Step 1. Remove the cover (see
Step 2. Locate the fabric connector (see
Step 3. Orient the fabric connector on the system board.
Step 4. Using a #1 Phillips screwdriver, tighten the four captive screws to secure the fabric connector.
Attention: Make sure that the fabric connector is secure, but do not overtighten the screws, to
avoid damaging the connector.
After you install the fabric connector, complete the following steps:
1. Install the cover onto the compute node (see
instructions).
2. Install the compute node into the chassis (see
instructions).

Removing a microprocessor and heat sink

Use this information to remove a microprocessor and heat sink.
Note: This procedure should be performed only by trained service technicians.
Before you remove the microprocessor and heat sink, complete the following steps:
1. Read "Safety" on page iii
2. If the compute node is installed in a Flex System chassis, remove it (see
from a chassis" on page 880
3. Carefully lay the compute node on a flat, static-protective surface, orienting the compute node with the
bezel pointing toward you.
The following notes describe information that you must consider when you remove a microprocessor:
• A socket cover and heat-sink filler or a microprocessor and heat sink must always be installed on
microprocessor sockets 1, 3, and 4. Microprocessor socket 2 will only have a socket cover when a
microprocessor is not installed. If the compute node has only one microprocessor, it must be installed in
microprocessor socket 1.
• The microprocessor installation tool might become worn after several uses. Make sure that the tool can
hold the microprocessor securely if you are reusing an existing microprocessor installation tool. Do not
return the tool with other parts that you are returning.
