System warnings and cautionsSystem warnings and cautions
WARNING:WARNING: This storage 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. Hewlett Packard Enterprise recommends that a minimum of two people are required for all rack storage
server installations. A third person may be required to help align the storage server if the storage server is installed
higher than chest level.
Use caution when installing the storage server in or removing the storage server from the rack; it is unstable when not
fastened to the rails.
WARNING:WARNING: To reduce the risk of personal injury from hot surfaces, allow the drives, power supplies, and internal system
components to cool before touching them.
WARNING:WARNING: To reduce the risk of personal injury, electric shock, or damage to the equipment, remove power from the
storage server by removing the power cord. The front panel Power On/Standby button does not shut off system power.
Portions of the power supply and some internal circuitry remain active until AC power is removed.
WARNING: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:CAUTION:
Protect the storage server from power fluctuations and temporary interruptions with a regulating UPS. This device
protects the hardware from damage caused by power surges and voltage spikes and keeps the storage server in operation
during a power failure.
CAUTION:CAUTION: Do not operate the storage server for long periods with the access panel open or removed. Operating the
storage server in this manner results in improper airflow and improper cooling that can lead to thermal damage.
