Required Equipment

The following equipment is used to perform the procedures in this chapter:

• Number 2 Phillips-head screwdriver
• Electrostatic discharge (ESD) strap or other grounding equipment such as a grounded mat

Shutting Down and Powering Off the Cisco CSP 2100 X2

Cisco CSP 2100 X2 can run in two power modes:

• Main power mode—Power is supplied to all Cisco CSP 2100 X2 components and any operating system on your drives can run.
• Standby power mode—Power is supplied only to the service processor and the cooling fans and it is safe to power off the Cisco CSP 2100 X2 from this mode.

You can invoke a graceful shutdown or a hard shutdown by using either of the following methods:

• Use the Cisco IMC management interface.
• Use the Power button on the Cisco CSP 2100 X2 front panel. To use the Power button, follow these steps:

Step 1 Check the color of the Power Status LED (see the “Front Panel LEDs” section).

• Green—Cisco CSP 2100 X2 is in main power mode and must be shut down before it can be safely powered off. Go to Step 2.
• Amber—Cisco CSP 2100 X2 is already in standby mode and can be safely powered off. Go to Step 3.

Step 2 Invoke either a graceful shutdown or a hard shutdown:

• Graceful shutdown—Press and release the Power button. The operating system performs a graceful shutdown and the Cisco CSP 2100 X2 goes to standby mode, which is indicated by an amber Power Status LED.
• Emergency shutdown—Press and hold the Power button for 4 seconds to force the main power off and immediately enter standby mode.

Step 3 Disconnect the power cords from the power supplies in your Cisco CSP 2100 X2 to completely power off the Cisco CSP 2100 X2.

Removing and Replacing the Cisco CSP 2100 X2 Top Cover

Step 1 Remove the top cover (see Figure 8-4).

a. If the cover latch is locked, use a screwdriver to turn the lock 90-degrees counterclockwise to unlock it. See Figure 8-4.

b. Lift on the end of the latch that has the green finger grip. The cover is pushed back to the open position as you lift the latch.

c. Lift the top cover straight up from the Cisco CSP 2100 X2 and set it aside.

Step 2 Replace the top cover:

Note The latch must be in the fully open position when you set the cover back in place, which allows the opening in the latch to sit over a peg that is on the fan tray.

a. With the latch in the fully open position, place the cover on top of the Cisco CSP 2100 X2 about one-half inch (1.27 cm) behind the lip of the front cover panel. The opening in the latch should fit over the peg that sticks up from the fan tray.

b. Press the cover latch down to the closed position. The cover is pushed forward to the closed position as you push down the latch.

c. If desired, lock the latch by using a screwdriver to turn the lock 90-degrees clockwise.

Figure 8-5 Replaceable Component Locations

Replacing SAS/SATA Hard Drives or Solid State Drives

This section includes the following information:

• SAS/SATA Drive Population Guidelines
• Replacing SAS/SATA Drives

SAS/SATA Drive Population Guidelines

Cisco CSP 2100 X2 supports the small form-factor (SFF) drives with 24-drive backplane and expander.
Cisco CSP 2100 X2 holds up to 24 2.5-inch SAS/SATA hard drives or solid state drives (SSDs). SAS/SATA drives are hot-swappable.

Note You cannot change the backplane type after-factory. To change a front panel/backplane configuration, a chassis replacement is required.

The drive-bay numbering is shown in Figure 8-6.

Figure 8-6 Drive Numbering, SFF Drives, 24-Drive Version

Observe these drive population guidelines for optimal performance:

• When populating drives, add drives in the lowest numbered bays first.
• Keep an empty drive blanking tray in any unused bays to ensure optimal airflow and cooling.
• You can mix hard drives and solid state drives in the same Cisco CSP 2100 X2. 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 hard drives or all SSDs.

4K Sector Format Drives Considerations

• You must boot 4K sector format drives in UEFI mode, not legacy mode. See Setting Up Booting in UEFI Mode in the BIOS Setup Utility or Setting Up Booting in UEFI Mode in the Cisco IMC GUI.
• Do not configure 4K sector format and 512-byte sector format drives as part of the same RAID volume.
• Operating system support on 4K sector drives is as follows: Windows: Win2012 and Win2012R2; Linux: RHEL 6.5, 6.6, 6.7, 7.0, 7.2; SLES 11 SP3, and SLES 12. ESXi/Vmware is not supported.

