Precautions
To avoid injury, data loss, and damage, observe these general precautions when installing or
servicing the storage system:
Using improper tools can result in damage to the storage system.
Prepare an ESD work surface by placing an antistatic mat on the floor or on a table near the
storage system. Attach the ground lead of the mat to an unpainted surface of the rack.
Always use the wrist-grounding strap provided with the storage system. Attach the grounding
strap clip directly to an unpainted surface of the rack.
Avoid contact between electronic components and clothing, which can carry an electrostatic
charge.
If applicable, ensure all cables are properly labeled and easily identifiable before you remove
a component.
Observe local occupational safety requirements and guidelines for heavy equipment handling.
Do not attempt to move a fully loaded equipment rack. Remove equipment from the rack before
moving it.
Use at least two people to safely unload the rack from the pallet.
Preventing Electrostatic Discharge
ESD can damage electrostatic-sensitive devices and microcircuitry. Proper packaging and grounding
techniques are important precautions to prevent damage. To prevent electrostatic damage, observe
the following precautions:
Transport products in electrostatic-safe containers, such as conductive tubes, bags, or boxes.
Keep static-sensitive parts in their containers until they arrive at static-free workstations.
