13
Installing the Server
Installation Warnings and Guidelines
Warning To prevent the system from overheating, do not operate it in an area that exceeds the maximum recommended ambient temperature of: 35° C (95° F).
Statement 1047
Warning The plug-socket combination must be accessible at all times, because it serves as the main disconnecting device.
Statement 1019
Warning This product relies on the building’s installation for short-circuit (overcurrent) protection. Ensure that the protective device is rated not greater than: 250 V, 15 A.
Statement 1005
Warning Installation of the equipment must comply with local and national electrical codes.
Statement 1074
Warning This unit is intended for installation in restricted access areas. A restricted access area can be accessed only through the use of a special tool, lock, and key, or other means of security.
Statement 1017
Caution To ensure proper airflow it is necessary to rack the servers using rail kits. Physically placing the units on top of one another or “stacking” without the use of the rail kits blocks the air vents on top of the servers, which could result in overheating, higher fan speeds, and higher power consumption. We recommend that you mount your servers on rail kits when you are installing them into the rack because these rails provide the minimal spacing required between the servers. No additional spacing between the servers is required when you mount the units using rail kits.
Caution Avoid uninterruptible power supply (UPS) types that use ferroresonant technology. These UPS types can become unstable with systems such as the Cisco UCS, which can have substantial current draw fluctuations from fluctuating data traffic patterns.
When you are installing a server, use the following guidelines:
• Plan your site configuration and prepare the site before installing the server. See the Cisco UCS Site
Preparation Guide for the recommended site planning tasks.

23
Installing the Server
Setting Up the System With the Cisco IMC Configuration Utility
Step 2
Step 3
In this NIC mode, DHCP replies are returned to both the shared LOM ports and the Cisco card ports. If the system determines that the Cisco card connection is not getting its IP address from a Cisco UCS Manager system because the server is in standalone mode, further DHCP requests from the Cisco card are disabled. Use the Cisco Card
NIC mode if you want to connect to Cisco IMC through a Cisco card in standalone mode.
• Shared LOM —The 1-Gb/10-Gb Ethernet ports are used to access Cisco IMC. You must select either the
Active-Active or Active-standby NIC redundancy setting in the following step.
• Dedicated —The dedicated management port is used to access Cisco IMC. You must select the None NIC redundancy setting in the following step.
• Cisco Card —The ports on an installed Cisco UCS Virtual Interface Card (VIC) are used to access the Cisco IMC.
You must select either the Active-Active or Active-standby NIC redundancy setting in the following step.
See also the required VIC Slot setting below.
• VIC Slot —Only if you use the Cisco Card NIC mode, you must select this setting to match where your VIC is installed. The choices are Riser1, Riser2, or Flex-LOM (the mLOM slot).
• If you select Riser1, you must install the VIC in slot 1.
• If you select Riser2, you must install the VIC in slot 2.
• If you select Flex-LOM, you must install an mLOM-style VIC in the mLOM slot.
Set the NIC redundancy to your preference. This server has three possible NIC redundancy settings:
• None —The Ethernet ports operate independently and do not fail over if there is a problem. This setting can be used only with the Dedicated NIC mode.
• Active-standby —If an active Ethernet port fails, traffic fails over to a standby port. Shared LOM and Cisco Card modes can each use either Active-standby or Active-active settings.
• Active-active (default)—All Ethernet ports are utilized simultaneously. The Shared LOM EXT mode must use only this NIC redundancy setting. Shared LOM and Cisco Card modes can each use either Active-standby or
Active-active settings.
Choose whether to enable DHCP for dynamic network settings, or to enter static network settings.
Note Before you enable DHCP, you must preconfigure your DHCP server with the range of MAC addresses for this server. The MAC address is printed on a label on the rear of the server. This server has a range of six
MAC addresses assigned to Cisco IMC. The MAC address printed on the label is the beginning of the range of six contiguous MAC addresses.
The static IPv4 and IPv6 settings include the following:
• The Cisco IMC IP address.
For IPv6, valid values are 1 - 127.
• The gateway.
For IPv6, if you do not know the gateway, you can set it as none by entering :: (two colons).

