DIMM slots

DIMMs are secured by white or yellow latches.

White latches indicate the memory is connected to CPU 1.

Yellow latches indicate the memory is connected to CPU 2.

3

CPU socket 1 (Populated)

CPU 1 connects to DIMMs with a white DIMM latch.

This CPU socket must always be populated. If your server will run with only one CPU, the CPU must be installed in this socket.

4

CPU socket 2 (Unpopulated)

CPU 2 connects to DIMMs with a yellow DIMM latch.

This CPU socket is populated in a normal, dual-CPU deployment. If your server will run with only one CPU, the CPU must be installed CPU socket 1.

Any replacement CPUs are shipped in a separate shipping package which contains the CPU, CPU carrier, and a fixture.

To replace a CPU, you will remove the CPU from the fixture, then install the CPU into the CPU socket on the server motherboard. See the following topics:

Required Tools for CPU and Heatsink Replacement

The following tools are required for replacing server CPUs and heatsinks:

  • ESD-safe workspace, such as a rubberized mat, where you can safely put components that are out of the server.

  • ESD gloves

  • T30 Torx driver

  • M6 CPU Fixture (UCS-CPUATI-3=)

  • Cleaning Kit (UCSX-HSCK=)

  • Thermal Grease (UCS-CPU-TIM=)


Note

Blades can ship with either a dual CPU or single CPU configuration. If your blade is a single CPU config, the unpopulated CPU socket will ship with a dust cover.

  • If your blade ships with a dual CPU config, no CPU dust cover is shipped.

  • If you have a dual CPU config, and you are removing one CPU to run as a single-CPU blade, you will need to install a CPU dust cover on the unpopulated CPU socket. In this situation, you will need to order the CPU dust cover, which is available directly from the dust cover manufacturer. Use the following information to order dust covers:

    • Manufacturer: Foxconn Interconnect Tech (FIT)

    • Dust Cover: WNMBD00-1NNK0-EH

    • Go the Manufacturer website.

Removing CPUs and Heatsinks

Use the following procedure to remove an installed CPU and heatsink from the blade server. With this procedure, you will remove the CPU from the motherboard, disassemble individual components, then place the CPU and heatsink into the fixture that came with the CPU.

Procedure

Step 1

Detach the CPU and heatsink (the CPU assembly) from the CPU socket.

  1. Using the T30 Torx driver, loosen all the securing nuts.

  2. Push the rotating wires towards each other to move them to the unlocked position.

    Caution

     

    Make sure that the rotating wires are as far inward as possible. When fully unlocked, the bottom of the rotating wire disengages and allows the removal of the CPU assembly. If the rotating wires are not fully in the unlocked position, you can feel resistance when attempting to remove the CPU assembly.

Step 2

Remove the CPU assembly from the motherboard.

  1. Grasp the heatsink along the edge of the fins and lift the CPU assembly off of the motherboard.

    Caution

     
    While lifting the CPU assembly, make sure not to bend the heatsink fins. Also, if you feel any resistance when lifting the CPU assembly, verify that the rotating wires are completely in the unlocked position.

  2. Put the CPU assembly on a rubberized mat or other ESD-safe work surface.

    When placing the CPU on the work surface, the heatsink label should be facing up. Do not rotate the CPU assembly upside down.

  3. Ensure that the heatsink sits level on the work surface.

Step 3

Attach a CPU dust cover to the CPU socket.

The dust cover is orderable directly from the manufacturer. For more information, see Required Tools for CPU and Heatsink Replacement.

  1. Align the posts on the CPU bolstering plate with the cutouts at the corners of the dust cover.

  2. Lower the dust cover and simultaneously press down on the edges until it snaps into place over the CPU socket.

    Caution

     

    Do not press down in the center of the dust cover!


Step 4

Detach the CPU from the CPU carrier by disengaging CPU clips and using the TIM breaker.

  1. Turn the CPU assembly upside down, so that the heatsink is pointing down.

    This step enables access to the CPU securing clips.

