Service Guide

Appendix B: Safety Information
Intel® Server System SC5650HCBRP Service Guide 91
• Disconnect the AC power by unplugging all AC power cords from the system or wall outlet. Disconnect all
cables and telecommunication lines that are connected to the system.
• Retain all screws or other fasteners when removing access cover(s). Upon completion of accessing inside
the product, refasten access cover with original screws or fasteners.
• Do not access the inside of the power supply. There are no serviceable parts in the power supply. Return to
manufacturer for servicing.
• Power down the server and disconnect all power cords before adding or replacing any non hot-plug
component.
• When replacing a hot-plug power supply, unplug the power cord to the power supply being replaced before
removing the power supply from the server.
Caution: If the server has been running, any installed processor(s) and heat sink(s) may be hot. Unless you are
adding or removing a hot-plug component, allow the system to cool before opening the covers. To avoid the
possibility of coming into contact with hot component(s) during a hot-plug installation, be careful when removing or
installing the hot-plug component(s).
Caution: To avoid injury do not contact moving fan blades. If your system is supplied with a guard over the fan, do
not operate the system without the fan guard in place.
Rack Mount Warnings
The equipment rack must be anchored to an unmovable support to prevent it from tipping when a server or piece of
equipment is extended from it. The equipment rack must be installed according to the rack manufacturer's
instructions.
Install equipment in the rack from the bottom up, with the heaviest equipment at the bottom of the rack.
Extend only one piece of equipment from the rack at a time.
You are responsible for installing a main power disconnect for the entire rack unit. This main disconnect must be
readily accessible, and it must be labeled as controlling power to the entire unit, not just to the server(s).
To avoid risk of potential electric shock, you must implement a proper safety ground for the rack and each piece of
equipment installed in it.
Electrostatic Discharge (ESD)
Caution: ESD can damage disk 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 boards, and other components are properly installed.
• Attach the covers to the chassis according to the product instructions.