Hot Swap vs Hot Plug
Some components can be removed and replaced without shutting down and removing power from the server.
This type of replacement has two varieties: hot-swap and hot-plug.
• Hot-swap replacement—You do not have to shut down the component in the software or operating system. This applies to the following components:
• SAS/SATA hard drives
• SAS/SATA solid state drives
• Cooling fan modules
• Power supplies (when redundant as 1+1)
• Hot-plug replacement—You must take the component offline before removing it for the following component:
• NVMe PCIe solid state drives
Removing and Replacing Components
Warning Blank faceplates and cover panels serve three important functions: they prevent exposure to hazardous voltages and currents inside the chassis; they contain electromagnetic interference (EMI) that might disrupt other equipment; and they direct the flow of cooling air through the chassis. Do not operate the system unless all cards, faceplates, front covers, and rear covers are in place.
Statement 1029
Caution When handling server components, handle them only by carrier edges and use an electrostatic discharge (ESD) wrist-strap or other grounding device to avoid damage.
Tip You can press the unit identification button on the front panel or rear panel to turn on a flashing, blue unit identification LED on both the front and rear panels of the server. This button allows you to locate the specific server that you are servicing when you go to the opposite side of the rack. You can also activate these LEDs remotely by using the Cisco IMC interface.

Replacing a Front-Loading NVMe SSD, on page 45
.
SAS/SATA Drive Population Guidelines
The server is orderable in two different versions, each with a different front panel/drive-backplane configuration.
• Cisco UCS C220 M6 SAS/SATA (UCSC-C225-M6S)—Small form-factor (SFF) drives, with 10-drive backplane. Supports up to 10 2.5-inch SAS/SATA drives.
Drive bay numbering is shown in the following figures.
Figure 17: Drive Bay Numbering
Observe these drive population guidelines for optimum performance:
• When populating drives, add drives to the lowest-numbered bays first.
• Keep an empty drive blanking tray in any unused bays to ensure proper airflow.
• You can mix SAS/SATA hard drives and SAS/SATA SSDs in the same server. However, you cannot configure a logical volume (virtual drive) that contains a mix of hard drives and SSDs. That is, when you create a logical volume, it must contain all SAS/SATA hard drives or all SAS/SATA SSDs.
4K Sector Format SAS/SATA Drives Considerations
• You must boot 4K sector format drives in UEFI mode, not legacy mode. UEFI mode is the system default.
Only if the mode has been changed and must be changed back to UEFI mode, see the following procedure.
• Do not configure 4K sector format and 512-byte sector format drives as part of the same RAID volume.
• For operating system support on 4K sector drives, see the interoperability matrix tool for your server:

Replacing a Front-Loading NVMe SSD
This section is for replacing 2.5-inch form-factor NVMe solid-state drives (SSDs) in front-panel drive bays.
Front-Loading NVMe SSD Population Guidelines
The server supports the following front drive bay configurations with 2.5 inch NVMe SSDs:
• Cisco UCS C220 M6 SAS/SATA (UCSC-C225-M6S)—Optional, front-loading drive bays 1 to 4 support
2.5-inch NVMe SSDs (with optional front NVMe cables).
• Cisco UCS C220 M6 NVMe (UCSC-C225-M6N)—10-drive backplane. Supports up to 10 2.5-inch
NVMe-only SSDs.
Figure 19: Drive Bay Numbering
Front-Loading NVME SSD Requirements and Restrictions
Observe these requirements:
• Hot-plug support must be enabled in the system BIOS. If you ordered the system with NVMe drives, hot-plug support is enabled at the factory.
• The NVMe-optimized, SFF 10-drive version, supports NVMe drives only.
Observe these restrictions:
• NVMe SFF 2.5-inch SSDs support booting only in UEFI mode. Legacy boot is not supported. For instructions on setting up UEFI boot, see
4K Sector Format SAS/SATA Drives Considerations, on page
• You cannot control NVMe PCIe SSDs with a SAS RAID controller because NVMe SSDs interface with the server via the PCIe bus.
• UEFI boot is supported in all supported operating systems. Hot-insertion and hot-removal are supported in all supported operating systems except VMWare ESXi.
Enabling Hot-Plug Support in the System BIOS
Hot-plug (OS-informed hot-insertion and hot-removal) is disabled in the system BIOS by default.
Cisco UCS C225 M6 Server Installation and Service Guide
45
Maintaining the Server
Enabling Hot-Plug Support Using the BIOS Setup Utility
• If the system was ordered with NVMe PCIe SSDs, the setting was enabled at the factory. No action is required.
• If you are adding NVMe PCIe SSDs after-factory, you must enable hot-plug support in the BIOS. See the following procedures.