Replacing DIMMs

This section includes the following topics:

• Memory Performance Guidelines and Population Rules
• DIMM Replacement Procedure

Note To ensure the best performance, it is important that you are familiar with memory performance guidelines and population rules before you install or replace the memory.

Memory Performance Guidelines and Population Rules

This section describes the type of memory that Cisco CSP 2100 X2 requires and its effect on performance. The section includes the following topics:

• DIMM Socket Numbering
• DIMM Population Rules
• Memory Mirroring and RAS
• Lockstep Channel Mode

DIMM Socket Numbering

Figure 8-10 shows the numbering of the DIMM sockets and CPUs.

Figure 8-10 CPUs and DIMM Socket Numbering on Motherboard

DIMM Population Rules

Observe the following guidelines when installing or replacing DIMMs:

• Each CPU supports four memory channels.

– CPU1 supports channels A, B, C, and D.

– CPU2 supports channels E, F, G, and H.

• Each channel has three DIMM sockets (for example, channel A = slots A1, A2, and A3).

– A channel can operate with one, two, or three DIMMs installed.

– If a channel has only one DIMM, populate slot 1 first (the blue slot).

• When both CPUs are installed, populate the DIMM sockets of each CPU identically.

– Fill blue #1 slots in the channels first: A1, E1, B1, F1, C1, G1, D1, H1

– Fill black #2 slots in the channels second: A2, E2, B2, F2, C2, G2, D2, H2

– Fill white #3 slots in the channels third: A3, E3, B3, F3, C3, G3, D3, H3

• Any DIMM installed in a DIMM socket for which the CPU is absent is not recognized. In a single-CPU configuration, populate the channels for CPU1 only (A, B, C, D).
• Memory mirroring reduces the amount of memory available by 50 percent because only one of the two populated channels provides data. When memory mirroring is enabled, you must install DIMMs in sets of 4, 6, 8, or 12 as described in Memory Mirroring and RAS.
• The Tesla P100 GPU can support more than 1 TB of memory in Cisco CSP 2100 X2. All other NVIDIA GPUs can support only 1 TB or less of memory in Cisco CSP 2100 X2. Therefore, do not install more than fourteen 64-GB DIMMs when using an NVIDIA GPU card (other than Tesla P100) in Cisco CSP 2100 X2.
• Observe the DIMM mixing rules shown in Table 8-5 .

Memory Mirroring and RAS

The Intel E5-2600 CPUs within the Cisco CSP 2100 X2 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. Furthermore, if memory mirroring is used, DRAM size is reduced by 50 percent for reasons of reliability.

The memory mirroring configuration for Cisco CSP 2100 is similar to that of Cisco UCS C-Series servers. You can refer to Cisco UCS C-Series Rack Server specification sheet for details on populating recommended memory mirroring configurations:

• Cisco UCS C240 M4 High Density Rack Server (Small Form-Factor Disk Drive Model) Specification Sheet

Lockstep Channel Mode

When you enable lockstep channel mode, each memory access is a 128-bit data access that spans four channels.

Lockstep channel mode requires that all four memory channels on a CPU must be populated identically with regard to size and organization. DIMM socket populations within a channel (for example, A1, A2, A3) do not have to be identical but the same DIMM slot location across all four channels must be populated the same.

For example, DIMMs in sockets A1, B1, C1, and D1 must be identical. DIMMs in sockets A2, B2, C2, and D2 must be identical. However, the A1-B1-C1-D1 DIMMs do not have to be identical with the A2-B2-C2-D2 DIMMs.

DIMM Replacement Procedure

This section includes the following topics:

• Identifying a Faulty DIMM
• Replacing DIMMs

Identifying a Faulty DIMM

Each DIMM socket has a corresponding DIMM fault LED, directly in front of the DIMM socket. See Figure 8-3 for the locations of these LEDs. The LEDs light amber to indicate a faulty DIMM. To operate these LEDs from the SuperCap power source, remove AC power cords and then press the Unit Identification button.

Replacing DIMMs

Step 1 Power off the Cisco CSP 2100 X2 as described in Shutting Down and Powering Off the Cisco CSP 2100 X2.

Step 2 Slide the Cisco CSP 2100 X2 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.

