current ratings. Household extension cords do
not have overload protection and are not
meant for use with computer systems. Do not
use household extension cords with your Sun
product.
Caution – Your Sun product is shipped with
a grounding type (three-wire) power cord. To
reduce the risk of electric shock, always plug
the cord into a grounded power outlet.
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.

Caution – There is a sealed lead acid battery
in Sun Fire 280R units. Portable Energy

outside the system. Do not dispose of the
battery in fire. Dispose of the battery properly
in accordance with local regulations.
Caution – Do not operate Sun products
without the top cover in place. Failure to take
this precaution may result in personal injury
and system damage.
