Server warnings and cautions
Before installing a server, be sure that you understand the following warnings and cautions.
WARNING: To reduce the risk of personal injury from hot surfaces, allow the drives and the internal
system components to cool before touching them.
CAUTION: The server must always be operated with the system covers on. Proper cooling is not
achieved when the system covers are removed.
CAUTION: Whenever installing hardware or performing maintenance procedures requiring access
to internal components, it is recommended that users first back up all server data to avoid loss.
IMPORTANT: Before removing any serviceable parts, determine whether the part is hot-plug or
non-hot-plug. If the device is non-hot-plug, you must power down the server. Non-hot-plug devices in
the server include the processor, all boards, memory modules, fans, expansion boards, and all
system drives.
IMPORTANT: Review the specifications of a new component before installing it to make sure it is
compatible with the server. When you integrate new components into the system, record its model
and serial number, and any other pertinent information for future reference. After completing any
removal or replacement procedure, run the diagnostics program to verify that all components
operate properly.
