The following safety requirements must be considered when the unit is mounted in a rack.

• The rack 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.

• The rack should comply with the airflow requirements detailed in the user guide.

• The 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 rack design should take into consideration the maximum operating ambient temperature for the unit, which is 35°C with a single cooling module fitted and 40°C when dual 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 0.8mA. 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 UL60950 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 RS-0800-LVD plug-in modules and components. Avoid contact with backplane components and module connectors, etc.

Preface

Data Security

• Power down your host computer and all attached peripheral devices before beginning installation.

• Each enclosure contains up to 8 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.

• Do not abandon your backup routines. No system is completely foolproof.

Special Tools and Equipment

There are no special tools required but in order to complete the assembly of some configurations you may need the following (not supplied):

• Cross head and slotted screwdrivers.

• Security keys (one of these should be included with your RS-0800-LVD enclosure for use with the drive locks).
