a
rack.
✦The rack construction must be ca-
pable of supporting the total weight
of the installed enclosure(s) and the
design should incorporate stabiliz-
ing features suitable to prevent the
rack from tipping or being pushed
over during installation or in normal
use.
✦When loading a rack with the units,
fill the rack from the bottom up and
empty from the top down.
✦Always remove all modules and
drives, to minimize weight, before
loading the chassis into a rack.
CAUTION: To avoid danger of the rack
toppling over, under no circumstances
should more than one enclosure be drawn
out of the cabinet at any one time.
✦The system must be operated with
low pressure rear exhaust installa-
tion. (Back pressure created by rack
doors and obstacles not to exceed 5
pascals [0.5mm water gauge]).
✦The rack design should take into
consideration the maximum oper-
ating ambient temperature for the
unit, which is 35°C.
✦The rack should have a safe electri-
cal distribution system. It must pro-
vide overcurrent protection for the
unit and must not be overloaded by
the total number of units installed
in the rack. When addressing these
concerns consideration of the elec-
trical power consumption rating
shown on the nameplate.
✦The electrical distribution system
must provide a reliable earth for
each unit and the rack.
✦Each Power Supply Unit has an
earth leakage current of 1.4mA.
The design of the electrical distribu-
tion system must take into consider-
ation the total earth leakage current
from all the power supplies in all the
units. The rack will require labelling
with “HIGH LEAKAGE CURRENT.
Earth connection essential before
connecting supply”.
✦The rack when configured with the
units must meet the safety require-
ments of UL 60950-1 and IEC
60950-1.

1.7. Power Supply Unit
AC-DC Power is provided by two dual-redundant power supply units
with specific load capability, mechanical packaging and a power
cage with output loom to suit this application.
A Power Supply Mounting Cage is fitted in the rear of the enclosure
as part of the subsystem core product. The cage houses two indi-
vidually hot pluggable 850W AC Power Supply Units (PSUs), each
with its own IEC inlet connector and failure indicator.
PSU voltage operating ranges are nominally 100V - 240V AC, se-
lected automatically. A typical PSU is shown in Fig. 07.
Each PSU incorporate an Audible Alarm to indicate when a fault
state is present and a bi-color (Green/Red) LED which indicates the
PSU status.
1.7.1. Multiple Power Supply Units
The LaCie 12big Rack Network includes two PSUs fitted in the Pow-
er Supply Mounting Cage, providing dual power sources for the sys-
tem so that if one PSU fails the other maintains the power supply and
enclosure operation is not affected while you replace the faulty unit.
PSU replacement should only take a few minutes to perform but
must be completed within 10 minutes from removal of the failed
PSU.
Fig. 07 - Power Supply Unit

LaCie 12big Rack Network System Overview

✦P3 12V power connector
✦P4 Peripheral power connector (2 x 4 pin).
✦P5 PSUI connector (5 pin)
✦P5 SM bus connector (2 pin)
1.8. Cooling Fans
The Cooling Fans are high speed single rotor axial fans. Ten fans
are housed in a Cooling Cage, located centrally within the enclo-
sure, between the drive bays and the Motherboard, as shown in Fig.
02. This ensures maximum airflow through the PSU and minimizes
noise.
Airflow is front to rear with cooling air being drawn across the drives,
through the fans and pressurizing the rear of the enclosure. The
pressurized rear allows the PSU to draw the air that it requires, and
perforations at the rear of the chassis allow cooling airflow over the
Processor heatsinks, memory, motherboard and PCI cards.
The cooling system must be operated with low pressure rear exhaust
installation [Back pressure created by rack doors and obstacles not
to exceed 5 pascals (0.5mm Water gauge)]
The cooling system provides sufficient capacity to ensure that drive
maximum temperatures are not exceeded at 35°C ambient with one
fan failed at sea level.
The Cooling Cage contains ten individual high speed single rotor
axial fans, individually connected to and interfacing with the Enclo-
sure Management PCB. This interface provides power and speed
control to the fans and returns tacho output from each fan

rier. Each drive bay will house a single Low Profile 1.0 inch high, 3.5
inch form factor disk drive in its carrier. The carrier has mounting
locations for SAS/SATA drives.
Each disk drive is enclosed in a sheet steel carrier which provides
excellent thermal conduction, radio frequency and electro-magnetic
induction protection and affords the drive maximum physical protec-
tion.
The front cap also supports an ergonomic handle which provides the
following functions:
✦Camming of carrier into and out of drive bays.
✦Positive ‘spring loading’ of the drive/backplane connector.
1.9.1. Drive Status Indicator
Disk drive status is monitored by a Green LED and an Amber LED
mounted on the front of each Drive Carrier module, under ESI pro-
cessor control, shown in Fig. 10. Please refer to 4.2.4. Drive Carrier
Module LEDs for a description of the LED states.
1.9.2. Anti-tamper Locks

munications protocol, which is the only supported communication
method to the enclosure firmware. Other tools may cause unpredict-
able side effects and hence are not supported.
SES support is at ANSI SES 2.0 level and supports SES Pages 0, 1, 2,
5, 7, Ah and Eh. Download of the Enclosure firmware is supported
via SES Page Eh. During firmware download all RAID data activity
must be stopped.

2.3.5. Rack Installation Pre-Requisites
The LaCie 12big Rack Network Enclosure is designed for installa-
tion into an industry standard 19 inch cabinet capable of holding
the unit.
✦Minimum depth 707mm (27.83 inches) from rack posts to
maximum extremity of enclosure (excludes rear cabling).
✦Weight: up to 30kg, dependent upon configuration, per en-
closure.
✦A minimum gap of 25mm (1inch) clearance between the rack
cover and front of drawer; and 50mm (2 inches) rear clear-
ance between rear of drawer and rear of rack is recommended
in order to maintain the correct air flow around the enclosure.
✦The rack should present a maximum back pressure of 5 pas-
cals (0.5mm water gauge).
CAUTION: Operation of the enclosure system with ANY modules
missing will disrupt the airflow and the drives will not receive suf-
ficient cooling. It is ESSENTIAL that all apertures are filled before
operating the unit. Dummy Drive Carriers and/or Blanking Plates
are available for this purpose.
2.4. Rack Mounting Rail Kit
A set of rack mounting rails is available for use in 19 inch rack
cabinets. These rails have been designed and tested to handle the
maximum enclosure weight and to ensure that multiple enclosures
may be installed without loss of space within the rack. Use of other
mounting hardware may cause some loss of rack space.
Please contact your supplier to ensure suitable mount rails are avail-
able for the rack you are using.
Important Please refer to section Rack System Safety Precautions be-
fore you begin the assembly procedure.
