Safety Information
Before beginning the replacement procedures, observe these precautions.
Warning: This equipment uses electrical power internally that is hazardous if the
equipment is improperly disassembled. Board removal and replacement should be
performed only by SGI-certified personnel.
Caution: Do not attempt to move CrayLink Interconnect cables. These cables are made
of sensitive copper strands and insulation material that can be damaged if they are
excessively bent, stretched, or stepped on.
This equipment is extremely sensitive and susceptible to damage by electrostatic
discharge (ESD) which is caused by the buildup of electrical static potential on clothing
and other materials. Use proper ESD preventive measures and observe these
precautions:
• Wear a properly grounded wrist strap when connecting and disconnecting
peripherals.
• Be sure that you and all the electrical equipment you handle are at ground potential
to avoid damage from ESD. Do not rely on the power source ground; the ground is
lost when the system is disconnected from the power source.
• Keep boards in their antistatic bags until you are properly grounded to the chassis
ground with a ground strap.
• Do not use an ohmmeter or a digital voltmeter on a board.
