6. Return the blue handle back to its horizontal position.
Step 9. If you have other devices to install or remove, do so now. Otherwise, go to “Completing the
installation” on page 87.
Step 10. Installing Fan 2A or 3A:
1. Orient the fan so that the fan cable points to the system board.
2. Lower the fan into the fan slot in the server and ensure that is it seated correctly.
3. Connect the system fan cable to the connector on the system board.
4. Insert the system fan cable into the cable retainer clip.
Step 11. If you have other devices to install or remove, do so now. Otherwise, go to “Completing the
installation” on page 87.
Memory module installation
The following notes describe the types of dual inline memory modules (DIMMs) that the server supports
and other information that you must consider when you install DIMMs.
• Confirm that the server supports the DIMM that you are installing, see http://www.lenovo.com/
serverproven/.
• When you install or remove DIMMs, the server configuration information changes. When you restart the
server, the system displays a message that indicates that the memory configuration has changed.
• The server supports only industry-standard double-data-rate 3 (DDR3), 1066, 1333, or 1600 MHz,
synchronous dynamic random-access memory (SDRAM) registered dual inline memory modules (DIMMs)
with error correcting code (ECC).
• The specifications of a DDR3 DIMM are on a label on the DIMM, in the following
format. ggge Rx ff -PC3- wwwwwm - aa - bb - cc - dd
where:
– ggg is the total capacity of the DIMM (for example, 1GB, 2GB, or 4GB)
– e is the number of ranks
1 = single-rank
2 = dual-rank
4 = quad-rank
– x ff is the device organization or bit width (for example, x4, x8, or x16)
4 = x4 organization (4 DQ lines per SDRAM)
8 = x8 organization
16 = x16 organization
– wwwww is the DIMM bandwidth, in MBps
6400 = 6.40 GBps (PC3-800 SDRAMs, 8-byte primary data bus)
8500 = 8.53 GBps (PC3-1066 SDRAMs, 8-byte primary data bus)
10600 = 10.66 GBps (PC3-1333 SDRAMs, 8-byte primary data bus)
12800 = 12.80 GBps PC3-1600 SDRAMs, 8-byte primary data bus)
14900 = 14.93 GBps PC3-1866 SDRAMS, 8-byte primary data bus)
17000 = 17.06 GBps (PC3-2133 SDRAMs, 8-byte primary data bus)
– m is the DIMM type
E = Unbuffered DIMM (UDIMM) with ECC (x72-bit module data bus)
