This symbol on an RJ-45 receptacle indicates a network interface connection.
WARNING:
To reduce the risk of electric shock, fire, or damage to the equipment, do
not plug telephone or telecommunications connectors into this receptacle.
This symbol
indicates the presence of a hot surface or hot component. If this surface is
contacted, the potential for injury exists.
WARNING: To reduce the risk of injury from a hot component, allow the surface to cool
before touching.
This symbol indicates that the component exceeds the recommended weight for one
individual to handle safely.
WARNING: 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.
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.
Server warnings and cautions
Before installing a server, be sure that you understand the following warnings and cautions.
WARNING: To reduce the risk of electric shock or damage to the equipment:
• Do not disable the power cord grounding plug. The grounding plug is an important safety
feature.
• Plug the power cord into a grounded (earthed) electrical outlet that is easily accessible at all
times.
• Unplug the power cord from the power supply to disconnect power to the equipment.
• Do not route the power cord where it can be walked on or pinched by items placed against it.
Pay particular attention to the plug, electrical outlet, and the point where the cord extends from
the server.
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: Do not operate the server for long periods with the access panel open or removed.
Operating the server in this manner results in improper airflow and improper cooling that can
lead to thermal damage.
Preparation procedures
To access some components and perform certain service procedures, perform one or more of the following
procedures:
• Power down the server (on page 23).
• Remove the access panel (on page 23).
