Server warnings and cautions 
 
 
WARNING: 
This server is 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. Hitachi Vantara recommends that a minimum of two people are required for all rack server 
installations. If the server is installed higher than chest level, a third person may be required to help align the 
server. 
•
 
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.
 
 
WARNING:
 To reduce the risk of fire or burns after removing the energy pack: 
•
 
Do not disassemble, crush, or puncture the energy pack. 
•
 
Do not short external contacts. 
•
 
Do not dispose of the energy pack in fire or water. 
•
 
Do not expose the energy pack to low air pressure as it might lead to explosion or leakage of flammable 
liquid or gas. 
•
 
Do not expose the energy pack to temperatures higher than 60°C (140°F). 
After power is disconnected, battery voltage might still be present for 1s to 160s. 
 
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.
