Safety and Environmental Considerations
WARNING Voltages are present at various locations within the server whenever an AC power
source is connected. This voltage is present even when the main power switch is in
the off position.
Ensure that the server is powered-down and all power sources have been
disconnected from the server prior to attempting the following procedures.
Failure to observe this warning could result in personal injury or damage to
equipment.
Communications Interference
HP system compliance tests are conducted with HP supported peripheral devices and shielded cables, such as
those received with the server. The server meets interference requirements of all countries in which it is sold.
These requirements provide reasonable protection against interference with radio and television
communications.
Installing and using the server in strict accordance with HP's instructions minimizes the chances that the
server will cause radio or television interference. However, HP does not guarantee that the server will not
interfere with radio and television reception.
Take these precautions:
• Use only shielded cables.
• Install and route the cables per the instructions provided.
• Ensure that all cable connector screws are firmly tightened.
• Use only HP supported peripheral devices.
• Ensure that all panels and cover plates are in place and secure before server operation.
Electrostatic Discharge Information
HP servers and peripherals contain assemblies and components that are sensitive to electrostatic discharge
(ESD). Carefully observe the precautions and recommended procedures in this manual to prevent component
damage from static electricity.
WARNING Connect to ground with a wrist strap. Connection can be made to any grounded
metal assembly in the cabinet. Both you and the electronic devices must be
grounded to avoid static discharges that may cause damage.
Take these precautions:
• Prepare an ESD safe work surface large enough to accommodate the various assemblies handled during
the upgrade. Use a grounding mat and an anti-static wrist strap, such as those included in the ESD Field
Service Kit
• The anti-static bag can not function as a static dissipating mat. Do not use the anti-static bag for any
other purpose than to enclose a product.
