Lenovo System x3650 M5 Installation And Service Manual page 193

Note: The optical drive is available only on some models.
To install an optional optical drive, complete the following steps:
Step 1. Read the safety information that begins on "Safety" on page v and "Installation guidelines" on page
305.
Step 2. Turn off the server and peripheral devices and disconnect the power cords and all external cables.
Note: When you disconnect the power source from the server, you lose the ability to view the
LEDs because the LEDs are not lit when the power source is removed. Before you disconnect the
power source, make a note of which LEDs are lit, including the LEDs that are lit on the operation
information panel, and LEDs inside the server on the system board.
Step 3. Remove the top cover (see "Removing the top cover" on page 162).
Step 4. Remove the optical drive filler panel if it is installed. Locate the blue release tab on the rear of the
optical drive filler panel; then, while you press the tab, push the optical drive filler panel out of the
drive bay.
Step 5. Remove the retention clip from the side of the optical drive filler panel. Save the optical drive filler
panel for future use.
Note: If you are installing an optical drive that contains a laser, observe the following safety
precautions.