Replacing Fan Modules
Tip Each fan module has a fault LED next to the fan connector on the motherboard. This LED lights green when the fan is correctly seated and is operating OK. The LED lights amber when the fan has a fault or is not correctly seated.
Caution You do not have to shut down or remove power from the server to replace fan modules because they are hotswappable. However, to maintain proper cooling, do not operate the server for more than one minute with any fan module removed.
Step 1
Step 2
Remove an existing fan module: a) Slide the server out the front of the rack far enough so that you can remove the top cover. You might have to detach cables from the rear panel to provide clearance.
Caution If you cannot safely view and access the component, remove the server from the rack.
b) Remove the top cover from the server as described in
Removing the Server Top Cover, on page 38 .
c) Grasp the fan module at its front and rear finger-grips. Lift straight up to disengage its connector from the motherboard.
Install a new fan module: a) Set the new fan module in place. The arrow printed on the top of the fan module should point toward the rear of the server.
b) Press down gently on the fan module to fully engage it with the connector on the motherboard.
c) Replace the top cover to the server.

Replacing CPUs and Heatsinks
Replacing CPUs and Heatsinks
This section contains CPU configuration rules and the procedure for replacing CPUs and heatsinks:
CPU Configuration Rules
This server has two CPU sockets on the motherboard. Each CPU supports eight DIM channels (16 DIMM slots). See
DIMM Slot Numbering, on page 58
.
• The server can operate with one CPU or two identical CPUs installed.
• The minimum configuration is that the server must have at least CPU 1 installed. Install CPU 1 first, and then CPU 2.
• The following restrictions apply when using a single-CPU configuration:
• Any unused CPU socket must have the protective dust cover from the factory in place.
• The maximum number of DIMMs is 16 (only CPU 1 channels A, B, C, D, E, F, G, and H).
Tools Required For CPU Replacement
You need the following tools and equipment for this procedure:
• T-20 Torx driver (for heatsink and CPU socket screws)
Cisco UCS C225 M6 Server Installation and Service Guide
49
Maintaining the Server
Replacing a CPU and Heatsink
• Heatsink cleaning kit—Supplied with replacement CPU. Orderable separately as Cisco PID
UCSX-HSCK=.
One cleaning kit can clean up to four CPUs.
• Thermal interface material (TIM)—Syringe supplied with replacement CPU. Use only if you are reusing your existing heatsink (new heatsinks have a pre-applied pad of TIM). Orderable separately as Cisco
PID UCS-CPU-TIM=.
One TIM kit covers one CPU.
See also
Additional CPU-Related Parts to Order with RMA Replacement CPUs, on page 57 .
Replacing a CPU and Heatsink
Caution CPUs and their sockets are fragile and must be handled with extreme care to avoid damaging pins. The CPUs must be installed with heatsinks and thermal interface material to ensure cooling. Failure to install a CPU correctly might result in damage to the server.
Step 1 Remove the existing CPU/heatsink assembly from the server: a) Shut down and remove power from the server as described in
Shutting Down and Removing Power From the Server, on page 37 .
b) Slide the server out the front of the rack far enough so that you can remove the top cover. You might have to detach cables from the rear panel to provide clearance.
Caution If you cannot safely view and access the component, remove the server from the rack.
c) Remove the top cover from the server as described in
Removing the Server Top Cover, on page 38 .
d) Use the T-20 Torx driver that is supplied with the replacement CPU to loosen the four captive nuts that secure the assembly to the motherboard standoffs.
Note Alternate loosening the heatsink nuts evenly so that the heatsink remains level as it is raised. Loosen the heatsink nuts in the order shown on the heatsink label: 4, 3, 2, 1, 6, 5.

