Chapter 5 Preparing for Component Removal and Replacement 5-3
5.3.2 Placement of a Sun Product
Caution –
To ensure reliable operation of the Sun product and to protect it from
overheating, ensure equipment openings are not blocked or covered. Never place a
Sun product near a radiator or hot air register.
5.3.3 Power Cord Connection
Caution – Not all power cords have the same current ratings. Household extension
cords do not have overload protection. Do not use household extension cords with a
Sun product.
Caution – The power cord serves as the primary disconnect device for the system.
Be sure to connect the power cord into a grounded electrical receptacle 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.
5.3.4 Electrostatic Discharge
Caution – The boards and hard drives contain electronic components that are
extremely sensitive to static electricity. Ordinary amounts of static electricity from
clothing or the work environment can destroy components. Do not touch the
components themselves or any metal parts.
Caution – Wear an antistatic wrist strap and use an antistatic mat when handling
components. When servicing or removing system components, attach an ESD strap
to your wrist, then to a metal area on the chassis. Then disconnect the power cord
from the system and the wall receptacle. Following this caution equalizes all
electrical potentials with the system.
