Unpacking and Inspecting the System
Remove the Silicon Graphics 750 system from the packaging container and check that the
following items are included:
• Silicon Graphics 750 system
•Silicon Graphics 750 Quick Start Guide (this document)
• Silicon Graphics 750 Documentation CD
Inspect the above items for evidence of mishandling during transit. If the contents
appear damaged, file a damage claim with the carrier immediately.
Save the boxes and packing materials for future use.
Note: If your system ships with software or media not listed above, please see its
accompanying documentation for installation instructions.
Warning: To avoid personal injury when unpacking the system, use only a
mechanical assist unit to lift the system off the shipping pallet. The system weighs
approximately 84 pounds (38 kilograms).

Power Consumption
The Silicon Graphics 750 power supply is rated for a maximum input AC power
consumption of 800 watts (7.5 amps at 100 Volts, 3.75 amps at 220 volts).
A fully loaded Silicon Graphics 750 system has a maximum input AC power
consumption of 500 watts (510 volt-amps, 4.6 amps at 110 Volts, 2.3 amps at 220 volts).

Choosing a Site
The Silicon Graphics 750 operates reliably within normal office environments. Select a
site that meets these criteria:
• Near a properly earthed, grounded, three-pronged power outlet, as follows:
– In the U.S. and Canada: a NEMA 5-15R outlet for 100-120 V or a NEMA 6-15R
outlet for 200-240 V.
– In other geographic areas: a properly earthed, grounded outlet in accordance
with the local electrical authorities and electrical code of the region.
• Clean and relatively free of excess dust.
• Well-ventilated and away from sources of heat, with the ventilation openings on the
system kept free of obstructions.
• Away from sources of vibration or physical shock.
• Isolated from strong electromagnetic fields and line noise caused by electrical
devices such as elevators, copy machines, air conditioners, large fans, large electric
motors, radio and TV transmitters, and high-frequency security devices.
• Access space provided so the power cords can be unplugged from the power
supply or the wall outlet. This is the only way to remove AC power from the
system.
• Clearance provided for cooling and airflow.
Caution: In regions that are susceptible to electrical storms, it is recommended that you
plug your system into a surge suppressor and disconnect any telecommunication lines
during electrical storms.

Starting the System
After making sure that you have set up the system properly and connected all the
required cables, you may now power on the system by pressing the power button.
The system starts and displays a welcome message. After that, a series of power-on
self-test (POST) messages appear. The POST messages indicate whether or not the
system is running correctly.
Note: If the system does not turn on or boot after pressing the power button, see the next
section (“Power-on Problems”) for the possible causes of the boot failure.
Power-on Problems
If the system does not boot after you have applied power, check the following factors that
might have caused the boot failure:
• The external power cable may be loosely connected.
Check the power cable connection from the power source to the power socket on
the rear panel. Make sure that the cable is properly connected and in good
condition.
• No power comes from the grounded power outlet.
Ask an electrician to check your power outlet.
Note: If you have performed the preceding actions and the system still fails to boot,
ask your dealer or a qualified technician for assistance.
