Figure 36. Memory socket locations Memory channels are organized as follows: Table 37.
The system supports Flexible Memory Configuration, enabling the system to be configured and run in any valid chipset architectural configuration. The following are the recommended guidelines for installing memory modules: • • • • • • • • • • • • RDIMMs and LRDIMMs must not be mixed. x4 and x8 DRAM based memory modules can be mixed. For more information, see Mode-specific guidelines. Up to two RDIMMs can be populated per channel regardless of rank count.
channel) × 24 (memory modules) × 16 GB = 288 GB, and not 24 (memory modules) × 16 GB = 384 GB. This calculation changes based on if it is single rank sparing or multi rank sparing. For multi rank sparing, the multiplier changes to 1/2 (ranks/channel). NOTE: Memory sparing does not offer protection against a multi-bit uncorrectable error. Memory mirroring Memory mirroring offers the strongest memory module reliability mode, providing improved uncorrectable multi-bit failure protection.
Figure 37. Removing a memory module Next step Install the memory module. NOTE: For single processor systems, install processor/DIMM blank on CPU2 socket. Installing a memory module Prerequisites Follow the safety guidelines listed in Safety instructions.

NOTE: When two identical PSUs are installed, power supply redundancy (1+1 – with redundancy or 2+0 – without redundancy) is configured in system BIOS. In redundant mode, power is supplied to the system equally from both PSUs when Hot Spare is disabled. When Hot Spare is enabled, one of the PSUs is put into the sleep mode when system utilization is low in order to maximize efficiency. NOTE: If two PSUs are used, they must be of the same maximum output power.
Installing a power supply unit The procedure for installing AC and DC PSUs is identical. Prerequisites 1 Follow the safety guidelines listed in Safety instructions. 2 For systems that support redundant PSU, ensure that both the PSUs are of the same type and have the same maximum output power. NOTE: The maximum output power (shown in watts) is listed on the PSU label. Step Slide the PSU into the system until the PSU is fully seated and the release latch snaps into place. Figure 70.
Wiring instructions for a DC power supply unit Your system supports up to two –(48–60) V DC power supply units (PSUs). WARNING: For equipment using –(48–60) V DC power supply units (PSUs), a qualified electrician must perform all connections to DC power and to safety grounds. Do not attempt connecting to DC power or installing grounds yourself. All electrical wiring must comply with applicable local or national codes and practices.
Steps 1 Strip the insulation from the end of the green or yellow wire, exposing approximately 4.5 mm (0.175 inch) of copper wire. 2 Using a hand-crimping tool (Tyco Electronics, 58433-3 or equivalent), crimp the ring-tongue terminal (Jeeson Terminals Inc., R5-4SA or equivalent) to the green and yellow wire (safety ground wire). 3 Connect the safety ground wire to the grounding post on the back of the system by using a #6-32 nut equipped with a locking washer.

A BOSS card Introduction to BOSS card BOSS is a simple RAID solution card designed specifically for booting a server's operating system. The card supports up to two 6 Gbps M.2 SATA drives. The BOSS adapter card has a x8 connector using PCIe gen 2.0 x2 lanes, available only in the low-profile and half-height form factor. The BOSS modular card has a dedicated slot in blade servers. NOTE: There are no status LEDs on the BOSS card. Figure 80. Features of BOSS card 1 SATA drive connector (2) 3 80 mm M.
• XC640 • XC6420 • XC740xd • XC940 BOSS card features BOSS card supports the following features: • Foreign Import • SMART Info • Auto-Rebuild Foreign Import A virtual disk is considered foreign if it is not native to the adapter. • A virtual disk is considered native to the adapter if: – The virtual disk was created or imported on the adapter.
Removing the BOSS card About this task CAUTION: Many repairs may only be done by a certified service technician. You should only perform troubleshooting and simple repairs as authorized in your product documentation, or as directed by the online or telephone service and support team. Damage due to servicing that is not authorized by Dell is not covered by your warranty. Read and follow the safety instructions that are shipped with your product.
NOTE: It is recommended that you always use a static mat and static strap while working on components inside the system. 2 Open the system cover. 3 Remove the card. See Removing the BOSS card. 4 Loosen the screws and lift the retention straps that secure the M.2 SSD module on the BOSS card. 5 Pull the M.2 SSD module away from the BOSS card. Figure 82.

Figure 84. Installing the BOSS card 1 BOSS card 2 card connector on the system board Driver installation The BOSS card uses the native AHCI driver of the supported operating systems. Windows driver installation — Dell provides the Dell Update Package (DUP) to update drivers on systems running Windows Server 2012 R2 and newer operating system. DUP is an executable application that updates drivers for specific devices. DUP supports command line interface and silent execution.
Virtual disk not visible to operating system Issue: In RAID mode a virtual disk is not appearing for use by an operating system. Probable cause: Virtual disks will not be presented to the system if they are not native to the controller. Corrective action: Import the virtual disk using Hardware-Independent Imaging (HII). Drive failure Issue: An installed drive is not listed in the BOSS configuration utility. OpenManage reports Physical Disk offline state.
Probable cause: Working as designed, BIOS only allows booting from the first listed boot device (in this case, slot 0) per peripheral controller. This only occurs in legacy BIOS boot mode. Corrective action: Swap the drive in slot 1 to slot 0. CLI reports unsupported features Issue: Several commands, options, or other features listed by the Marvell CLI state that they are unsupported when run.
