System Warnings and Cautions

Before installing the system, carefully review the following warnings and cautions:
WARNING: To reduce the risk of personal injury or damage to equipment,
heed all warnings and cautions throughout the installation instructions.
WARNING: To reduce the risk of electric shock or damage to the equipment,
only enter or perform service on specific parts of the system as instructed in
the user documentation.
WARNING: A risk of electric shock from high leakage current exists. Before
connecting the AC supply to the power enclosures, be sure that the electrical
outlets are properly earth grounded.
WARNING: A risk of injury from electric shock and hazardous energy levels
exists.
Each power enclosure has two separate power supply cords. A single
rack/cabinet may contain up to two power enclosures. In all cases, power is
supplied in a redundant fashion and removing any single source of power
does not necessarily shut down 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.
In the case of the server blade enclosures, shut off the circuit breakers to both
A and B power feeds and then disconnect both power feed cables before
servicing.
In the case of the power enclosures, shut off the circuit breakers to both A and
B power feeds and then disconnect both power cords from the wall outlet
before servicing.
WARNING: To reduce the risk of personal injury from hot surfaces, allow the
internal system components to cool before touching them.