  2. Gently lift the TIM breaker (1 in the following illustration) in a 90-degree upward arc to partially disengage the CPU clips on this end of the CPU carrier.

  3. Lower the TIM breaker into the u-shaped securing clip to allow easier access to the CPU carrier.

    Note

     

    Make sure that the TIM breaker is completely seated in the securing clip.

  4. Gently pull up on the outer edge of the CPU carrier (2) so that you can disengage the second pair of CPU clips near both ends of the TIM breaker.

    Caution

     

    Be careful when flexing the CPU carrier! If you apply too much force you can damage the CPU carrier. Flex the carrier only enough to release the CPU clips. Make sure to watch the clips while performing this step so that you can see when they disengage from the CPU carrier.

  5. Gently pull up on the outer edge of the CPU carrier so that you can disengage the pair of CPU clips (3 in the following illustration) which are opposite the TIM breaker.

  6. Grasp the CPU carrier along the short edges and lift it straight up to remove it from the heatsink.

Step 5

Transfer the CPU and carrier to the fixture.

  1. When all the CPU clips are disengaged, grasp the carrier and lift it and the CPU to detach them from the heatsink.

    Note

     

    If the carrier and CPU do not lift off of the heatsink, attempt to disengage the CPU clips again.

  2. Flip the CPU and carrier right-side up so that the words PRESS are visible.

  3. Align the posts on the fixture and the pin 1 locations on the CPU carrier and the fixture (1 in the following illustration).

  4. Lower the CPU and CPU carrier onto the fixture.



Step 6

Use the provided cleaning kit (UCSX-HSCK) to remove all of the thermal interface barrier (thermal grease) from the CPU, CPU carrier, and heatsink.

Important

 

Make sure to use only the Cisco-provided cleaning kit, and make sure that no thermal grease is left on any surfaces, corners, or crevices. The CPU, CPU carrier, and heatsink must be completely clean.

What to do next

Choose the appropriate option:

  • If you will be installing a CPU, go to Installing CPUs and Heatsinks.

  • If you will not be installing a CPU, verify that a CPU socket cover is installed. This option is valid only for CPU socket 2 because CPU socket 1 must always be populated in a runtime deployment.

Installing CPUs and Heatsinks

Use this procedure to install a CPU if you have removed one, or if you are installing a CPU in an empty CPU socket. To install the CPU, you will move the CPU to the fixture, then attach the CPU assembly to the CPU socket on the server mother board.

Procedure

Step 1

Remove the CPU socket dust cover on the server motherboard.

  1. Push the two vertical tabs inward to disengage the dust cover.

  2. While holding the tabs in, lift the dust cover up to remove it.

  3. Store the dust cover for future use.

    Caution

     

    Do not leave an empty CPU socket uncovered. If a CPU socket does not contain a CPU, you must install a CPU dust cover.

Step 2

Grasp the CPU fixture on the edges labeled PRESS, lift it out of the tray, and place the CPU assembly on an ESD-safe work surface.

Step 3

Apply new TIM.

Note

 
The heatsink must have new TIM on the heatsink-to-CPU surface to ensure proper cooling and performance.

  • If you are installing a new heatsink, it is shipped with a pre-applied pad of TIM. Go to step 4.

  • If you are reusing a heatsink, you must remove the old TIM from the heatsink and then apply new TIM to the CPU surface from the supplied syringe. Continue with step a below.

  1. Apply the Bottle #1 cleaning solution that is included with the heatsink cleaning kit (UCSX-HSCK=), as well as the spare CPU package, to the old TIM on the heatsink and let it soak for a least 15 seconds.

  2. Wipe all of the TIM off the heatsink using the soft cloth that is included with the heatsink cleaning kit. Be careful to avoid scratching the heatsink surface.

