WARNING:
• Be sure to bolt the rack to the floor by using the concrete anchor kit.
• Extend rack leveling feet to the floor.
• Rest the full weight of the rack on the leveling feet.
• In multiple rack installations, properly couple the racks together.
• Extend only one component at a time. If more than one component is extended, the rack might become
unstable.
• Observe local occupational health and safety requirements and guidelines for manual material handling.
• Use a lift or get help to lift and stabilize the product during installation or removal, especially when the product
is not fastened to the rails. You must adequately support the chassis during installation and removal. The
chassis weighs more than 81.65 kg (180.00 lb), so at least four people must lift the chassis into the rack
together. An additional person may be required to help align the chassis if the chassis is installed higher than
chest level.
• Install the chassis starting from the bottom of the rack, and then work your way up the rack.
• To reduce the risk of personal injury from hot surfaces, allow the drives and the internal system components to
cool before touching them.
• To reduce the risk of electric shock or damage to the equipment, never reach inside the chassis while the
system is powered up.
• Perform service on system components only as instructed in the user documentation.
• Always be sure that the equipment is properly grounded and that you follow proper grounding procedures
before beginning any installation procedure. Improper grounding can result in ESD damage to electronic
components.
CAUTION: When performing non-hot-plug operations, you must power down the chassis and/or the system.
However, it may be necessary to leave the chassis powered up when performing other operations, such as hot-plug
installations or troubleshooting.
