To install a drive cage, complete the following steps:
1. Make sure that the backplane or back plate is removed from the drive cage. (See “Removing the
backplane or back plate (3.5-inch drives)” on page 153 or “Removing the SAS backplane (2.5-inch
drives)” on page 155 for instructions, as applicable.)
2. Line up the drive cage with the drive bays on the front of the server.
3. Push the drive cage into the server until it stops.
4. Align the holes in the top of the drive cage with the holes in the top of the chassis; then, insert the
screws that secure the drive cage to the chassis.
5. Install the backplane or back plate. (See “Installing the backplane or back plate (3.5-inch drives)” on
page 153 or “Installing the SAS backplane (2.5-inch drives)” on page 155 for instructions, as applicable.)
6. Install the hard disk drives.
7. Go to “Completing the FRU replacement” on page 172.
Replacing the microprocessor and heat sink
The following notes describe the type of microprocessor that the server supports and other information that
you must consider when you install a microprocessor:
• The server supports one Intel land grid array (LGA) 1156 dual-core or quad-core microprocessor. The
type, speed, and L3 cache of the microprocessor depends on the server model.
• Read the documentation that comes with the microprocessor to determine whether you have to update
the server rmware. To download the most current level of server rmware, go to
http://www.lenovo.com/support.
• The microprocessor uses an integrated voltage regulator on the system board.
Removing the microprocessor
To remove the microprocessor, complete the following steps.
1. Read the safety information in “Important Safety Information” on page 1 and “Guidelines for trained
service technicians” on page 115.
2. Turn off the server and peripheral devices, and disconnect the power cords and all external cables.
3. Remove the server from the rack; then, remove the cover (see “Removing and installing the cover” on
page 119).
