Installing The System Board
CAUTION: Exercise care when removing and installing the system board in the sled, to prevent
any damage to the system board.
1. Transfer the following components to the new system board:
– storage controller card(s)
– internal USB key
– processors and heat sinks, or processor/DIMM blanks
– memory modules and memory module blanks
CAUTION: Ensure that the system board plate is parallel with the chassis.
2. Slide the new system board into the open end of the server module chassis until the retention latch
engages.
When the board assembly is installed correctly, the tabs on the system board pan snap into the
corresponding openings in the floor of the server module chassis.
3. Replace the PCIe mezzanine cards in their original locations.
4. Reinstall the hard-drive backplane(s).
5. Replace the hard drives/SSDs.
Ensure that you reinstall the hard drives/SSDs in their original locations.
6. Reinstall the cooling shroud.
7. Install the SD card(s).
8. Close the server module.
9. Remove the plastic I/O connector covers from the back of the server module.
10. Install the server module in the enclosure.
11. Import your new or existing iDRAC Enterprise license. For more information, see the iDRAC7 User's
Guide, at dell.com/support/manuals.
System Memory
Your system supports DDR3 registered DIMMs (RDIMMs) and load reduced DIMMs (LRDIMMs). It supports
DDR3 and DDR3L voltage specifications.
NOTE: MT/s indicates DIMM speed in MegaTransfers per second.
Memory bus operating frequency can be either 800 MT/s, 1066 MT/s , 1333 MT/s, 1600 MT/s, or 1866
MT/s depending on the:
• DIMM type (RDIMM or LRDIMM)
• DIMM configuration (number of ranks)
• Maximum frequency of the DIMMs
• Number of DIMMs populated per channel
• DIMM operating voltage
• System profile selected (for example, Performance Optimized, Custom, or Dense Configuration
Optimized)
• Maximum supported DIMM frequency of the processors
