3. Gently press around the periphery of the shroud until it engages with the external tabs and snaps into place.
   
   

Power Supplies

Your system supports one or two power supplies rated at an output of 670 W. If only one power supply is installed, it must be installed in the left power supply bay (bay 1). If two power supplies are installed, the second power supply serves as a redundant, hot-plug power source.

NOTICE: In a non-redundant configuration, the power supply blank must be installed in the unoccupied power supply bay to ensure proper system cooling. See Installing the Power Supply Blank.

Removing a Power Supply

NOTICE: The system requires one power supply for the system to operate normally. The system is in the redundant mode when two power supplies are installed and both power supplies are connected to an AC power source. Remove and replace only one power supply at a time in a system that is powered on. Operating the system with only one power supply installed and without a power supply blank installed for extended periods of time can cause the system to overheat.

NOTICE: If only one power supply is installed, it must be installed in the left power supply bay (1).

NOTICE: If you connect the system to a power source in the range of 120 to 220 VAC, and if two power supplies are installed, the second power supply serves as a redundant, hot-plug power source.

NOTE: On your rack system, you may have to unlatch and lift the cable management arm if it interferes with power supply removal. For information about the cable management arm, see the system's Rack Installation Guide.

1. If your system has a single power supply, turn off the system and all attached peripherals. For a redundant system, you can leave the system running and proceed to the next step.
   
   
2. Disconnect the power cable from the power source.
   
   
3. Disconnect the power cable from the power supply and remove the cable from the cable retention bracket.
   
   

NOTICE: On a rack system, you may need to temporarily unlatch and lift the cable management arm. For information about the cable management arm, see the system's Rack Installation Guide.

Configuring the Boot Device

If you plan to boot the system from a hard drive, the drive must be attached to the primary (or boot) controller. The device that the system boots from is determined by the boot order specified in the System Setup program.

The System Setup program provides options that the system uses to scan for installed boot devices. See Using the System Setup Program for information about the System Setup program.

Configuring the Boot Drive

The drive or device from which the system boots is determined by the boot order specified in the System Setup program. See Using the System Setup Program for information about the System Setup program.

System Memory

You can upgrade your system memory to a maximum of 32 GB by installing 533-MHz or 667-MHz fully buffered (FB) DDR II memory modules (DIMMs) in sets of 256-MB, 512-MB, 1-GB, 2-GB, or 4-GB modules. The eight memory sockets are located on the system board under the memory cooling shroud.You can purchase memory upgrade kits from Dell.

NOTICE: If you remove your original memory modules from the system during a memory upgrade, keep them separate from any new memory modules that you may have, even if you purchased the new memory modules from Dell. Use only 533-MHz or 667-MHz DDR II fully buffered DIMMS (FBDs).

The memory module sockets are divided into two equal branches (0 and 1). Each branch consists of two channels:

• Channel 0 and channel 1 are in branch 0.
  
  
• Channel 2 and channel 3 are in branch 1.
  
  

Each channel consists of two memory module sockets:

• Channel 0 contains DIMM_1, DIMM_5.
  
  
• Channel 1 contains DIMM _2, DIMM_6.
  
  
• Channel 2 contains DIMM_3, DIMM_7.
  
  
• Channel 3 contains DIMM _4, DIMM _8.
  
  

The first DIMM socket of each channel has white release tabs.

General Memory Module Installation Guidelines

To ensure optimal performance of your system, observe the following guidelines when configuring your system memory.

• Use only qualified FBDs. FBDs can be either single-ranked or dual-ranked. FBDs marked with a 1R are single-ranked and modules marked with a 2R are dual-ranked.
  
  
• A minimum of two identical FBDs must be installed.
  
  
• DIMM sockets must be populated by lowest number first.
  
  
• Memory modules must be installed in pairs of matched memory size, speed, and technology, and the total number of memory modules in the configuration must total two, four, or eight. For best system performance, all four, or eight memory modules should be identical in size, speed, and technology.
  
  
• Memory sparing and memory mirroring require eight memory, and all memory modules must be of identical memory size, speed, and technology.
  
  
• Memory sparing and memory mirroring cannot be implemented at the same time.
  
  

Non-Optimal Memory Configurations

System performance can be affected if your memory configuration does not conform to the preceding installation guidelines. Your system may issue an error message during startup stating that your memory configuration is non-optimal.

Memory Sparing Support

The system supports memory sparing if eight identical memory modules are installed in the system. The memory sparing feature must be enabled in the System Setup program and can be used only if memory mirroring is not enabled.(See Using the System Setup Program.)

Memory sparing allocates four ranks of DIMM memory to the spare bank. These four ranks consist of the first rank of memory in DIMM sockets 1 through 4. For single-rank DIMMs, the entire capacity of the four DIMMs is allocated to sparing whereas for dual-rank DIMMs, only half of the four-DIMM capacity is allocated to sparing. Table 3-1 shows how memory sparing splits the available and spared memory in each of the single- and dual-ranked memory module combinations.

