Data Domain DD9800 System Installation and Storage Expansion Guide

Safety information

Review this list of important safety recommendations.

• All plug-in modules and blank plates are part of the fire enclosure and must be removed only when a replacement can be added immediately. The system must not be run without all parts in place.
• A DD9800 system must be operated only from a power supply input voltage range of 200–240 VAC and 50–60 Hz. ES30 shelves use 100-240 VAC and 50–60 Hz. DS60 shelves use 200–240 VAC and 50–60 Hz.
• Each component is intended to operate with all working power supplies installed.
• Provide a suitable power source with electrical overload protection.
• A safe electrical earth connection must be provided to each power cord. Check the grounding of the power sources before applying power.
• The plug on each power supply cord is used as the main device to disconnect power from the system. Ensure that the socket outlets are located near the equipment and are easily accessible.
• Permanently unplug the unit if you think it is damaged in any way and before moving the system. A DD9800 system includes four power supplies. To completely remove system power, you must disconnect all four power supplies.
• The power connections must always be disconnected prior to removal or replacement of a power supply module from any of the components in the system.
• A faulty power supply module must be replaced within 24 hours.

• Do not lift system components by yourself. A DD9800 system weighs up to 117 lbs (53.2 kg), an ES30 expansion shelf weighs up to 68 lbs (30.8 kg), and a DS60 shelf weighs up to 225 lbs (90.7 kg).

  CAUTION Data Domain systems are heavy. Use at least two people or a mechanical lift to move any system.

• Do not lift an expansion shelf by the handles on any modules. The handles are not designed to support the weight of the populated shelf.

• To comply with applicable safety, emission, and thermal requirements, covers must not be removed and all bays must be fitted with plug-in modules.
• Once removed from the shipping box, it is ok to lift the DD9800 system or the chassis with the four handles to place in a rack. You will need to remove the handles from the sides before sliding the system in the rack. The four handles should be saved for later use.

  

• Load the rack with storage shelves beginning at the bottom and the DD9800 system in the designated location to prevent the rack from becoming top-heavy.
• For ESD protection, Data Domain recommends that you wear a suitable antistatic wrist or ankle strap. Observe all conventional ESD precautions when handling plug-in modules and components.
• Do not extend components on slide rails until you have loaded at least three or more similarly weighted items in the rack, or unless the rack is bolted to the floor or overhead structure to prevent tipping.
