Server warnings and cautions
WARNING:
The chassis 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.
• Remove all installed components from the chassis before installing or moving the chassis.
• Use caution and get help to lift and stabilize the chassis during installation or removal, especially
when the chassis is not fastened to the rack.
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
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.
CAUTION:
To ensure proper thermal cooling, the four server tray slots must be populated with server nodes or
node blanks.
Space and airflow requirements
To allow for servicing and adequate airflow, observe the following space and airflow requirements when
deciding where to install a rack:
• Leave a minimum clearance of 63.5 cm (25 in) in front of the rack.
• Leave a minimum clearance of 76.2 cm (30 in) behind the rack.
• Leave a minimum clearance of 121.9 cm (48 in) from the back of the rack to the back of another rack or
row of racks.
Hewlett Packard Enterprise node s draw in cool air through the front door and expel warm air through the rear
door. Therefore, the front and rear rack doors must be adequately ventilated to allow ambient room air to
enter the cabinet, and the rear door must be adequately ventilated to allow the warm air to escape from the
cabinet.
CAUTION:
To prevent improper cooling and damage to the equipment, do not block the ventilation openings.
