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 up to six 3.5-inch hard drives, or eight 2.5-inch hard drives. All drives connect to the system board through one of three optional SAS backplane boards. See SAS Backplane Board Connectors for information on these backplane options.

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 attempting to remove or install a drive while the system is running, see the documentation for the optional SAS RAID controller daughter card to ensure that the host adapter is configured correctly to support hot-plug 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:

Remove the front bezel, if attached. See Removing the Front Bezel.
Insert your finger under the shrouded end of the blank and press in on the latch to eject the blank outward from the bay.
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:

Remove the front bezel, if attached. See Removing the Front Bezel.
Open the drive blank release handle to release the blank. See Figure 3-4.
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 and rotate in the keyed side of the blank into the drive bay and press evenly on the other end 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:

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

Removing a Hot-Plug Hard Drive

Remove the front bezel, if attached. See Removing the Front Bezel.
From the RAID management software, prepare the drive for removal and wait until the hard-drive indicators on the drive carrier signal that the drive can be removed safely. See your SAS RAID controller documentation for information about hot-plug drive removal.

If the drive has been online, the green activity/fault indicator will flash as the drive is powered down. When both drive indicators are off, the drive is ready for removal.

Open the drive carrier release handle to release the drive. See Figure 3-4.
Slide the hard drive out until it is free of the drive bay.
If you do not replace the hard drive, insert a drive blank in the vacated drive bay. See Installing a Drive Blank.

NOTICE: To maintain proper system cooling, all empty hard-drive bays must have drive blanks installed.

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.

Remove the front bezel, if attached. See Removing the Front Bezel.
If a drive blank is present in the bay, remove it. See Removing a Drive Blank.

Power Supplies

Your system supports one or two power supplies rated at an output of 750 W. If only one power supply is installed, it must be installed in the left power supply bay (1). If two power supplies are installed, the second power supply serves as a redundant, hot-plug power source.

NOTICE: To ensure proper system cooling, the power supply blank must be installed on the unoccupied power supply bay in a non-redundant configuration. 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.

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.
Disconnect the power cable from the power source.
Disconnect the power cable from the power supply and remove the cable from the cable retention bracket.
Release the locking tab on the left side of the power supply by pressing in toward the right, and rotate the power-supply handle up until the power supply is released from the chassis. See Figure 3-8.

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.

Expansion Cards

The system is available with either a PCI-X or a PCI Express (PCIe) left riser board option. The PCI-X left riser board provides two PCI-X 64-bit/133-MHz expansion slots, while the PCIe left riser board provides one PCIe x8-lane expansion slot and one PCIe x4-lane expansion slot. The half-height center riser board provided with both PCI-X and PCIe left riser board options features one PCIe x8-lane expansion slot. The three expansion card slots are on separate buses.

Expansion Card Installation Guidelines

To identify expansion slots, see Expansion-Card Riser-Board Components and PCI Buses.

NOTE: The expansion-card slots are not hot-pluggable.

NOTE: Although the PCIe x4-lane expansion slot on the PCIe left riser option is physically a PCIe x8 connector, it functions only as a PCIe x4-lane slot.

NOTE: Slot 1 on the central riser supports half-length expansion cards only. Slots 2 and 3 on the left riser support full-length expansion cards.

NOTE: Your system supports up to two RAID expansion cards to manage external storage.

System Memory

You can upgrade your system memory to a maximum of 32 GB by installing 533MHz or 667MHz fully buffered (FB) DDR II memory modules in sets of 256-MB, 512-MB, 1-GB, 2-GB, or 4-GB. The eight memory sockets are located on the system board under the cooling shroud adjacent to the power supply bays. See Figure 6-2. 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 FB-DIMMs.

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 DIMM 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 Fully-Buffered DIMMs (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 installed.
DIMM sockets must be populated by lowest number first.
FBDs must be installed in pairs of matched memory size, speed, and technology, and the total number of FBDs in the configuration must total two, four, or eight. For best system performance, all four, or eight FBDs should be identical memory size, speed, and technology.
Memory sparing and memory mirroring require eight FBDs, and all FBDs 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.

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 3-2 shows how memory sparing splits the available and spared memory in each of the single- and dual-ranked memory module combinations.

Table 3-2. Memory Sparing Configurations

DIMMs	Size/Type	Total Memory	Available	Spare
8	256-MB single-rank	2 GB	1 GB	1 GB
	512-MB single-rank	4 GB	2 GB	2 GB
	1-GB single-rank	8 GB	4 GB	4 GB
	2-GB single-rank	16 GB	8 GB	8 GB
	2-GB dual-rank	16 GB	12 GB	4 GB
	4-GB dual-rank	32 GB	24 GB	8 GB

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. In a mirrored configuration, the total available system memory is one-half of the total installed memory.

Installing Memory Modules

Turn off the system, including any attached peripherals, and disconnect the system from the electrical outlet.
Open the system. See Opening the System.
Remove the memory cooling shroud. See Removing the Cooling Shroud.

NOTICE: Never remove the memory cooling shroud without first powering down the system. Overheating of the system can develop quickly resulting in a shutdown of the system and the loss of data.

Locate the memory module sockets on the system board. See Figure 6-2.

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

Press the ejectors on the memory module socket down and out, as shown in Figure 3-27, to allow the memory module to be inserted into the socket.

alignment key

Align the memory module's edge connector with the alignment key on the memory module socket, and insert the memory module in the socket.

NOTE: The memory module socket has an alignment key that allows you to install the memory module in the socket in only one way.

Press down on the memory module with your thumbs while pulling up on the ejectors with your index fingers to lock the memory module into the socket.

When the memory module is properly seated in the socket, the ejectors on the memory module socket align with the ejectors on the other sockets that have memory modules installed.

Repeat step 3 through step 7 of this procedure to install the remaining memory modules.
Replace the memory cooling shroud. See Installing the Cooling Shroud.

NOTICE: Never operate your system with the memory cooling shroud removed. Overheating of the system can develop quickly resulting in a shutdown of the system and the loss of data.

Close the system. See Opening the System.
(Optional) Enter the System Setup program, and check the System Memory setting on the main System Setup screen. See Entering the System Setup Program.

The system should have already changed the value to reflect the newly installed memory.

If the value is incorrect, one or more of the memory modules may not be installed properly. Repeat step 2 through step 11 of this procedure, checking to ensure that the memory modules are firmly seated in their sockets.
Run the system memory test in the system diagnostics. See Running the System Diagnostics.

Removing Memory Modules

Turn off the system, including any attached peripherals, and disconnect the system from the electrical outlet.
Open the system. See Opening the System.
Remove the memory cooling shroud. See Removing the Cooling Shroud.

NOTICE: Never remove the memory cooling shroud without first powering down the system. Overheating of the system can develop quickly resulting in a shutdown of the system and the loss of data.

Locate the memory module sockets on the system board. See Figure 6-2.

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

Press down and out on the ejectors on each end of the socket until the memory module pops out of the socket. See Figure 3-27.
Replace the memory cooling shroud. See Installing the Cooling Shroud.

NOTICE: Never operate your system with the memory cooling shroud removed. Overheating of the system can develop quickly resulting in a shutdown of the system and the loss of data.
