Online spare memory configuration 
Online spare memory provides prot
ection against degrading FBDIMMs  by reducing the likelihood of 
uncorrectable memory errors. This protection is  available without any operating system support. 
An understanding of single-rank and dual-rank FBDIM Ms 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 du al-rank FBDIMM is similar to having two single-rank 
FBDIMMs on the same module. Although only a sing le 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 cu rrent 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 ra nk 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 availabl e 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 an d automatically switches over to the online spare. 
Because FBDIMMs that experience a high rate of  correctable memory errors also have a higher 
probability of receiving an uncorrectable memory e rror, this configuration reduces the likelihood of 
uncorrectable memory errors that  would result in server downtime. 
Online spare is performed per bran ch of the memory controller. For a server with both branches 
populated, two ranks are used for online spare memo ry. One branch can fail over to the associated 
online spare while the other  branch is still protected. 
Each branch is made up of two banks: 
•  Branch 0 contains banks A and C 
• Branch 1 contains banks B and D 
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. 
• If banks A and C are being used, they must be fully populated. 
• If installed, bank A and bank C must contain FBDIMMs with identical part numbers.  
• If installed, bank B and bank D must also  contain FBDIMMs with identical part numbers. 
In online spare mode, FBDIMMs  must be populated as specified in the following table: 
 
Configuration Branch 0 
Bank A 
1A and 3A Branch 0 
Bank C 
2C and 4C Branch 1

* Configuration 1 is only supported if using

After installing FBDIMMs, use RBSU to configure the system for online spare memory support 
(Configuring online spare memory  on page 60). 
 
Mirrored memory configuration 
Mirroring provides protection agains t uncorrectable memory errors that would otherwise result in server 
downtime. 
Mirroring is performed on the branch level.  Branch 0 and branch 1 mirror each other. 
Each branch maintains a copy of all memory contents. Memory  writes go to both branches. Memory 
reads  come from only one of the two branches (unless  an uncorrectable error occurs). If a memory read 
on one branch returns incorrect data due to an unco rrectable memory error, the system automatically 
retrieves the proper data from the other branch. A  branch is not necessarily disabled (thus losing 
mirroring protection) because of a si ngle uncorrectable error. Mirroring protection is not lost because of 
transient and soft uncorrectable errors, resulting in sy stems that maintain mirroring protection (and thus 
improved uptime) unless there is  a failure of both branches. 
Mirrored memory FBDIMM configuration requirements (i n addition to general configuration requirements): 
• Banks A and B must be fully populated. 
• Bank A and bank B must contain FBDIMMs with id entical part numbers. If installed, bank C and 
bank D must also contain FBDIMMs with identical part numbers. 
When using mirrored memory mode,  FBDIMMs must be populated as specified in the following table:

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 in stalled when the server is powered up. 
1. Power down the server (on page  20). 
2. Extend the server from the rack (on page  20). 
3. Remove the access panel (on page  21). 
4. Move the hard drive cables. 
5.  Remove the air baffle. 
6. Open the FBDIMM slot latches.

Install the FBDIMM. 
 
8. Install the air baffle. 
9. Install the access panel (on page  22). 
If you are installing FBDIMMs  in an online spare or mirrored configuration, use RBSU ( HP ROM-Based 
Setup Utility  on page 59) to configure this feature. 
For more information about LEDs and troubleshooting  failed FBDIMMs, see Systems Insight Display LEDs 
and internal health LED combinations (on page  14). 
 
Hot-plug SAS hard drive options 
When adding hard drives to the server, ob serve the following general guidelines:  
• The system automatically sets all device numbers. 
• If only one hard drive is used, install it in the bay with the lowest device number ( SAS device 
numbers  on page  15). 
• Hard drives must be SFF types. 
• Drives should be the same capacity to provide the  greatest storage space efficiency when drives are 
grouped together into the same drive array.

DC power supply option 
  WARNING:  To reduce the risk of electric sh ock, fire, and damage to the equipment, this 
product must be installed in accordan ce with the following guidelines: 
•   This power supply is intended only for installa tion in HP servers located in a restricted 
access location.  
•   This power supply is not intended for dire ct connection to the DC supply branch 
circuit. It should only be connected to a po wer distribution unit (PDU) that provides an 
independent overcurrent-protected output for each DC power supply. Each output 
overcurrent-protected device in the PDU must  be suitable for interrupting fault current 
available from the DC power source an d must be rated no more than 50A. 
•   This power supply is designed to be connecte d only to a DC power source that can be 
classified as SELV or TNV, in accordance  with applicable national requirements for 
Information Technology Equipment and Te lecommunications Equipment. Generally, 
these requirements are based on the In ternational Standard for Information 
Technology Equipment, IEC 60950, and/or  the European Telecommunication Standard 
ETS 300 132-2. The DC source is to have one pole (Neutral/Return) reliably connected 
to earth ground in accordance  with local/regional electric codes and/or regulations.  
•   The green/yellow lead of the power cable assembly must be connected to a suitable 
ground/earth terminal. This terminal must be connected to a suitable building 
ground/earth terminal in accordance with  local/regional electric codes/regulations. 
Do not rely on the rack or cabinet ch assis to provide adequate ground/earth 
continuity.

  WARNING:  To reduce the risk of personal  injury or damage to the equipment, the 
installation of power supplies should be perf ormed only by individuals who are qualified 
in servicing server equipment and trained to  deal with products capable of producing 
hazardous energy levels.   
  WARNING:  To reduce the risk of personal  injury from hot surfaces, observe the thermal 
labels on each power supply or module.  
  WARNING:  To reduce the risk of injury from  electric shock hazards, do not open power 
supplies. Refer all maintenance, upgrades , and servicing to qualified personnel. 
  CAUTION:   Do not run the server with one AC power supply and one DC power supply installed. 
  CAUTION:   Electrostatic discharge (ESD) can damage electronic components. Be sure that you are properly 
grounded (earthed) before beginning any installation procedure. 
To install the component: 
1. Remove the power supply blank. 
 
  WARNING:  To reduce the risk of electric  shock or damage to the equipment, do not 
connect the power cord to the power su pply until the power supply is installed.
