Electrical Safety Precautions
Always follow electrical safety precautions to avoid injury and damage to Storage Center equipment.
WARNING: Disconnect power from the storage system when removing or installing components that are not
•Provide a suitable power source with electrical overload protection. All Storage Center components must be grounded before applying power. Make sure that there is a safe electrical earth connection 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
•Do not work alone when working with
•Use rubber mats specifically 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. A faulty power supply must be replaced with a fully operational module power supply within 24 hours.
•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 supply power for complete isolation.
Electrostatic Discharge Precautions
Always follow electrostatic discharge (ESD) precautions to avoid injury and damage to Storage Center equipment.
Electrostatic discharge (ESD) is generated by two objects with different electrical charges coming into contact with each other. The resulting electrical discharge can damage electronic components and printed circuit boards. Follow these guidelines to protect your equipment from ESD:
•Dell recommends that you always use a static mat and static strap while working on components in the interior of the storage system chassis.
•Observe all conventional ESD precautions when handling
•Use a suitable ESD wrist or ankle strap.
•Avoid contact with backplane components and module connectors.
•Keep all components and printed circuit boards (PCBs) in their antistatic bags until ready for use.
General Safety Precautions
Always follow general safety precautions to avoid injury and damage to Storage Center equipment.
•Keep the area around the storage system chassis clean and free of clutter.
•Place any system components that have been removed away from the storage system chassis or on a table so that they are not in the way of foot traffic.
•While working on the storage system chassis, do not wear loose clothing such as neckties and unbuttoned shirt sleeves, which can come into contact with electrical circuits or be pulled into a cooling fan.