  3. Completely clean the bottom surface of the heatsink using Bottle #2 to prepare the heatsink for installation.

  4. Using the syringe of TIM provided with the new CPU (UCS-CPU-TIM=), apply 1.5 cubic centimeters (1.5 ml) of thermal interface material to the top of the CPU. Use the pattern shown in the following figure to ensure even coverage.

    Figure 5. Thermal Interface Material Application Pattern

    Caution

     

    Use only the correct heatsink for your CPU. CPU 1 uses heatsink UCSB-HS-M6-R and CPU 2 uses heatsink UCSB-HS-M6-F.

Step 4

Attach the heatsink to the CPU fixture.

  1. Grasp the heatsink by the fins (1, in the following illustration), align pin 1 location of the heatsink with the pin 1 location on the CPU fixture (2), then lower the heatsink onto the CPU fixture.

    The heatsink is correctly oriented when the embossed triangle points to the CPU pin 1 location, as shown.

    Caution

     

    Make sure the rotating wires are in the unlocked position so that the feet of the wires do not impede installing the heatsink.

Step 5

Install the CPU assembly onto the CPU motherboard socket.

  1. Push the rotating wires inward to the unlocked position so that they do not obstruct installation.



  2. Grasp the heatsink by the fins (1 in the following illustration), align the pin 1 location on the heatsink with the pin 1 location on the CPU socket (2), then seat the heatsink onto the CPU socket.

    The heatsink is correctly oriented when the embossed triangle points to the CPU pin 1 location, as shown.

    Caution

     

    Make sure the rotating wires are in the unlocked position so that the feet of the wires do not impede installing the heatsink.

  3. Push the rotating wires away from each other to lock the CPU assembly into the CPU socket (1 in the following illustration).

    Caution

     

    Make sure that you close the rotating wires completely before using the Torx driver to tighten the securing nuts.

  4. Set the T30 Torx driver to 12 in-lb of torque and tighten the 4 securing nuts in a diagonal pattern to secure the CPU to the motherboard (2). You can start with any nut, but make sure to tighten the securing nuts in a diagonal pattern.

Replacing Memory DIMMs

To replace a memory DIMM, see the following topics:

DIMM Slot Identifiers

This blade server contains 32 DIMM slots—16 per CPU

To assist with identification, each DIMM slot displays its memory processor and slot ID on the motherboard. For example, P1 A1 indicates slot A1 for processor 1.

Also, you can further identify which DIMM slot connects to which CPU by the latch color for the DIMM slot.

  • All DIMM slots with white latches are connected to CPU 1.

  • All DIMM slots with yellow latches are connected to CPU 2.

  • DIMM slots with white and yellow latches are oriented 180 degrees from each other due to the keying in the slot. While installing DIMMs in sockets with white latches, you will need to rotate the DIMMs 180 degrees.


    Caution

    If you feel resistance while seating a DIMM into its socket, do not force the DIMM or you risk damaging the DIMM or the slot. Check the keying on the slot and verify it against the keying on the bottom of the DIMM. When the DIMM's and slot's keys are aligned, reinstall the DIMM.

For each CPU, each set of 16 DIMMs is arranged into 8 channels, where each channel has two DIMMs. Each DIMM slot is numbered 1 or 2, and each DIMM slot 1 is blue and each DIMM slot 2 is black. Each channel is identified by two pairs of letters and numbers where the first pair indicates the processor, and the second pair indicates the memory channel and slot in the channel.

  • Channels for CPU 1 are P1 A1 and A2, P1 B1 and B2, P1 C1 and C2, P1 D1 and D2, P1 E1 and E2, P1 F1 and F2, P1 G1 and G2, P1 H1 and H2.

  • Channels for CPU 2 are P2 A1 and A2, P2 B1 and B2, P2 C1 and C2, P2 D1 and D2, P2 E1 and E2, P2 F1 and F2, P2 G1 and G2, P2 H1 and H2.

The following figure shows how DIMMs and channels are physically laid out and numbered. DIMM channel and slot IDs for CPU 1 are shown in blue text, and DIMM channel and slot IDs for CPU 2 are shown in black text.

