Operations
This chapter describes the hardware operations carried out prior to and after installing or removing a
hardware option, or performing a server maintenance or troubleshooting procedure.
Before performing these hardware operations, review and observe the server warnings and cautions.
Server warnings and cautions
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:
To reduce the risk of personal injury from hot surfaces, allow the drives and the internal system
components to cool before touching them.
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:
To prevent improper cooling and thermal damage, do not operate the server with the media bay blank,
chassis cover
, or the front bezel removed.
CAUTION:
To prevent damage to electrical components, properly ground the
server before beginning any
installation procedure. Improper grounding can cause electrostatic discharge.
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.
Electrostatic discharge
Preventing electrostatic discharge
About this task
To prevent damaging the system, be aware of the precautions you must follow when setting up the system or
handling parts. A discharge of static electricity from a finger or other conductor may damage system boards or
other static-sensitive devices. This type of damage may reduce the life expectancy of the device.
