Removing a ServeRAID SAS/SATA controller
Use this information to remove a ServeRAID SAS/SATA controller.
The ServeRAID SAS/SATA controller can be installed in the dedicated connector on the system board or PCI
riser-card slots (see "System-board internal connectors" on page 26 for the location of the connectors).
You can replace the ServeRAID controller with another supported ServeRAID controller. For a list of
supported ServeRAID controllers, see http://www.lenovo.com/us/en/ serverproven/.
Note: For brevity, in this documentation the ServeRAID SAS/SATA controller is often referred to as the
SAS/SATA adapter or the ServeRAID adapter.
To remove the SAS/SATA adapter from the system board, complete the following steps:
Step 1. Read the safety information that begins on "Safety" on page v and "Installation guidelines"
on page 31.
Step 2. Turn off the server and peripheral devices and disconnect all power cords.
Step 3. Remove the cover (see "Removing the cover" on page 189).
Step 4. Remove PCI riser-card assembly 1 if necessary (see "Removing a PCI riser-card assembly" on
page 220).
Step 5. Locate the SAS/SATA adapter between PCI slot 1 and microprocessor 1.
Step 6. Disconnect the signal cables and power cables from the connectors on the SAS/SATA adapter and
note their locations.
Step 7. Grasp the end of the SAS/SATA adapter near microprocessor 1 while you slide the brackets.
Slide the retention bracket (near the chassis) toward the chassis; then, slide the other retention
