Warnings, cautions, and important messages Warnings, cautions, and important messages
WARNING: WARNING:
To reduce the risk of personal injury or damage to equipment, heed all warnings and cautions
throughout the installation instructions.
WARNING: WARNING: The frame is very heavy. To reduce the risk of personal injury or damage to the
equipment:
Observe local occupational health and safety requirements and guidelines for manual
material handling.
Remove all installed frame components from their frames before installing or moving the
frames.
Use caution and get help to lift and stabilize frames during installation or removal, especially
when the frame is not fastened to the rack.
WARNING: WARNING: Be sure to install frames starting from the bottom of the rack and work your way up
the rack.
These symbols, on power supplies or systems, indicate that the equipment is supplied by
multiple sources of power.
WARNING: WARNING: To reduce the risk of injury from electric shock,
remove all power cords to completely disconnect power from
the system.
Each enclosure has two or more power supply cords. A
single rack or cabinet may contain more than one enclosure.
Power may be supplied in a redundant fashion. Removing
any single source of power does not necessarily remove
power from any portion of the system. When performing
any service other than hot-plug module replacement, you
must completely disconnect all power to that portion of the
system.
When performing service procedures on enclosures, shut
off the circuit breakers to both A and B AC power feeds and
then disconnect all power cords from the outlets before
servicing.
WARNING: WARNING: To reduce the risk of personal injury from hot surfaces, allow the drives and the
internal system components to cool before touching them.
CAUTION: 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, see Electrostatic discharge.
CAUTION: CAUTION: When performing non-hot-plug operations, you must power down the compute module, the system, or both.
Use caution when performing other operations, such as hot-plug installations or troubleshooting.
CAUTION: CAUTION: Protect the equipment from power fluctuations and temporary interruptions with a regulating facility UPS
device. This device protects the hardware from damage caused by power surges and voltage spikes and keeps the
system in operation during a power failure.
