meant for use with computer systems. Do not
use household extension cords with your Sun
product.
The following caution applies only to devices with a
Standby power switch:
Caution – The power switch of this product
functions as a standby type device only. The
power cord serves as the primary disconnect
device for the system. Be sure to plug the
power cord into a grounded power outlet that
is nearby the system and is readily accessible.
Do not connect the power cord when the
power supply has been removed from the
system chassis.
The following caution applies only to devices with multiple
power cords:
Caution – For products with multiple power
cords, all power cords must be disconnected
to completely remove power from the system.
Battery Warning
Caution – There is danger of explosion if
batteries are mishandled or incorrectly
replaced. On systems with replaceable
batteries, replace only with the same
manufacturer and type or equivalent type

attempt to recharge them outside the system.
Do not dispose of batteries in fire. Dispose of
batteries properly in accordance with the
manufacturer's instructions and local
regulations. Note that on Sun CPU boards,

System Unit Cover
You must remove the cover of your Sun computer system
unit to add cards, memory, or internal storage devices. Be

Caution – Do not operate Sun products
without the cover in place. Failure to take this
precaution may result in personal injury and
system damage.
Rack System Instructions
The following or similar rack-mount instructions are
included with the installation instructions:
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 (for
example, use of power strips).
