Removing The Raid Card - Lenovo 70AL Maintenance Manual

Removing 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 65.
This topic provides instructions on how to remove the RAID card. This topic applies only to models that have
a RAID card installed.
Before you begin, print all the related instructions or ensure that you can view the PDF version on another
computer for reference.
Notes:
• Ensure that you back up your data before removing the RAID card because you might need to reconfigure
RAID and reinstall the operating system after removing the RAID card.
• If you remove the RAID card, you will lose the advanced SATA/SAS hardware RAID functions.
• Use any documentation that comes with the RAID card and follow those instructions in addition to
the instructions in this topic.
To remove 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 67.
3. Lay the server on its side for easier operation.
4. Remove the PCI card bracket assembly. See "Removing and reinstalling the PCI card bracket assembly"
on page 71.
5. Locate the RAID card, which is installed in the PCI-E slot 1 on the system board. See "System board
components" on page 38.
6. Remove any parts or disconnect any cables that might impede your operation.
7. Disconnect all cables from the RAID card and any other related parts.
Note: If you want to install a new RAID card after removing the old one, record the cable connections
before disconnecting the cables.
8. Remove the RAID card. The procedure is similar to that of the Ethernet card. See "Removing the
Ethernet card" on page 81.
Note: Carefully handle the RAID card by its edges.
9. Depending on your needs, do one of the following:
• Install a new RAID card to replace the old one and reconnect cables. See "Installing the RAID card"
on page 83.
• Install a PCI Express card slot bracket to cover the place and connect related cables to the system
board and the backplane. See "Connecting the cables" on page 35.
10. If you are instructed to return the old RAID card, 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 149. Then, you
need to reconfigure RAID for your server. See "Configuring RAID" on page 57.
