Before you begin
Before you begin to install options in your server, read the
following information:
v Become familiar with the safety and handling guidelines
specified under “Working inside a server with power on”
on page 62, “Handling static sensitive devices” on
page 63, and read “Safety information” on page 192.
These guidelines will help you work safely while working
with your server or options.
v You do not need to turn off the server to install or
replace hot-swap power supplies, or hot-swap drives.
v The orange color on components and labels in your
server indicates hot-swap components. This means that
you can install or remove the component while the
system is running, provided that your system is
configured to support this function. For complete details
about installing or removing a hot-swap component, see
the information provided in this chapter.
v
The blue color on components and labels identifies
touch points where a component can be gripped, a latch
moved, and so on.
v
Make sure that you have an adequate number of
properly grounded electrical outlets for your server,
monitor, and any other options that you intend to install.
v Back up all important data before you make changes to
disk drives.
v
Have a small, flat-blade screwdriver available.
