Removing the Cartridge From the Chassis

NOTE: You do not have to power off the chassis, but you must decommission the cartridge before removing it from the chassis.

1. Decommission the cartridge by using Cisco UCS Manager.

UCS Manager CLI and GUI Configuration Guides

CAUTION: Do not remove the cartridge from the chassis if the cartridge is powered on in main power mode (the power LED is green). The cartridge power LED must be amber, indicating that the CPU subsystem is in standby. You must decommission the cartridge before you pull it from the chassis.

2. Check the color of the cartridge power status LED:

–Green—The CPU subsystem is in main power mode. Do not remove the cartridge.

–Amber—The CPU subsystem is in standby mode and the cartridge can be pulled from the chassis (only after decommission in UCS Manager).

–Off—The CPU subsystem power is off and the cartridge can be pulled from the chassis any time.

3. Remove a cartridge from the chassis:

a. Squeeze the cartridge locking mechanism and the release lever together (see Removing the Cartridge From the Chassis).

b. Slide the cartridge out of the chassis and set it on an antistatic surface.

4. Reinstall a cartridge to the chassis:

a. Carefully align the cartridge with the empty bay, keeping the cartridge level.

b. Slide the cartridge into the chassis until the locking mechanism clicks and locks the cartridge in place.

Replacing a CPU

■CPU Population Guidelines

■Replacing a CPU

CPU Population Guidelines

CAUTION: Use only Cisco-certified CPU replacement parts.

CAUTION: CPUs and their motherboard sockets are fragile and must be handled with care to avoid damaging pins during installation. You must use the Pick and Place tool as described in the following procedure to prevent damage to the contact pins between the socket and the CPU. Do not attempt this procedure without the required tool, which is included with each CPU option kit.

CAUTION: The CPUs must be installed with heatsinks and their thermal grease to ensure proper cooling. Failure to install a CPU correctly might result in damage to the server.

■The minimum configuration is one CPU installed in the CPU 1 socket (see Internal Component Locations).

■If the cartridge has two CPUs, they must be two identical CPUs. Do not mix CPU types or speeds.

Replacing a CPU

1. Decommission and power off the cartridge before you remove it from the chassis, as described in Removing the Cartridge From the Chassis.

2. Remove the cover from the cartridge, as described in Removing the Cartridge Cover.

3. Carefully lift the two air baffle-strips from the cartridge and set them aside. The holes in the strips fit over the heatsink screws.

4. Remove the heatsink:

CAUTION: To avoid damaging the CPU or heatsink, alternate loosening each screw evenly until the heatsink can be lifted from the standoffs.

a. Use a #2 Phillips-head screwdriver to loosen the four heatsink captive screws (see Removing the Heatsink and Opening the CPU Socket Mechanism).

b. Lift the heatsink straight up and set it aside.

5. Unclip the first CPU retaining lever that is labeled with the icon.

6. Unclip the second retaining lever that is labeled with the icon.

NOTE: Do not allow the lever to spring upward, which might dislodge the CPU.

7. Open the socket cover-plate and hinge it upward to provide clearance (see Removing the Heatsink and Opening the CPU Socket Mechanism).

9. 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 CPU and Socket Alignment Features.

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 CPU and Socket Alignment Features.

1. Swing the hinged seat with the CPU down until the CPU frame clicks in place and holds flat in the socket.
2. Close the hinged CPU cover plate.
3. Clip down the CPU retaining latch with the
icon, and then clip down the CPU retaining latch with the icon. See CPU Socket.

Figure 7 CPU and Socket Alignment Features

 

10. Install a heat sink:

CAUTION: The heat sink must have new thermal grease on the heatsink-to-CPU surface to ensure proper cooling. The thermal grease provided in the kit has very specific thermal properties; do not substitute thermal grease from other sources. Using other thermal grease might lead to system damage.

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=).

–If you are installing a new heatsink, peel the protective tape from the pre-applied pad of thermal grease on the underside of the new heatsink, then skip to step Set the heatsink in place, aligning its three captive screws with the three standoffs on the CPU socket.

–If you are re-using the heatsink that you removed earlier, continue with the following step:

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

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

c. Using the syringe of thermal grease (UCS-CPU-GREASE3=) provided with the CPU, apply 2 cubic centimeters of thermal grease to the top of the CPU. Use the pattern shown in Thermal Grease Application Pattern to ensure even coverage.

Figure 8 Thermal Grease Application Pattern

 

 

d. Set the heatsink in place, aligning its three captive screws with the three standoffs on the CPU socket.

CAUTION: To avoid damaging the CPU or heatsink, alternate tightening each screw evenly to keep the heatsink level.

e. Use a #2 Phillips-head screwdriver to tighten the three heatsink captive screws.

11. Install the two air baffle-strips to the cartridge. The holes in the strips fit over the heatsink screws.

12. Replace the cartridge cover.

13. Replace the cartridge to the chassis, then power it on and recommission using Cisco UCS Manager.

Replacing a Memory DIMM

■DIMM Population Guidelines

■Replacing a DIMM

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 memory.

