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.
