Memory options 
This server contains eight FBDIMM slots. You can expand server memory by installing supported 
Registered DDR-2 FBDIMMs. 
 
Memory configurations 
The server supports the following Advanced Memory Protection (AMP) options to optimize server 
availability. 
• Advanced ECC supporting up to 16 GB of active memory using 2-GB FBDIMMs. 
• Online Spare Memory providing additional protection against degrading FBDIMMs supporting up to 
14 GB of active memory and 2 GB of online spare memory utilizing 2-GB FBDIMMs. 
Maximum memory capacities for all AMP modes will increase with the availability of 4-GB and 8-GB 
FBDIMMs, including a maximum of 64 GB in Advanced ECC mode. For the latest memory configuration 
information, refer to the QuickSpecs on the HP website (http://www.hp.com
). 
The Advanced Memory Protection option is configured in RBSU. By default, the server is set to Advanced 
ECC mode. For more information, refer to HP ROM-Based Setup Utility. If the configured AMP mode is not 
supported by the installed FBDIMM configuration, the system boots in Advanced ECC mode. 
The following configuration requirements apply to all AMP modes: 
• FBDIMMS must be ECC Registered DDR-2 SDRAM FBDIMMs. 
• FBDIMMs must be installed in pairs. 
• FBDIMMS must be populated as specified for each AMP memory mode.  
Advanced ECC memory 
Advanced ECC memory is the default memory protection mode for this server. In Advanced ECC, the 
server is protected against correctable memory errors. The server provides notification if the level of 
correctable errors exceeds a pre-defined threshold rate. The server does not fail because of correctable 
memory errors. Advanced ECC provides additional protection over Standard ECC because it is possible 
to correct certain memory errors that would otherwise be uncorrectable and result in a server failure.  
Whereas standard ECC can correct single-bit memory errors, Advanced ECC can correct single-bit 
memory errors and multi-bit memory errors if all failed bits are on the same DRAM device on the 
FBDIMM. 
In addition to general configuration requirements, Advanced ECC memory also has the following 
configuration requirements: 
• FBDIMMs must be installed in pairs unless operating in single-FBDIMM mode. The server supports 
single-FBDIMM mode only in FBDIMM slot 1A. 
• FBDIMMs must be installed in sequential order, beginning with bank A. 
In Advanced ECC mode, FBDIMMs must be populated as specified in the following table, unless a single 
DIMM is used: 
 
Configuration Bank A 
1A and 5A Bank B 
2B and 6B Bank C 
3C and 7C Bank D 
4D and 8D 
1  X  — — — 
2 X X — — 
3 X X X — 
4 X X X X

Online spare memory configuration 
Online spare memory provides protection against degrading FBDIMMs by reducing the likelihood of 
uncorrectable memory errors. 
An understanding of single-rank and dual-rank FBDIMMs is required to understand memory usage in 
online spare mode. FBDIMMs can either be single-rank or dual-rank. Certain FBDIMM configuration 
requirements are based on these classifications. A dual-rank FBDIMM is similar to having two separate 
FBDIMMs, or ranks, on the same module. Although only a single FBDIMM module, a dual-rank FBDIMM 
acts as two separate FBDIMMs. The purpose of dual-rank FBDIMMs is to provide the largest capacity 
FBDIMM for the current DRAM technology. If the current DRAM technology allows for 2-GB single-rank 
FBDIMMs, a dual-rank FBDIMM using the same technology would be 4-GB. 
In online spare mode, a single rank of memory acts as the spare memory. For single-rank FBDIMMs, the 
entire FBDIMM acts as the spare memory. For a dual-rank FBDIMM, only half of the FBDIMM acts as the 
spare memory while the other half is available for operating system and application usage. 
If one of the non-spare FBDIMMs receives correctable memory errors at a higher rate than a specific 
threshold, the server automatically copies the memory contents of the degraded rank to the online spare 
rank. The server then deactivates the failing rank and automatically switches over to the online spare. 
Because FBDIMMs that experience a high rate of correctable memory errors have a higher probability of 
receiving an uncorrectable memory error, this effectively reduces the likelihood of uncorrectable memory 
errors that would result in server downtime. 
Online spare FBDIMM configuration requirements (in addition to general configuration requirements): 
• When only bank A is being used, it must be fully populated with dual-rank FBDIMMs. 
• For optimum memory usage, HP recommends all FBDIMMs be the same size with the same HP part 
number. If different sized FBDIMMs are used, a portion of the installed memory may not be utilized.  
In online spare mode, FBDIMMs must be populated as specified in the following table: 
 
Configuration Bank A 
1A and 5A Bank B 
2B and 6B Bank C 
3C and 7C Bank D 
4D and 8D 
1* X  — — — 
2 X X — — 
3 X X X X  
* Configuration 1 is only supported if using bank A, populated with dual-rank FBDIMMs. 
After installing FBDIMMs, use RBSU to configure the system for online spare memory support.  
Installing FBDIMMs 
  CAUTION:  To avoid damage to the hard drives, memory, and other system components, the air baffle, 
drive blanks, and access panel must be installed when the server is powered up. 
1. Power down the server (on page 16). 
2. Extend the server from the rack (on page 16). 
3. Remove the access panel (on page 18). 
4. Move the hard drive cables. 
5. Remove the air baffle. 
6. Open the FBDIMM slot latches.

8. Install the air baffle. 
9. Install the access panel (on page 19). 
10. If you are installing FBDIMMs in an online spare or mirrored configuration, use RBSU to configure 
this feature. 
 
Hard drive options 
Hard drive blank 
To remove a hard drive blank: 
1. Open the bezel (tower model) 
2. Squeeze the tabs to release the blank, and pull the blank out.

  NOTE:  Depending on model purchased, the server may look slightly different than shown.  
SATA or SAS hard drive 
To install the component: 
1. Open the bezel (tower model) 
2. Remove the existing hard drive blank (on page 36).

page 14). 
6. Close the bezel (tower model). 
7. Resume normal server operations.  
Removable media device options 
Accessing the removable media cage 
The server supports installation of optional internal storage devices. To access the components: 
1. Power down the server (on page 16). 
2. Do one of the following: 
• Open or remove the tower bezel, as needed (Open or remove the tower bezel on page 17). 
• Extend the server from the rack (on page 16). 
3. Remove the access panel (on page 18). 
  CAUTION:  Always populate each media bay with either a device or a blank. Proper airflow can only be 
maintained when the bays are populated. Unpopulated drive bays can lead to improper cooling and 
thermal damage.

Identifying guide screws 
When installing drives in the removable media bay, guide screws must be installed to make sure the 
drives correctly align in the drive cage. HP has provided extra guide screws, located behind the side 
access panel. Depending on the option, use 5.25 M3 metric screws or HD 6-32 shipping screws. The 
metric screws supplied by HP are black.