Table 3-1. Memory Sparing Configurations 

Memory Mirroring Support

The system supports memory mirroring if eight identical memory modules are installed in the system. Mirroring must be enabled in the System Setup program and can be used only if memory sparing is not enabled. (See Using the System Setup Program.) In a mirrored configuration, the total available system memory is one-half of the total installed memory.

Installing Memory Modules

CAUTION: Only trained service technicians are authorized to remove the system cover and access any of the components inside the system. See your Product Information Guide for complete information about safety precautions, working inside the computer, and protecting against electrostatic discharge.

CAUTION: The memory modules are hot to the touch for some time after the system has been powered down. Allow time for the memory modules to cool before handling them. Handle the memory modules by the card edges and avoid touching the components on the memory module.

Hard Drives

This subsection describes how to install and configure SAS or SATA hard drives in the system's internal hard-drive bays. Your system features the option of two 3.5-inch (SAS/SATA) internal hard-drive bays or four 2.5-inch (SAS only) internal hard-drive bays that accommodate up to either two or four hard drives. All drives connect to the system board through one of two optional backplane boards.

NOTE: Depending on the hard drive configuration you ordered, your hard drive(s) may come with a drive interposer that allows your SATA drive to attach to the SAS connector on the backplane.

Before You Begin

Hard drives are supplied in special hot-pluggable drive carriers that fit in the hard-drive bays. Depending on your configuration, you received one of the following two drive carrier types:

• SATA drive carrier — Usable only with a SATA hard drive.
  
  
• SATAu drive carrier — Usable with either a SAS hard drive or a SATA hard drive with a universal interposer card. The interposer card provides enhanced functionality that makes the SATA hard drive usable in some storage systems.
  
  

NOTICE: Before you attempt to remove or install a drive while the system is running, see the documentation for the optional SAS RAID daughter card to ensure that the host adapter is configured correctly to support hot-pluggable drive removal and insertion.

NOTE: It is recommended that you use only drives that have been tested and approved for use with the SAS backplane board.

You may need to use different programs than those provided with the operating system to partition and format SAS or SATA hard drives.

NOTICE: Do not turn off or reboot your system while the drive is being formatted. Doing so can cause a drive failure.

When you format a high-capacity hard drive, allow enough time for the formatting to be completed. Long format times for these drives are normal. A 9-GB hard drive, for example, can take up to 2.5 hours to format.

Removing a Drive Blank

NOTICE: To maintain proper system cooling, all empty hard-drive bays must have drive blanks installed. If you remove a hard-drive carrier from the system and do not reinstall it, you must replace the carrier with a drive blank.

The process for removing a drive blank depends on whether your system is configured with 3.5-inch or 2.5-inch hard drives.

For 3.5-inch hard drive configurations:

1. Remove the front bezel, if attached. See Removing and Replacing the Front Bezel.
   
   
2. Insert your finger under the shrouded end of the blank and press in on the latch to eject the blank outward from the bay.
   
   
3. Pry the ends of the blank outward until the blank is free.
   
   

For 2.5-inch hard drive configurations, remove the blank as you would the 2.5-inch hard drive carrier:

1. Remove the front bezel, if attached. See Replacing the System Battery.
   
   
2. Open the drive blank release handle to release the blank. See Figure 3-18.
   
   
3. Slide the drive blank out until it is free of the drive bay.
   
   

Installing a Drive Blank

The process for installing a drive blank depends on whether your system is configured with 3.5-inch or 2.5-inch hard drives.

For 3.5-inch hard drive configurations, the drive blank is keyed to ensure correct insertion into the drive bay. To install a 3.5-inch drive blank, insert the blank into the drive bay rotating in with the key side first, and press evenly on the ends of the blank until it is fully inserted and latched.

For 2.5-inch hard drive configurations, install the hard drive blank as a 2.5-inch hard drive carrier:

1. Remove the front bezel, if attached. See Removing and Replacing the Front Bezel.
   
   
2. Open the handle on the hard-drive blank.
   
   
3. Insert the hard-drive blank into the drive bay until it is fully seated.
   
   
4. Close the handle to lock the blank in place.
   
   
5. Replace the front bezel, if it was removed in step 1.
   
   

Installing a Hot-Plug Hard Drive

NOTICE: When installing a hard drive, ensure that the adjacent drives are fully installed. Inserting a hard-drive carrier and attempting to lock its handle next to a partially installed carrier can damage the partially installed carrier's shield spring and make it unusable.

NOTICE: Not all operating systems support hot-plug drive installation. See the documentation supplied with your operating system.

1. Remove the front bezel if attached. See Removing and Replacing the Front Bezel.
   
   
2. If a drive blank is present in the bay, remove it. See Removing a Drive Blank.
   
   
3. Install the hot-plug hard drive.
   
   
   1. Open the hard-drive carrier handle. See Figure 3-18.
