NOTE 
When the SC5200 Hot Swap Redundant Chassis is used, disregard steps 11 and 12. 
 
11. For chassis that require the PWT assembly (SC5200 Base chassis and reference chassis), 
reattach the fan assembly to the retention mechanism.  Pull the tabs at the sides of the retention 
mechanism apart slightly.  See Figure 15, 1.  Lower the fan assembly into the retention 
mechanism.  The tabs on the fan assembly (Figure 15, 3) will fit into the slots of the retention 
mechanism.  
(Figure 15, 1).  Pull out on the tabs located at the bottom of the fan assembly to snap them into 
place on the retention mechanism. 
12. For chassis that require the PWT assembly, reattach the CPU fan. 
Installing Memory 
The server board supports only DDR266-compliant DIMMs.

  Install from 256 MB to 12 GB of 
memory, using up to six DIMMs.   
DIMMs must be installed in pairs.  DIMM1, Bank 1 (the furthest DIMM pair from the MCH) must 
be populated first. 
No DIMM mixing is allowed within a bank.  Between banks only the DIMM size may be different.  
All DIMMs must be the same speed and architecture.  For a list of supported memory, visit the Intel 
Support website: http://support.intel.com/support/motherboards/server/SE7501HG2 
 
1.  Open both DIMM socket levers. 
2.  Insert the DIMM, making sure the notches in connector edge of the DIMM align correctly with 
the key in the slot. 
3.  Push down on the top edge of the DIMM until the socket levers snap into place. 
4.  Check that socket levers are securely latched.

 DDR200 compliant registered ECC DIMMs can be used only if 400 MHz processors are installed.
