Safety Precautions

To avoid potential video and/or keyboard problems when using IBM products:
• If the building has 3-phase AC power, ensure that the computer and monitor
are on the same phase. For best results, they should be on the same circuit.
• Use only IBM-supplied cable to connect computers and KVM switches. IBM
warranties do not apply to damage resulting from user-supplied cable.
To avoid potentially fatal shock hazard and possible damage to equipment,
please observe the following precautions:
• Do not use a 2-wire extension cord in any IBM product confi guration.
• Test AC outlets at the computer and monitor for proper polarity and grounding.
• Use only with grounded outlets at both the computer and monitor. When
using a backup uninterruptible power supply, power the computer, the
monitor and the LCM off the supply.
NOTE: The AC inlet is the main disconnect.
Rack mount safety considerations
• Elevated Ambient Temperature: If installed in a closed rack assembly, the
operation temperature of the rack environment may be greater than room
ambient. Use care not to exceed the rated maximum ambient temperature
of the unit.
• Reduced Air Flow: Installation of the equipment in a rack should be such
that the amount of airfl ow 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
circuits might have on overcurrent protection and supply wiring. Consider
equipment nameplate ratings for maximum current.
• Reliable Earthing: Reliable earthing of rack mounted equipment should be
maintained. Pay particular attention to supply connections other than
direct connections to the branch circuit (for example, use of power strips).
