Rack System Precautions
The following safety requirements must be considered when the unit is mounted in a rack.
• The rack construction must be capable of supporting the total weight of the installed enclosure(s)
and the design should incorporate stabilizing 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.
Warning It is recommended that you do not slide more than one enclosure out of the rack at a time, to avoid
danger of the rack tipping over.
• When mounting in a rack, ensure that the enclosure is pushed fully back into the rack.
• The system must be operated with low pressure rear exhaust installation. (The back pressure
created by rack doors and obstacles should not exceed 5 pascals [0.5mm water gauge].)
• The rack design should take into consideration the
maximum operating ambient temperature for the
unit is 35°C.
• The rack should have a safe electrical distribution system. It must provide over current protec
tion for
the unit and must not be overloaded by the total number of units installed in the rack. Consideration
of the units nameplate rating should be used when addressing these concerns.
• The electrical distribution system must provide a reliable earth ground for each unit and the rack.
• Each power supply in each unit has an earth leakage current o
f 1.5mA. The design of the electrical
distribution system must take into consideration 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 requirements of UL 60950 and IEC
60950.

Caution It is recommended that you fit and check a suitable anti-static wrist or ankle strap and observe all
conventional ESD precautions when handling StorageScaler 6000 plug-in modules and componen ts.
Avoid contact with backplane components and module connectors, etc.
Data Security
• Power down your host computer and all attached peripheral devices before beginning installation.
• Each enclosure contains up to 60 removable disk dri
ve modules. Disk units are fragile. Handle them
with care, and keep them away from strong magnetic fields.
• All th
e supplied plug-in modules and blanking plates must be in place for the air to flow correctl y
through the enclosure and also to complete the internal circuitry.
• If the subsystem is used with modules or blanking
plates missing for more than a few minutes, the
enclosure can overheat, causing power failure and data loss. Such use may also invalidate the
warranty.
• If you remove a drive module, replace it immediately. If
it is faulty, replace it with a drive module of
the same type and capacity
