UCS Manager CLI and GUI Configuration Guides

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 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

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.

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. 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 three heatsink captive screws (see Removing the Heatsink and Opening the CPU Socket Mechanism).

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

4. Carefully unhook the CPU socket locking lever and hinge it open to provide clearance (see Removing the Heatsink and Opening the CPU Socket Mechanism).

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

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

Figure 5 Removing the Heatsink and Opening the CPU Socket Mechanism

 

 

 

6. Remove the existing CPU from the socket using the Pick and Place tool that is provided with a CPU spare. This tool picks straight up on the CPU to avoid damaging the socket. See CPU Pick and Place Tool.

a. Press the release button on the tool to open its internal clasp hooks.

b. Place the tool onto the CPU socket. Orient the tool so that the arrow on the tool is aligned with the registration mark (small triangle) that is on the CPU socket.

c. Press the grasping lever to make the tool grasp the CPU.

d. Lift the tool with CPU straight up from the socket.

e. Press the release button on the tool to set the CPU on an antistatic surface.

10. Install a CPU heatsink:

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 avoid scratching 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 9 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 (see Closing the CPU Socket Mechanism and Installing the Heatsink).

11. Replace the cartridge cover.

12. 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

The CPU has two memory channels (A, B) that have two DIMM slots each. Observe the following guidelines when installing DIMMs:

■When installing DIMMs, load slot 2 (the blue slot) of each channel first. Load DIMMs in the following order for best performance: A2, B2, A1, B1.

■Only DDR3 UDIMMs are supported.

Supported UDIMM: 8GB, DDR3, 1600 MHz, ECC, UDIMM/PC3-12800/dual rank/x8/1.35v

■Only ECC DIMMs are supported.
