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 
 
 
WARNING: This server 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. 
•  Get help to lift and stabilize the product during installation or removal, especially when the 
product is not fastened to the rails. HP recommends that a minimum of two people are required 
for all rack server installations. A third person may be required to help align the server if the 
server is installed higher than chest level. 
•  Use caution when installing the server in or removing the server from the rack; it is unstable 
when not fastened to the rails. 
 
 
 
 
 
WARNING: To reduce the risk of personal injury from hot surfaces, allow the drives and the 
internal system components to cool before touching them. 
 
 
 
WARNING: To reduce the risk of personal injury, electric shock, or damage to the equipment, 
remove the power cord to remove power from the server. The front panel Power On/Standby 
button does not completely shut off system power. Portions of the power supply and some internal 
circuitry remain active until AC/DC power is removed. 
 
 
 
CAUTION: Protect the server from power fluctuations and temporary interruptions with a 
regulating uninterruptible power supply. This device protects the hardware from damage caused 
by power surges and voltage spikes and keeps the system in operation during a power failure. 
 
 
 
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.
