Preface

DataDirect Networks StorageScaler 6000 User Guide Rev B 5

• The StorageScaler 6000 unit must only be operated from a power supply input voltage range of 200

V AC to 240 V AC.

• The plug on 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.

Warning To ensure protection against electric shock caused by HIGH LEAKAGE CURRENT (TOUCH

CURRENT), the StorageScaler 6000 must be connected to at least two separate and independent

sources. This is to ensure a reliable earth connection.

Warning The equipment is intended to operate with two (2) working PCMs. Before removing a PCM, please

disconnect the power from the power supply, by either the switch (where present) or by physically

removing the power source, prior to removing the PCM from the enclosure/shelf.

• Do not remove a faulty PCM unless you have a replacement unit of the correct type ready for

insertion.

• A safe electrical earth connection must be provided to the power cord.

• Provide a suitable power source with electrical overload protection to meet the requirements laid

down in the technical specification.

Warning Do not remove covers from the PCM. Danger of electric shock inside. Return the PCM to your

supplier for repair.

PCM Safety Label: Electric Shock Hazard Inside

Warning Operation of the Enclosure with ANY modules missing will disrupt the airflow and the drives will

not receive sufficient cooling. It is ESSENTIAL that all apertures are filled before operating the

unit.

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 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 ground for each unit and the rack.

• Each power supply in each unit has an earth leakage current of 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.

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 StorageScaler 6000 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 60 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

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
