Field-Installed Systems Vs. Factory-Racked Systems; Warning About Lifting The System - Dell EMC Data Domain DD6300 Installation Manual

Field-installed systems vs. factory-racked systems

Each component is intended to operate with all working power supplies installed.
l
Provide a suitable power source with electrical overload protection.
l
A safe electrical earth connection must be provided to each power cord. Check
l
the grounding of the power sources before applying power.
The plug on each power supply cord is used as the main device to disconnect
l
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
l
moving the system. Systems include two power supplies. To remove system power
completely, disconnect both power supplies.
The power connections must always be disconnected before removal or
l
replacement of a power supply module from the system.
A faulty power supply module must be replaced within 24 hours.
l
Do not lift system components by yourself. Systems weigh up to 80 lbs (36.29
l
kg), an ES30 expansion shelf weighs up to 68 lbs (30.8 kg), and a DS60 shelf
weighs up to 225 lbs (102 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 front handles on any modules. The handles are
l
not designed to support the weight of the populated shelf.
To comply with applicable safety, emission, and thermal requirements, covers
l
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 system or the chassis

Figure 1 Warning about lifting the system
To prevent the rack from becoming top-heavy, load the rack with storage shelves
l
beginning at the bottom and the system in the designated location.
Data Domain recommends that you wear a suitable antistatic wrist or ankle strap
l
for ESD protection. Observe all conventional ESD precautions when handling plug-
in modules and components.
Data Domain systems are available from the factory as components to install in an
existing rack on site, or pre-installed in a rack. The following sections provide
additional information about each type of installation.
