Appendix C: Safety Information QSSC-S4R Server System Product Guide
Version 1.0

To avoid risk of potential electric shock, a proper safety ground must be implemented for the rack and each
piece of equipment installed in it.
Elevated Operating Ambient - If installed in a closed or multi-unit rack assembly, the operating ambient
temperature of the rack environment may be greater than room ambient. Therefore, consideration should be
given to installing the equipment in an environment compatible with the maximum ambient temperature (Tma)
specified by the manufacturer.
Reduced Air Flow - Installation of the equipment in a rack should be such that the amount of air flow required for
safe operation of the equipment is not compromised.
Mechanical Loading - Mounting of the equipment in the rack should be such that a hazardous condition is not
achieved due to uneven mechanical loading.
Circuit Overloading - Consideration should be given to the connection of the equipment to the supply circuit and
the effect that overloading of the circuits might have on overcurrent protection and supply wiring. Appropriate
consideration of equipment nameplate ratings should be used when addressing this concern.
Reliable Earthing - Reliable earthing of rack-mounted equipment should be maintained.
Particular attention should be given to supply connections other than direct connections to the branch circuit
(e.g. use of power strips).
Electrostatic Discharge (ESD)
Caution: ESD can damage drives, boards, and other parts. We recommend that you perform all procedures at
an ESD workstation. If one is not available, provide some ESD protection by wearing an antistatic wrist strap
attached to chassis ground -- any unpainted metal surface -- on your server when handling parts.
Always handle boards carefully. They can be extremely sensitive to ESD. Hold boards only by their edges. After
removing a board from its protective wrapper or from the server, place the board component side up on a
grounded, static free surface. Use a conductive foam pad if available but not the board wrapper. Do not slide
board over any surface.
Other Hazards
Battery Replacement
Caution: There is the danger of explosion if the battery is incorrectly replaced. When replacing the battery, use
only the battery recommended by the equipment manufacturer.
Dispose of batteries according to local ordinances and regulations.
Do not attempt to recharge a battery.
Do not attempt to disassemble, puncture, or otherwise damage a battery.
Cooling and Airflow
Caution: Carefully route cables as directed to minimize airflow blockage and cooling problems. For proper
cooling and airflow, operate the system only with the chassis covers installed. Operating the system without the
covers in place can damage system parts. To install the covers:
 Check first to make sure you have not left loose tools or parts inside the system.
 Check that cables, add-in cards, and other components are properly installed.
 Attach the covers to the chassis according to the product instructions.
Laser Peripherals or Devices
Caution:
To avoid risk of radiation exposure and / or personal injury:
 Do not open the enclosure of any laser peripheral or device
 Laser peripherals or devices have are not serviceable
 Return to manufacturer for servicing
