WARNING:WARNING:
To reduce the risk of personal injury, electric shock, or damage to the equipment, disconnect the power cord to remove
power from the server. Pressing the Power On/Standby button does not shut off system power completely. Portions of the
power supply and some internal circuitry remain active until AC power is removed.
WARNING: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: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 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 server in operation during a power
failure.
CAUTION:CAUTION:
To prevent damage to electrical components, properly ground the server before beginning any installation, removal, or
replacement procedure. Improper grounding can cause electrostatic discharge.
CAUTION:CAUTION:
To avoid data loss, Hewlett Packard Enterprise recommends that you back up all server data before installing or removing
a hardware option, or performing a server maintenance or troubleshooting procedure.
CAUTION: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.