Step 3 Remove the top cover as described in Removing and Replacing the Cisco CSP 2100 X2 Top Cover.

Step 4 Remove the air baffle that sits over the DIMM sockets and set it aside.

Step 5 Identify the faulty DIMM by observing the DIMM socket fault LEDs on the motherboard (see Figure 8-3).

Step 6 Remove the DIMMs that you are replacing. Open the ejector levers at both ends of the DIMM socket, and then lift the DIMM out of the socket.

Step 7 Install a new DIMM:

Note Before installing DIMMs, see the population guidelines. See Memory Performance Guidelines and Population Rules.

a. Align the new DIMM with the empty socket on the motherboard. Use the alignment key in the DIMM socket to correctly orient the DIMM.

b. Push down evenly on the top corners of the DIMM until it is fully seated and the ejector levers on both ends lock into place.

Step 8 Replace the air baffle.

Step 9 Replace the top cover.

Step 10 Replace the Cisco CSP 2100 X2 in the rack, replace cables, and then power on the Cisco CSP 2100 X2 by pressing the Power button.

Replacing CPUs and Heatsinks

This section contains the following topics:

• Special Information For Upgrades to Intel Xeon v4 CPUs
• CPU Configuration Rules
• Replacing a CPU and Heatsink
• Additional CPU-Related Parts to Order with RMA Replacement Motherboards

Special Information For Upgrades to Intel Xeon v4 CPUs

The minimum software and firmware versions required for the Cisco CSP 2100 X2 to support Intel v4 CPUs are as follows:

Note Cisco UCS Manager Release 2.2(4) introduced a server pack feature that allows Intel v4 CPUs to run with Cisco UCS Manager Release 2.2(4) or later.
The UCS Manager Capability Catalog must be updated to 2.2(7c) or later.
The server Cisco IMC/BIOS must be running the minimum version or later as described in Table 8-6.

Do one of the following actions:

• If your Cisco CSP 2100 X2’s firmware and/or Cisco UCS Manager software are already at the required levels shown in Table 8-6 , you can replace the CPU hardware by using the procedure in this section.
• If your Cisco CSP 2100 X2’s firmware and/or Cisco UCS Manager software is earlier than the required levels, use the instructions in the Cisco UCS C-Series Servers Upgrade Guide for Intel Xeon v4 CPUs to upgrade your software. After you upgrade the software, return to the procedure in this section as directed to replace the CPU hardware.

CPU Configuration Rules

Cisco CSP 2100 X2 has two CPU sockets. Each CPU supports four DIMM channels (12 DIMM sockets). See Figure 8-10.

• Cisco CSP 2100 X2 can operate with one CPU or with two identical CPUs installed.
• The minimum configuration is that Cisco CSP 2100 X2 must have at least CPU1 installed. Install CPU1 first, and then CPU2.
• The following restrictions apply when using a single-CPU configuration:

– The maximum number of DIMMs is 12 (only CPU1 channels A, B, C, and D).

– PCIe riser 2, which contains PCIe slots 4, 5, and 6 is unavailable.

– The PCIe SSD interposer board is unavailable.

Replacing a CPU and Heatsink

Note Cisco CSP 2100 X2 uses the new independent loading mechanism (ILM) CPU sockets, so no Pick-and-Place tools are required for CPU handling or installation. Always grasp the plastic frame on the CPU when handling.

Step 1 Power off the Cisco CSP 2100 X2 as described in Shutting Down and Powering Off the Cisco CSP 2100 X2.

Step 2 Slide the Cisco CSP 2100 X2 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.

Step 3 Remove the top cover as described in Removing and Replacing the Cisco CSP 2100 X2 Top Cover.

Step 4 Remove the plastic air baffle that sits over the CPUs.

Step 5 Remove the heatsink that you are replacing:

a. Use a Number 2 Phillips-head screwdriver to loosen the four captive screws that secure the heatsink.

Note Alternate loosening each screw evenly to avoid damaging the heatsink or CPU.

b. Lift the heatsink off of the CPU.

Step 6 Open the CPU retaining mechanism:

a. Unclip the first retaining latch labeled with the icon, and then unclip the second retaining latch labeled with the icon. See Figure 8-11.

b. Open the hinged CPU cover plate.

