remove all electrical current from the device, ensure that all power cords are disconnected from the 
power source.
Attention: 
•  Read “Installation guidelines” on page 58 to ensure that you work safely.
•  Power off the server and disconnect all power cords for this task.
•  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.
•  If the server is in a rack, remove it from the rack.
•  If foot stands are installed on the server, rotate them inwards and lay the server on its side for easier 
operation.
