Removing the TR 500 Key
Attention: Do not open your server or attempt any repair before reading and understanding “Safety information”
on page iii and “Guidelines” on page 83.
This topic provides instructions on how to remove the TR 500 Key if your server has a ThinkServer RAID
500 Adapter with a TR 500 Key option installed.
Attention: Back up your data before you begin if you need to reconfigure RAID and reinstall the operating
system after removing the TR 500 Key.
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 500 Key from the ThinkServer RAID 500 Adapter, the hardware RAID 5 and RAID 50
levels will be disabled.
• Use any documentation that comes with the TR 500 Key and follow those instructions in addition to
the instructions in this topic.
To remove the TR 500 Key from the RAID card, 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 85.
3. Lay the server on its side for easier operation.
4. Locate the ThinkServer RAID 500 Adapter and remove any parts or disconnect any cables that might
impede your operation.
5. Remove the TR 500 Key from the ThinkServer RAID 500 Adapter. If necessary, you can remove the
ThinkServer RAID 500 Adapter first, remove the TR 500 Key from it, and then reinstall the ThinkServer
RAID 500 Adapter. See “Installing or removing the RAID card” on page 104.
Note: Carefully handle the TR 500 Key by its edges.
