defective microprocessor is replaced or if the thermal material is contaminated
or has come in contact with another object other than its paired microprocessor.
3.
A heat-sink FRU can be ordered separately if the thermal material becomes
contaminated.
To remove a microprocessor, complete the following steps.
Microprocessor 1
and heat sink
Microprocessor 2
Heat sink
Microprocessor
heat sink filler
1.
Before you begin, read “Safety” on page v and “Installation guidelines” on
page 49.
2.
If the blade server is installed in a BladeCenter unit, remove it (see
“Removing the blade server from the BladeCenter unit” on page 52 for
instructions).
3.
Remove the blade server cover (see “Removing the blade server cover” on
page 55 for instructions).
4.
If an optional expansion unit is installed, remove the expansion unit (see
“Removing an optional expansion unit” on page 84).
5.
Locate the microprocessor that will be removed (see “Blade server connectors”
on page 15).
6.
Before removing the microprocessor, you must remove the memory module
closest to the microprocessor.
a.
If you are removing microprocessor 1, remove the memory module or
DIMM filler from DIMM connector 1 (see “Removing a memory module”
on page 64).
b.
If you are removing microprocessor 2, remove the memory module or
DIMM filler from DIMM connector 6 (see “Removing a memory module”
on page 64).
7.
Remove the heat sink.
Attention:
Do not touch the thermal material on the bottom of the heat sink.
Touching the thermal material will contaminate it. If the thermal material on
the microprocessor or heat sink becomes contaminated, you must replace the
heat sink.
a.
Loosen the screw on one side of the heat sink to break the seal with the
microprocessor.
b.
Use a screwdriver to loosen the screws on the heat sink, rotating each
screw two full turns until each screw is loose.
c.
Use your fingers to gently pull the heat sink from the microprocessor.
