Before you begin
Before you begin to install options in the server, become
familiar with the safety and handling guidelines provided in:
• “Safety information” on page 155;
• “Handling electrostatic discharge-sensitive devices” on
page 158; and
• “Safety notices (multi-lingual translations)” on page
159.
These guidelines will help you work safely while working
with the server or options.
• The blue color on components and labels identifies
touch points where you can grip a component, move a
latch, and so on.
