enclosure with the rails while the other two people support the weight of the enclosure.
WARNING: Be sure to install enclosures 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: 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.