DIMM Population Guidelines

Each CPU has four memory channels (for example, A, B, C, D) that have two DIMM slots each (see DIMM Slot Numbering). Observe the following guidelines when installing DIMMs:

■When installing DIMMs, load slot 1 of each channel first.

■In a two-CPU cartridge, distribute the DIMMs evenly. Load DIMMs in the following order for best performance:

1. A1, E1, B1, F1, C1, G1, D1, H1

2. A2, E2, B2, F2, C2, G2, D2, H2

■In a single-CPU cartridge (CPU 1 only), distribute the DIMMs evenly. Load DIMMs in the following order for best performance:

1. A1, B1, C1, D1

2. A2, B2, C2, D2

■Do not mix DIMM types in the same cartridge (for example, RDIMM and LRDIMM).

■Only RDIMMs are supported. The supported RDIMMs are: 16 GB, DDR, 2133 MHz, RDIMM/PC3-17000/dual rank/x4/1.2v

■Only ECC DIMMs are supported.

Figure 9 DIMM Slot Numbering

 

 

Replacing a DIMM

1. Decommission and power off the cartridge before you remove it from the chassis, as described in Removing the Cartridge From the Chassis.

2. Remove the cover from the cartridge, as described in Removing the Cartridge Cover.

3. Open the ejector levers at both ends of the DIMM slot, and then lift the DIMM out of the slot.

4. Install the new DIMM:

NOTE: Before installing DIMMs, see DIMM Population Guidelines.

a. Align the new DIMM with the empty slot on the motherboard. Use the alignment key in the DIMM slot 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.

5. Replace the cartridge cover.

6. Replace the cartridge to the chassis, then power it on and recommission using Cisco UCS Manager.

Replacing an RTC Battery

Each cartridge has a real-time clock (RTC) battery set in a vertical battery holder. The RTC battery retains cartridge settings when the server is disconnected from power.

The battery type is CR2032. Cisco supports the industry-standard CR2032 battery, which can be purchased from most electronic stores.

1. Decommission and power off the cartridge before you remove it from the chassis, as described in Removing the Cartridge From the Chassis.

2. Remove the cover from the cartridge, as described in Removing the Cartridge Cover.

3. The battery location is shown in Position of the RTC Battery. Gently pry the holding clip away from the top of the battery while you pull the battery up out of the vertical holder.

4. Insert the new battery to the holder.

NOTE: The positive, flat side of the battery with the + symbol should face toward the center of the cartridge.

5. Replace the cartridge cover.

6. Replace the cartridge to the chassis, then power it on and recommission using Cisco UCS Manager.

Installing a Trusted Platform Module

The trusted platform module (TPM) is a small circuit board that attaches to a motherboard socket. The TPM location is shown in Position of the RTC Battery.

NOTE: For security purposes, the TPM is installed with a one-way screw. Field replacement is not supported. If the cartridge is returned through RMA, you must order a TPM with the replacement cartridge.

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 Policy

3. Enabling TXT Support in the BIOS Policy

Installing the TPM Hardware

1. Decommission and power off the cartridge before you remove it from the chassis, as described in Removing the Cartridge From the Chassis.

2. Remove the cover from the cartridge, as described in Removing the Cartridge Cover.

3. Install a TPM:

a. Locate the TPM socket location on the motherboard, as shown in Position of the RTC Battery.

b. Align the connector that is on the bottom of the TPM circuit board with the motherboard TPM socket. Align the screw hole on the TPM board with the screw hole adjacent to the TPM socket.

c. Push down evenly on the TPM to seat it in the motherboard socket.

d. Install the single one-way screw that secures the TPM to the motherboard.

4. Replace the cartridge cover.

5. Replace the cartridge to the chassis, then power it on and recommission using Cisco UCS Manager.

6. Click the Trusted Platform sub-tab.

7. To enable TPM support, click Enable or Platform Default.

8. Click Save Changes.

9. Continue with Enabling TXT Support in the BIOS Policy.

Enabling TXT Support in the BIOS Policy

Intel Trusted Execution Technology (TXT) provides greater protection for information that is used and stored on the business server. A key aspect of that protection is the provision of an isolated execution environment and associated sections of memory where operations can be conducted on sensitive data, invisibly to the rest of the system. Intel TXT provides for a sealed portion of storage where sensitive data such as encryption keys can be kept, helping to shield them from being compromised during an attack by malicious code.

NOTE: TXT support is disabled by default in the Cisco UCS Manager 2.2(4) and later BIOS policy. To enable TXT support, use the following procedure.

1..In the Cisco UCS Manager Navigation pane, click the Servers tab.

2. On the Servers tab, expand Servers > Policies.

3. Expand the node for the organization where you want to configure TPM.

4. Expand BIOS Policies and select the BIOS policy for which you want to configure TPM.
