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 plug-in modules and components.
• 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.
• Remove any jewelry or metal objects from your body because they are excellent metal conductors
that can create short circuits and harm you if they come into contact with printed circuit boards or
areas where power is present.
• Do not lift a storage system chassis by the handles of the power supply units (PSUs). They are not
designed to hold the weight of the entire chassis, and the chassis cover may become bent.
• Before moving a storage system chassis, remove the PSUs to minimize weight.
• Do not remove drives until you are ready to replace them.
NOTE: To ensure proper storage system cooling, hard drive blanks must be installed in any hard
drive slot that is not occupied.
Install the Storage System in a Rack
Install the storage system and other Storage Center system components in a rack.
About this task
Mount the storage system and expansion enclosures in a manner that allows for expansion in the rack
and prevents the rack from becoming top‐heavy.
Steps
1. Secure the rails that are pre-attached to both sides of the storage system chassis.
a. Lift the locking tab on the rail.
b. Push the rail towards the back of the chassis until it locks in place.
2. Determine where to mount the storage system and mark the location at the front and rear of the
rack.
