• maximum supported DIMM frequency of the processors The system contains 24 memory sockets split into two sets of 12 sockets, one set per processor. Each 12-socket set is organized into four channels. In each channel, the release levers of the first socket are marked white, the second socket black, and the third socket green. NOTE: DIMMs in sockets A1 to A12 are assigned to processor 1 and DIMMs in sockets B1 to B12 are assigned to processor 2. Figure 17.
channel 2: slots B3, B7, and B11 channel 3: slots B4, B8, and B12 The following table shows the memory populations and operating frequencies for the supported configurations. DIMM Type DIMMs Populated/ Channel Operating Frequency (in MT/s) 1.5 V UDIMM ECC RDIMM 1.
• Memory modules of different sizes can be mixed provided that other memory population rules are followed (for example, 2 GB and 4 GB memory modules can be mixed). • Populate four DIMMs per processor (one DIMM per channel) at a time to maximize performance. • If memory modules with different speeds are installed, they will operate at the speed of the slowest installed memory module(s) or slower depending on system DIMM configuration.
the installed memory is used to mirror the active DIMMs. In the event of an uncorrectable error, the system will switch over to the mirrored copy. This ensures SDDC and multi-bit protection. Memory installation guidelines: • Memory modules must be identical in size, speed, and technology. • DIMMs installed in memory sockets with white release levers must be identical and similar rule applies for sockets with black and green release tabs.

Do not touch the bottom of the processor. Touch only the side edges of the processor.
CAUTION: Never remove the heat sink from a processor unless you intend to remove the processor. The heat sink is necessary to maintain proper thermal conditions. 5 Remove the heat sink/heat-sink blank and processor/processor blank, as applicable. NOTE: The procedure to remove the heat-sink blank or processor blank is similar to removing a heat-sink or processor. 6 Unpack the new processor. 7 Align the processor with the socket keys on the ZIF socket.
Hot Spare Feature Your system supports the Hot Spare feature that significantly reduces the power overhead associated with power supply redundancy. When the Hot Spare feature is enabled, a redundant power supply is switched to a sleep state. The active power supply supports 100% of the load, thus operating at higher efficiency. The redundant power supply in the sleep state monitors output voltage of the active power supply.

CAUTION: The system requires one power supply for normal operation. On power-redundant systems, remove and replace only one power supply at a time in a system that is powered on. NOTE: You may have to unlatch and lift the optional cable management arm if it interferes with power supply removal. For information about the cable management arm, see the system’s rack documentation. 1 Disconnect the power wires from the power source and the connector from the power supply you intend to remove.
NOTE: When installing, hot-swapping, or hot-adding a new power supply, allow several seconds for the system to recognize the power supply and determine its status. The power-supply status indicator turns green to signify that the power supply is functioning properly. Removing The Power Supply Blank CAUTION: To ensure proper system cooling, the power supply blank must be installed in the second power supply bay in a nonredundant configuration.
3 Remove the cooling shroud. 4 Locate the battery socket. CAUTION: To avoid damage to the battery connector, you must firmly support the connector while installing or removing a battery. 5 To remove the battery, support the battery connector by pressing down firmly on the positive side of the connector.

Damage due to servicing that is not authorized by Dell is not covered by your warranty. Read and follow the safety instructions that came with the product.
Troubleshooting External Connections Ensure that all external cables are securely attached to the external connectors on your system before troubleshooting any external devices. Troubleshooting The Video Subsystem 1 Check the system and power connections to the monitor. 2 Check the video interface cabling from the system to the monitor. 3 Run the appropriate diagnostic test. If the tests run successfully, the problem is not related to video hardware. If the tests fail, see Getting Help.
3 Check the appropriate indicator on the NIC connector: • If the link indicator does not light, check all cable connections. • If the activity indicator does not light, the network driver files might be damaged or missing. Remove and reinstall the drivers if applicable. See the NIC's documentation. • If applicable, change the autonegotiation setting. • Use another connector on the switch or hub. 4 Ensure that the appropriate drivers are installed and the protocols are bound.
Troubleshooting A Damaged System 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 came with the product.
Reseat the power supply by removing and reinstalling it. NOTE: After installing a power supply, allow several seconds for the system to recognize the power supply and to determine if it is working properly. If the problem persists, see Getting Help. Troubleshooting Cooling Problems CAUTION: Many repairs may only be done by a certified service technician.
9 Close the system. 10 Enter the System Setup and check the system memory setting. If the problem is not resolved, proceed with the next step. 11 Open the system. 12 If a diagnostic test or error message indicates a specific memory module as faulty, swap or replace the module with a known good memory module. 13 To troubleshoot an unspecified faulty memory module, replace the memory module in the first DIMM socket with a module of the same type and capacity.
NOTE: When an SD card failure occurs, the internal dual SD module controller notifies the system. On the next reboot, the system displays a message indicating the failure. 4 If the Internal SD Card Redundancy option is set to Disabled, replace the failed SD card with a new SD card. 5 If SD card 1 has failed, remove the card from SD card slot 1. If SD card 2 has failed, install a new SD card in SD card slot 2 and proceed to step 7.
If you cannot resolve the problem, see Getting Help. Troubleshooting A Hard Drive 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.
