c) Set the heatsink with CPU assembly down onto the CPU socket.
d) Use the T-30 Torx driver that is supplied with the replacement CPU to tighten the four captive nuts that
secure the heatsink to the motherboard standoffs.
Alternate tightening the heatsink nuts evenly so that the heatsink remains level while it is
installed. Tighten the heatsink nuts in the order shown on the heatsink label: 1, 2, 3, 4. The
captive nuts must be fully tightened so that the leaf springs on the CPU socket lie flat.
Caution
e) Replace the top cover to the server.
f) Replace the server in the chassis.
g) Wait for Cisco UCS Manager to complete its discovery of the server before powering it on.
Additional CPU-Related Parts to Order with CPU RMA
When a return material authorization (RMA) of the CPU occurs for a Cisco UCS B-Series server, additional
parts might not be included with the CPU spare bill of materials (BOM). The TAC engineer might need to
add the additional parts to the RMA to help ensure a successful replacement.
•
Scenario 1
—
You are reusing the existing heatsinks:
◦
Heat sink cleaning kit (UCSX-HSCK=)
◦
Thermal interface material (TIM) kit for M5 servers (UCS-CPU-TIM=)
•
Scenario 2
—
You are replacing the existing heatsinks:
◦
Heatsink for CPU 1: UCSC-HS-M5-F=
◦
Heatsink for CPU 2: UCSC-HS-M5-R=
◦
Heatsink cleaning kit (UCSX-HSCK=)
•
Scenario 3
—
You have a damaged CPU carrier:
◦
CPU Carrier: UCS-M5-CPU-CAR=
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.
Supported DIMMs
The DIMMs that this blade server supports are updated frequently. A list of supported and available DIMMs
is in Cisco UCS B200 M5 Specification Sheet.
Do not use any DIMMs other than those listed in the specification sheet. Doing so may irreparably damage
the server and result in down time.