Step 3 Apply new TIM to the heatsink:
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 5.
• 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.
a) Apply the cleaning solution that is included with the heatsink cleaning kit (UCSX-HSCK=) to the old TIM on the heatsink and let it soak for a least 15 seconds.
b) 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.
c) Using the syringe of TIM provided with the new CPU (UCS-CPU-TIM=), apply 4 cubic centimeters of thermal interface material to the top of the CPU. Use the pattern shown below to ensure even coverage.

Step 5
Step 6
Caution Use only the correct heatsink for your CPUs to ensure proper cooling.
Install the heatsink to the CPU: a) Align the heatsink over the CPU socket. Align the triangle-mark on the heatsink with the triangle-mark on the socket frame.
b) Use a T-20 Torx driver to tighten the six captive screws that secure the heatsink.
Caution Alternate tightening the heatsink screws evenly so that the heatsink remains level while it is lowered.
Tighten the heatsink screws in the order shown on the heatsink label (1, 2, 3, 4, 5, 6).
Reconnect any cables that you removed.
Power on the server.
Additional CPU-Related Parts to Order with RMA Replacement CPUs
When a return material authorization (RMA) of the CPU is done on a Cisco UCS C-Series server, additional parts might not be included with the CPU spare. The TAC engineer might need to add the additional parts to the RMA to help ensure a successful replacement.
Note The following items apply to CPU replacement scenarios. If you are replacing a system chassis and moving existing CPUs to the new motherboard, you do not have to separate the heatsink from the CPU.
Scenario 1—You are reusing the existing heatsinks or moving CPUs and heatsinks to a new node:
• Heatsink cleaning kit (UCSX-HSCK=)
One cleaning kit can clean up to four CPUs.
• Thermal interface material (TIM) kit (UCS-CPU-TIM=)
One TIM kit covers one CPU.
Scenario 2—You are replacing the existing heatsinks:
• Heatsink: UCSC-HSHP-225M6=
Cisco UCS C225 M6 Server Installation and Service Guide
57
Maintaining the Server
Replacing Memory DIMMs
New heatsinks have a pre-applied pad of TIM.
• Heatsink cleaning kit (UCSX-HSCK=)
One cleaning kit can clean up to four CPUs.
A CPU heatsink cleaning kit is good for up to four CPU and heatsink cleanings. The cleaning kit contains two bottles of solution, one to clean the CPU and heatsink of old TIM and the other to prepare the surface of the heatsink.
New heatsink spares come with a pre-applied pad of TIM. It is important to clean any old TIM off of the CPU surface prior to installing the heatsinks. Therefore, even when you are ordering new heatsinks, you must order the heatsink cleaning kit.
Replacing Memory DIMMs
Caution DIMMs and their sockets are fragile and must be handled with care to avoid damage during installation.
Caution Cisco does not support third-party DIMMs. Using non-Cisco DIMMs in the server might result in system problems or damage to the motherboard.
Note To ensure the best server performance, it is important that you are familiar with memory performance guidelines and population rules before you install or replace DIMMs.
DIMM Population Rules and Memory Performance Guidelines
This topic describes the rules and guidelines for maximum memory performance.
DIMM Slot Numbering
The following figure shows the numbering of the DIMM slots on the motherboard.

Figure 23: DIMM Slot Numbering
DIMM Population Rules and Memory Performance Guidelines
DIMM Population Rules
Observe the following guidelines when installing or replacing DIMMs for maximum performance:
• Each CPU supports eight memory channels, A through H.
• CPU 1 supports channels P1 A1, P1 A2, P1 B1, P1 B2, P1 C1, P1 C2, P1 D1, P1 D2, P1 E1, P1 E2,
P1 F1, P1 F2, P1 G1, P1 G2, P1 H1, and P1 H2.
• CPU 2 supports channels P2 A1, P2 A2, P2 B1, P2 B2, P2 C1, P2 C2, P2 D1, P2 D2, P2 E1, P2 E2,
P2 F1, P2 F2, P2 G1, P2 G2, P2 H1, and P2 H2.
• Each channel has two DIMM sockets (for example, channel A = slots A1, A2).
• When both CPUs are installed, populate the DIMM slots of each CPU identically.
• In a single-CPU configuration, populate the channels for CPU1 only (P1 A1 through P1 H2).
• 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 sections below list recommended configurations. Using 5, 7, 9, 10, or 11
DIMMs per CPU is not recommended.
Memory Population Order
Memory slots are color coded, blue and black. The color coded channel population order is blue slots first, then black.

