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.
