About this task
Attention: 
•  Read 
“Installation Guidelines” on page 47 and “Safety inspection checklist” on page 48 to ensure that you 
work safely.
•  Power off the server and peripheral devices and disconnect the power cords and all external cables. See 
“Power off the server” on page 62.
•  Prevent exposure to static electricity, which might lead to system halt and loss of data, by keeping static- 
sensitive components in their static-protective packages until installation, and handling these devices with 
an electrostatic-discharge wrist strap or other grounding system.
•  The rear drive cage is supported on some server models with thermal requirements. See 
“Thermal rules” 
on page 59
to ensure that the server is under permitted ambient temperature and the correct heat sink 
and system fans are used. If needed, replace your heat sink or system fan first.