You cannot mix DIMMs with different speeds and Revisions in the same bank (for example A1, B1). The Revision value depends on the manufactures. Two DIMMs with the same PID can have different
Revisions.
DIMM type
RDIMMs or LRDIMMs
You cannot mix DIMM types in a channel.
You cannot mix DIMM types in a bank.
Memory Mirroring
The CPUs in the server support memory mirroring only when an even number of channels are populated with
DIMMs. If one or three channels are populated with DIMMs, memory mirroring is automatically disabled.
Memory mirroring reduces the amount of memory available by 50 percent because only one of the two populated channels provides data. The second, duplicate channel provides redundancy.
Replacing DIMMs
Identifying a Faulty DIMM
Each DIMM socket has a corresponding DIMM fault LED, directly in front of the DIMM socket. See
for the locations of these LEDs. When the server is in standby power mode, these LEDs light amber to indicate a faulty DIMM.
Step 1
Step 2
Remove an existing DIMM: a) Shut down and remove power from the server as described in
Shutting Down and Removing Power From the Server, on page 37
.
b) Slide the server out the front of the rack far enough so that you can remove the top cover. You might have to detach cables from the rear panel to provide clearance.

Replacing Power Supplies
The server can have one or two Titanium 80PLUS rated power supplies. When two power supplies are installed they are redundant as 1+1 by default, but they also support cold redundancy mode. Cold redundancy (CR) suspends power delivery on one or more power supplies and forces the remainder of the load to be supplied by the active PSU(s). As a result, total power efficiency is improved by best utilizing the PSU efficiency when compared to load characteristics.

Storage Controller Card Firmware Compatibility
Firmware on the storage controller (RAID or HBA) must be verified for compatibility with the current Cisco
IMC and BIOS versions that are installed on the server. If not compatible, upgrade or downgrade the storage controller firmware using the Host Upgrade Utility (HUU) for your firmware release to bring it to a compatible level.
Note For servers running in standalone mode only: After you replace controller hardware (UCSC-RAID-M6,
UCSC-RAID-M6HD, UCSC-SAS-M6, or UCSC-SAS-M6HD), you must run the Cisco UCS Host Upgrade
Utility (HUU) to update the controller firmware, even if the firmware Current Version is the same as the
Update Version. This is necessary to program the controller's suboem-id to the correct value for the server
SKU. If you do not do this, drive enumeration might not display correctly in the software. This issue does not affect servers controlled in UCSM mode.

NVIDIA GRID License Server Overview
NVIDIA GRID License Server Overview
The NVIDIA M-Series GPUs combine Tesla and GRID functionality when the licensed GRID features such as GRID vGPU and GRID Virtual Workstation are enabled. These features are enabled during OS boot by borrowing a software license that is served over the network from the NVIDIA GRID License Server virtual appliance. The license is returned to the license server when the OS shuts down.
You obtain the licenses that are served by the GRID License Server from NVIDIA’s Licensing Portal as downloadable license files, which you install into the GRID License Server via its management interface.
Figure 39: NVIDIA GRID Licensing Architecture
There are three editions of GRID licenses, which enable three different classes of GRID features. The GRID software automatically selects the license edition based on the features that you are using.

Using gpumodeswitch
The command line utility gpumodeswitch can be run in the following environments:
• Windows 64-bit command prompt (requires administrator permissions)
• Linux 32/64-bit shell (including Citrix XenServer dom0) (requires root permissions)
Note Consult NVIDIA product release notes for the latest information on compatibility with compute and graphic modes.
The gpumodeswitch utility supports the following commands:
•
--listgpumodes
Writes information to a log file named listgpumodes.txt
in the current working directory.
•
--gpumode graphics
Switches to graphics mode. Switches mode of all supported GPUs in the server unless you specify otherwise when prompted.
•
--gpumode compute
Switches to compute mode. Switches mode of all supported GPUs in the server unless you specify otherwise when prompted.
Note After you switch GPU mode, reboot the server to ensure that the modified resources of the GPU are correctly accounted for by any OS or hypervisor running on the server.
