Replacing Storage System Components
This chapter describes how to remove and install components of the SCv3000 and SCv3020 storage system. This information assumes
that you have received the replacement component and are ready to install it.
Safety Precautions
Always follow these safety precautions to avoid injury and damage to Storage Center equipment.
If equipment described in this guide is used in a manner not specied by Dell, the protection provided by the equipment could be impaired.
For your safety and protection, observe the rules described in the following sections.
NOTE: See the safety and regulatory information that shipped with each Storage Center component. Warranty information is
included as a separate document.
Installation Safety Precautions
Follow these safety precautions when installing an SCv3000 and SCv3020 storage system:
• Dell recommends that only individuals with rack-mounting experience install an SCv3000 and SCv3020 storage system in a rack.
• When installing multiple expansion enclosures in a rack, ll the rack from the bottom up and empty the rack from the top down.
• 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.
• 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.
• Know the locations of the equipment power switches and the room's emergency power-o switch, disconnection switch, or electrical
outlet.
• Do not work alone when working with high-voltage components.
• Use rubber mats specically designed as electrical insulators.
• Do not remove covers from the power supply unit. Disconnect the power connection before removing a power supply from the storage
system.
• Do not remove a faulty power supply unless you have a replacement model of the correct type ready for insertion.
• Unplug the storage system chassis before you move it or if you think it has become damaged in any way. When powered by multiple AC
sources, disconnect all power sources for complete isolation.
