• The rack design should take into consideration the maximum operating ambient temperature
for the unit, which is 35°C with a single Power Supply/Cooling module fitted and 40°C when
dual Power Supply/Cooling modules are fitted.
• The rack should have a safe electrical distribution system. It must provide overcurrent
protection 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 for each unit and the rack.
• Each power supply in each unit has an earth leakage current of 1.2mA. 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.
ESD Precautions
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 Altos S205F / S200F Storage System plug-in modules
and components. 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 16 removable disk drive modules. Disk units are fragile. Handle
them with care, and keep them away from strong magnetic fields.
•
All
the supplied plug-in modules and blanking plates must be in place for the air to flow
correctly around 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 any drive module, you may lose data.
– 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
• Ensure that all disk drives are removed from the enclosure before attempting to manhandle
or move the rack installation.