Figure 8-11 CPU Socket

Step 7 Remove any existing CPU:

a. With the latches and hinged CPU cover plate open, swing the CPU in its hinged seat up to the open position, as shown in Figure 8-11.

b. Grasp the CPU by the finger-grips on its plastic frame and lift it up and out of the hinged CPU seat.

c. Set the CPU aside on an antistatic surface.

Step 8 Install a new CPU:

a. Grasp the new CPU by the finger-grips on its plastic frame and align the tab on the frame that is labeled “ALIGN” with the hinged seat, as shown in Figure 8-12.

b. Insert the tab on the CPU frame into the seat until it stops and is held firmly.

The line below the word “ALIGN” should be level with the edge of the seat, as shown in Figure 8-12.

c. Swing the hinged seat with the CPU down until the CPU frame clicks in place and holds flat in the socket.

d. Close the hinged CPU cover plate.

e. Clip down the CPU retaining latch with the icon, and then clip down the CPU retaining latch with the icon. See Figure 8-11.

Figure 8-12 CPU and Socket Alignment Features

Step 9 Install a heat sink:

a. Apply the cleaning solution, which is included with the heatsink cleaning kit (UCSX-HSCK=, shipped with spare CPUs), to the old thermal grease on the heatsink and CPU and let it soak for a least 15 seconds.

b. Wipe all of the old thermal grease off the old heat sink and CPU using the soft cloth that is included with the heatsink cleaning kit. Be careful to not scratch the heat sink surface.

Note New heatsinks come with a pre-applied pad of thermal grease. If you are reusing a heatsink, you must apply thermal grease from a syringe (UCS-CPU-GREASE3=).

c. Align the four heatsink captive screws with the motherboard standoffs, and then use a Number 2 Phillips-head screwdriver to tighten the captive screws evenly.

Note Alternate tightening each screw evenly to avoid damaging the heatsink or CPU.

Step 10 Replace the air baffle.

Step 11 Replace the top cover.

Step 12 Replace the Cisco CSP 2100 X2 in the rack, replace cables, and then power on the Cisco CSP 2100 X2 by pressing the Power button.

Additional CPU-Related Parts to Order with RMA Replacement Motherboards

When a return material authorization (RMA) of the motherboard or CPU is done on a Cisco CSP 2100 X2, additional parts might not be included with the CPU or motherboard spare bill of materials (BOM). The TAC engineer might need to add the additional parts to the RMA to help ensure a successful replacement.

Note Cisco CSP 2100 X2 uses the new independent loading mechanism (ILM) CPU sockets, so no Pick-and-Place tools are required for CPU handling or installation. Always grasp the plastic frame on the CPU when handling.

• Scenario 1—You are reusing the existing heatsinks:

– Heat sink cleaning kit (UCSX-HSCK=)

– Thermal grease kit for C240 M4 (UCS-CPU-GREASE3=)

• Scenario 2—You are replacing the existing heatsinks:

– Heat sink (UCSC-HS-C240M4=)

– Heat sink cleaning kit (UCSX-HSCK=)

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 thermal interface material and the other to prepare the surface of the heatsink.

New heatsink spares come with a pre-applied pad of thermal grease. It is important to clean the old thermal grease off of the CPU prior to installing the heatsinks. Therefore, when you are ordering new heatsinks, you must order the heatsink cleaning kit.

Replacing a Cisco Modular RAID Controller Card

Cisco CSP 2100 X2 has an internal, dedicated PCIe slot on the motherboard for a Cisco modular RAID controller card (see Figure 8-13).

Figure 8-22 PCIe Riser Securing Features (Three-Slot Riser Shown)

Installing Multiple PCIe Cards and Resolving Limited Resources

When a large number of PCIe add-on cards are installed in the Cisco CSP 2100 X2, the system might run out of the following resources required for PCIe devices:

• Option ROM memory space
• 16-bit I/O space

The topics in this section provide guidelines for resolving the issues related to these limited resources:

• Resolving Insufficient Memory Space to Execute Option ROMs
• Resolving Insufficient 16-Bit I/O Space

Resolving Insufficient Memory Space to Execute Option ROMs

The system has very limited memory to execute PCIe legacy option ROMs, so when a large number of PCIe add-on cards are installed in the Cisco CSP 2100 X2, the system BIOS might not able to execute all of the option ROMs. The system BIOS loads and executes the option ROMs in the order that the PCIe cards are enumerated (slot 1, slot 2, slot 3, and so on).

