Installation Safety Precautions
Follow these safety precautions when installing an SCv2000/SCv2020 storage system:
• Dell recommends that only individuals with rack-mounting experience install an SCv2000/SCv2020 storage system in a rack.
• The rack construction must support the total weight of the installed expansion enclosures. The design should incorporate stabilizing
features suitable to prevent the rack from tipping or being pushed over during installation or in normal use.
• To prevent the rack from tipping, slide only one storage system out of the rack at a time.
• Make sure that the storage system is always fully grounded to prevent damage from electrostatic discharge.
• When handling the storage system components, use an electrostatic wrist guard or a similar form of protection.
Electrical Safety Precautions
Always follow electrical safety precautions to avoid injury and damage to Storage Center equipment.
NOTE:
Disconnect power from the storage system when removing or installing components that are not hot-swappable.
When disconnecting power, first power down the storage system using the storage client and then unplug the power
cords from the power supplies in the storage system and storage system.
• Provide a suitable power source with electrical overload protection. All Storage Center components must be grounded before applying
power. Make sure that a safe electrical earth connection can be made to power supply cords. Check the grounding before applying
power.
• The plugs on the power supply cords are used as the main disconnect device. Make sure that the socket outlets are located near the
equipment and are easily accessible.
