Planning the installation 7
WARNING:
To reduce the risk of personal injury or damage to the equipment, be sure that:
•
The rack is bolted to the floor using the concrete anchor kit.
•
The leveling feet extend to the floor.
•
The full weight of the rack rests on the leveling feet.
•
The racks are coupled together in multiple rack installations.
•
Only one component is extended at a time. If more than one component is extended, a rack
might become unstable.
WARNING:
The chassis is very heavy. To reduce the risk of personal injury or damage to the
equipment, do the following:
•
Observe local occupational health and safety requirements and guidelines for manual
material handling.
•
Get help to lift and stabilize the product during installation or removal, especially when the
product is not fastened to the rails. 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.
WARNING:
To reduce the risk of personal injury or damage to the equipment, you must
adequately support the chassis during installation and removal.
WARNING:
Be sure to install the chassis starting from the bottom of the rack, and then work your
way up the rack.
WARNING:
To reduce the risk of personal injury from hot surfaces, allow the drives and the
internal system components to cool before touching them.
WARNING:
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.
CAUTION:
Always be sure that 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. For more information, refer to "Electrostatic
discharge (on page
)."
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.
Space and airflow requirements
To enable servicing and ensure adequate airflow, observe the following spatial requirements when deciding
where to install a rack:
•
Leave a minimum clearance of 121.9 cm (48.0 in) in front of the rack.
•
Leave a minimum clearance of 76.2 cm (30.0 in) in back of the rack.
•
Leave a minimum clearance of 121.9 cm (48.0 in) from the back of the rack to the rear of another rack
or row of racks.