If the system BIOS does not have sufficient memory space to load any PCIe option ROM, it skips loading that option ROM, reports a system event log (SEL) event to the Cisco IMC controller and reports the following error in the Error Manager page of the BIOS Setup utility:

To resolve this issue, disable the Option ROMs that are not needed for system booting. The BIOS Setup Utility provides the setup options to enable or disable the Option ROMs at the PCIe slot level for the PCIe expansion slots and at the port level for the onboard NICs. These options can be found in the BIOS Setup Utility Advanced > PCI Configuration page.

• Guidelines for RAID controller booting

If the Cisco CSP 2100 X2 is configured to boot primarily from RAID storage, make sure that the option ROMs for the slots where your RAID controllers installed are enabled in the BIOS, depending on your RAID controller configuration.

If the RAID controller does not appear in the system boot order even with the option ROMs for those slots are enabled, the RAID controller option ROM might not have sufficient memory space to execute. In that case, disable other option ROMs that are not needed for the system configuration to free up some memory space for the RAID controller option ROM.

• Guidelines for onboard NIC PXE booting

If the system is configured to primarily perform PXE boot from onboard NICs, make sure that the option ROMs for the onboard NICs to be booted from are enabled in the BIOS Setup Utility. Disable other option ROMs that are not needed to create sufficient memory space for the onboard NICs.

Resolving Insufficient 16-Bit I/O Space

The system has only 64 KB of legacy 16-bit I/O resources available. This 64 KB of I/O space is divided between the CPUs in the system because the PCIe controller is integrated into the CPUs. Cisco CSP 2100 X2 BIOS has the capability to dynamically detect the 16-bit I/O resource requirement for each CPU and then balance the 16-bit I/O resource allocation between the CPUs during the PCI bus enumeration phase of the BIOS POST.

When a large number of PCIe cards are installed in the system, the system BIOS might not have sufficient I/O space for some PCIe devices. If the system BIOS is not able to allocate the required I/O resources for any PCIe devices, the following symptoms have been observed:

• The system might get stuck in an infinite reset loop.
• The BIOS might appear to hang while initializing PCIe devices.
• The PCIe option ROMs might take excessive time to complete, which appears to lock up the system.
• PCIe boot devices might not be accessible from the BIOS.
• PCIe option ROMs might report initialization errors. These errors are seen before the BIOS passes control to the operating system.
• The keyboard might not work.

To work around this problem, rebalance the 16-bit I/O load using the following methods:

1. Physically remove any unused PCIe cards.

2. If the system has one or more Cisco virtual interface cards (VICs) installed, disable the PXE boot on the VICs that are not required for the system boot configuration by using the Network Adapters page in Cisco IMC Web UI to free up some 16-bit I/O resources. Each VIC uses a minimum 16 KB of 16-bit I/O resource, so disabling PXE boot on Cisco VICs would free up some 16-bit I/O resources that can be used for other PCIe cards that are installed in the system.

Installing a Trusted Platform Module (TPM)

The trusted platform module (TPM) is a small circuit board that connects to a motherboard socket and is secured by a one-way screw.

TPM 2.0 Considerations

Trusted platform module (TPM) version 2.0 is supported on Intel v3- or Intel v4-based platforms.

If there is an existing TPM 1.2 installed in the Cisco CSP 2100 X2, you cannot upgrade to TPM 2.0.

If there is no existing TPM in the Cisco CSP 2100 X2, you can install TPM 2.0. You must first upgrade to Intel v4 code, regardless of whether the installed CPU is Intel v3 or v4. TPM 2.0 requires Intel v4 code or later.

Note If the TPM 2.0 becomes unresponsive, reboot the Cisco CSP 2100 X2.

Installing the TPM Hardware

This section contains the following procedures, which must be followed in this order when installing and enabling a TPM:

1. Installing the TPM Hardware

2. Enabling TPM Support in the BIOS

3. Enabling the Intel TXT Feature in the BIOS

Note For security purposes, the TPM is installed with a one-way screw. It cannot be removed with a standard screwdriver.

Step 1 Prepare the Cisco CSP 2100 X2 for component installation:

Step 2 Power off the Cisco CSP 2100 X2 as described in Shutting Down and Powering Off the Cisco CSP 2100 X2.
