Before you begin
Before you begin to install options in the server, read the following information:
v Become familiar with the safety and handling guidelines provided in “Safety
information” on page 127 and “Handling electrostatic discharge-sensitive devices”
on page 130 These guidelines will help you work safely while working with the
server or options.
v You do not need to turn off the server to install or replace hot-swap power
supplies, hot-swap drives, hot-swap fans, Active PCI (hot-plug) adapters, or
hot-plug USB devices.
v The orange color on components and labels in the server identifies hot-swap or
hot-plug components. This means that you can install or remove the component
while the system is running, provided that the system is configured to support
this function.
v The blue color on components and labels identifies touch points where you can
grip a component, move a latch, and so on.
v Make sure that you have an adequate number of properly grounded electrical
outlets for the 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 For a list of supported options for the eServer xSeries 350, refer to

installed.

and 100 mm (4 inches) at the rear of the server.
v The top cover is in place during normal operation.

operating.
