Installing or removing the RAID card

This topic provides instructions on how to install or remove the RAID card. If you are installing or removing
any other types of supported PCI Express cards, the procedure is similar.
You can install a supported RAID card into your server to provide advanced hardware RAID functions. To
support more than eight hard disk drives, the server must have a RAID card installed. For more information,
see "RAID card" on page 37 and "Configuring RAID" on page 72.
Installing the RAID card
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 install the RAID card.
Attention: Ensure that you back up your data before installing the RAID card because you might need to
reconfigure RAID and reinstall the operating system after installing the RAID card.
Before you begin, print all the related instructions or ensure that you can view the PDF version on another
computer for reference.
Notes:
• The RAID card is extremely sensitive to ESD. Ensure that you read and understand "Handling
static-sensitive devices" on page 84 first and carefully perform the operation.