Memory Population Guidelines

The following is a partial list of memory usage and population guidelines. For detailed information about memory usage and population, download the Cisco UCS C220/C240/B200 M6 Memory Guide.


Caution

Only Cisco memory is supported. Third-party DIMMs are not tested or supported.

Memory Population Order

The Cisco UCS B200 M6 blade has two memory options, DIMMs only or DIMMs plus Intel Optane PMem 200 series memory.

Memory slots are color coded, blue and black. The color-coded channel population order is blue slots first, then black.

For optimal performance, populate DIMMs in the order shown in the following table, depending on the number of CPUs and the number of DIMMs per CPU. If your server has two CPUs, balance DIMMs evenly across the two CPUs as shown in the table.


Note

The table below lists recommended configurations. Using 3, 5, 7, 9, 10, 11, or 13-15 DIMMs per CPU is not recommended. Other configurations will result in reduced performance.

The following table shows the memory population order for DDR4 DIMMs.

DIMM Slot Keying Consideration

DIMM slots with white and yellow latches are oriented 180 degrees from each other. In the center memory column, slots with white and yellow latches are next to each other, so the DIMM orientation must change depending on which slots you are populating with DIMMs.

Each DIMM slot has a key that fits a notch in the DIMM, and because of the 180-degree orientation difference, the DIMM slot keys are at a different location for DIMM slots with white and yellow latches.

1 DIMM slot key
2 Example of DIMM slot key location difference

When installing a DIMM, always make sure that the key in the DIMM slot lines up with the notch in the DIMM.


Caution

If you feel resistance while seating a DIMM into its socket, do not force the DIMM or you risk damaging the DIMM or the slot. Check the keying on the slot and verify it against the keying on the bottom of the DIMM. When the slot's key and the DIMM's notch are aligned, reinstall the DIMM.

Removing DIMMs or DIMM Blanks

The server top cover must be removed to access the DIMM slots.

To remove a DIMM or a DIMM blank (UCS-DIMM-BLK=) from a slot on the blade server, follow these steps.

Procedure

Step 1

Grasp each DIMM baffle and lift it off of the blade.

Each DIMM baffle is fitted onto a standoff, so you need to pull straight up far enough to disconnect the baffle from the standoff.

Note

 

You will find it helpful to remember each DIMM baffle's location on the blade.

Step 2

Open both DIMM connector latches by pushing them away from each other.

Step 3

Grasp each end of the DIMM or blank and lift it out of the socket.

Figure 6. Removing a DIMM or DIMM Blank

Step 4

If you are removing a DIMM blank and installing a DIMM, keep the DIMM blank in safe place.

Note

 

If you will not be installing a DIMM, you must install a DIMM blank. Do not operate the server with an empty DIMM slot.

What to do next

Go to Installing DIMMs or DIMM Blanks.

Installing DIMMs or DIMM Blanks

To install a DIMM or a DIMM blank (UCS-DIMM-BLK=) into a slot on the blade server, follow these steps.


Caution

White and yellow DIMM latches are oriented 180 degrees from other. Check the keying on the DIMM and its slot to verify that they are properly aligned before installing the DIMM. See DIMM Slot Identifiers.

Procedure

Step 1

Open both DIMM connector latches.

Step 2

Insert the DIMM and press evenly on both ends until it clicks into place in its slot.

Note

 

Ensure that the notch in the DIMM aligns with the key in the slot. If the notch is misaligned, it is possible to damage the DIMM, the slot, or both.

Step 3

Press the DIMM connector latches inward slightly to seat the DIMM or blank fully.

Figure 7. Installing a DIMM or DIMM Blank

Step 4

Populate all slots with a DIMM or DIMM blank.

A slot cannot be empty, so make sure all slots have either a DIMM or DIMM blank before reinserting the blade.

Step 5

Install each DIMM baffle.

