Lenovo ThinkServer TD330 Manual page 122

Notes:
• If you remove the TR 100 or TR 300 Key, the onboard SATA or SAS software RAID 5 will be disabled
correspondingly.
• Use any documentation that comes with the TR 100 or 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.
Before you begin, print all the related instructions or ensure that you can view the PDF version on another
computer for reference.
To remove the TR 100 or 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. Remove the server cover. See "Removing the server cover" on page 77.
3. Lay the server on its side for easier operation.
4. Locate the iButton socket on the system board. If there is any PCI Express card installed on the PCI-E
slot 2 or PCI-E slot 3, it might block your access to the iButton socket on the system board. In this case,
you might need to remove the PCI Express card (such as the Ethernet card) first so that you can access
the iButton socket. See "Removing the Ethernet card" on page 96.
