Installing Or Removing The Optical Module - Lenovo ThinkServer RD450 User Manual And Hardware Maintenance Manual

1. Remove all external media from the drives and turn off all attached devices and the server. Then,
disconnect all power cords from electrical outlets and disconnect all cables that are connected to
the server.
2. Prepare your server. See "Removing or extending the server from the rack cabinet" on page 61.
3. Remove the server cover. See "Removing the server cover" on page 61.
4. Locate the Lenovo ThinkServer RAID 500 PCIe Adapter. See "Server components" on page 25.
5. Remove the RAID 500 key from the Lenovo ThinkServer RAID 500 PCIe Adapter.
Note: If necessary, remove the Lenovo ThinkServer RAID 500 PCIe Adapter first for easier operation.
Then, reinstall the Lenovo ThinkServer RAID 500 PCIe Adapter. See "Installing or removing a PCI
Express card: Ethernet card, RAID card, and other supported types of PCI Express cards" on page 82.

6. Reinstall any parts or reconnect any cables that you have removed.
7. If you are instructed to return the old RAID 500 key, follow all packaging instructions and use any
packaging materials that are supplied to you for shipping.
What to do next:
• To work with another piece of hardware, go to the appropriate section.
• To complete the removal procedure, go to "Completing the parts replacement" on page 165. Because the
hardware RAID 5 and 50 levels are not available without the RAID 500 key, reconfigure RAID for your
server if necessary. For information about how to configure the hardware RAID, refer to the MegaRAID
SAS Software User Guide on the documentation DVD that comes with your server.

Installing or removing the optical module

The optical module enables you to connect two network devices with optical fiber cables. The optical
module is needed only on some PCIe cards.
Note: The optical module is extremely sensitive to ESD. Ensure that you read and understand "Handling
static-sensitive devices" on page 60 first and carefully perform the operation.