  1. Orient each DIMM baffle as shown.

  2. Align each DIMM baffle so that the circle on the top of the DIMM baffle lines up with the standoff on the blade.

    DIMM baffles are keyed so that they can be installed one way only. If a baffle does not install, remove both baffles, and try to install them in the opposite location.

  3. Holding the DIMM baffle level, lower the baffle and press down to seat the baffle onto the standoff and the two feet onto the blade.

  4. (Optional) Attach the top cover and return the blade to service.

Memory Performance

When considering the memory configuration of the blade server, there are several things to consider. For example:

  • When mixing DIMMs of different densities (capacities), the highest density DIMM goes in slot 1 then in descending density.

  • Besides DIMM population and choice, the selected CPU(s) can have some effect on performance.

Memory Mirroring and RAS

The Intel CPUs within the blade server support DDR4 memory mirroring only in 8 and 16 DIMM configurations on each CPU. If memory mirroring is used, DRAM size is reduced by 50 percent for reasons of reliability.

Replacing a Virtual Interface Card

Step 2

Orient the drive so that the gasket is facing up.

Also, you can check the label on the faceplate to verify that the drive is oriented correctly.

Step 3

Holding the drive level, align it with the empty drive bay, then slide the drive in until it no longer moves.

Replacing a Front Mezzanine Drive Blank

The Cisco UCS B200 M6 blade has two drive bays on the blade faceplate. A minimum of one drive must be installed.

A front mezzanine drive blank (UCSB-FBLK-M6) must be installed in any empty drive bay. Do not operate the blade with an empty drive bay.

To replace a front mezzanine drive blank, use the following procedures:

Removing a Drive Blank

Drive blanks are accessible from the front of the blade. Use this procedure to remove a drive blank (UCSB-FBLK-M6).


Note

Do not operate the blade with an empty drive bay. Always install a drive blank in a drive bay that does not have a drive installed.

Procedure

Step 1

Pinch the two retaining tabs towards each other.

Step 2

While holding the retaining tabs inward, pull the drive blank out of the drive bay.

What to do next

Choose the appropriate option:

Installing a Drive Blank

The blade has two drive bays accessible from the front of the blade. In a minimum configuration, the blade has one drive installed and one empty drive bay. Any empty drive bay must have a drive blank installed (UCSB-FBLK-M6). Do not operate the blade without a drive blank installed in an empty drive bay.

Use this procedure to install a drive blank.

Procedure

Step 1

Grasp the drive blank by the retaining tabs.

Step 2

Holding the drive blank level, align it with the empty drive bay and slide it into the bay until it no longer moves.

Removing the Trusted Platform Module (TPM)

The TPM module is attached to the printed circuit board assembly (PCBA). You must disconnect the TPM module from the PCBA before recycling the PCBA. The TPM module is secured to a threaded standoff by a tamper-resistant screw. If you do not have the correct tool for the screw, you can use a pair of pliers to remove the screw.

Note

For Recyclers Only! This procedure is not a standard field-service option. This procedure is for recyclers who will be reclaiming the electronics for proper disposal to comply with local eco design and e-waste regulations.

To remove the Trusted Platform Module (TPM), the following requirements must be met for the server:

  • It must be disconnected from facility power.

  • It must be removed from the equipment rack.

Procedure

Step 1

Locate the TPM module.

Step 2

Using a 6 mm slotted screwdriver or pliers, loosen the TPM screw and remove the TPM from the motherboard.

Step 3

Dispose of the TPM properly.

What to do next

Remove and dispose of the PCB Assembly. See Recycling the PCB Assembly (PCBA).

Recycling the PCB Assembly (PCBA)

Each blade server has a PCBA that is connected to the blade server's faceplate and sheet metal tray. You must disconnect the PCBA from the blade server's faceplate and tray to recycle the PCBA. Each blade server is attached to the faceplate and tray by the following:

  • Faceplate: Two M3 3mm screws.

  • Tray:

    • Five M3 screws

    • Seven hex nut standoffs

You will need to recycle the PCBA for each blade server.
