Lenovo ThinkServer RD440 - Manual (Page 137)

This topic provides instructions on how to remove the TR 300 Key if your server has one installed on the
system board.
Before you begin, print all the related instructions or ensure that you can view the PDF version on another
computer for reference.
Notes:
• If you remove the TR 300 Key, the onboard SAS software RAID 5 will be disabled.
• Use any documentation that comes with the TR 300 Key and follow those instructions in addition to
the instructions in this topic.
• Depending on the model, your server might look slightly different from the illustration in this topic.
To remove the TR 300 Key, do the following:
1. Remove all 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. If the server is installed in a rack cabinet, remove the server from the rack cabinet and place it on a flat,
clean, and static-protective surface. See the Rack Installation Instructions that comes with the server.
3. Remove the server cover. See “Removing the server cover” on page 87.
4. Locate the iButton socket on the system board. See “System board components” on page 52. If there is
any PCI Express card installed on the riser card assembly 1, it might block your access to the iButton
socket on the system board. In this case, you need to remove the cooling shroud and then carefully lift
the riser card assembly 1 up so that you can access the iButton socket. You do not need to disconnect
any cables from the riser card assembly 1 or completely remove the riser card assembly 1.
