Warnings And Cautions - HPE Edgeline EL8000 Setup And Configuration Manual

Warnings and cautions

WARNING: Only authorized technicians trained by Hewlett Packard Enterprise should attempt to repair this equipment.
All troubleshooting and repair procedures are detailed to allow only subassembly/module-level repair. Because of the
complexity of the individual boards and subassemblies, no one should attempt to make repairs at the component level
or to make modifications to any printed wiring board. Improper repairs can create a safety hazard.
WARNING: To reduce the risk of personal injury or damage to the equipment, consult the safety information and user
documentation provided with the server before attempting the installation.
Some servers contain high energy circuits, high current circuits, moving parts (such as fan blades), or any combination of
these hazards, that may be exposed if covers and access panels are removed while the product is connected to a power
source. These products are intended to be serviced only by qualified personnel who have been trained to deal with
these hazards. Do not remove enclosures or attempt to bypass any interlocks designed to guard against these
hazardous conditions.
WARNING: To reduce the risk of personal injury or damage to the equipment, be sure that:
• The leveling feet are extended to the floor.
• The full weight of the rack rests on the leveling feet.
• The stabilizing feet are attached to the rack if it is a single-rack installation.
• The racks are coupled together in multiple-rack installations.
• Only one component is extended at a time. A rack may become unstable if more than one component is extended for
any reason.
