5. If you are installing a microprocessor in the blade server and a MPE unit or
expansion unit is attached to the blade server, remove the device (see
"Removing an expansion unit" on page 21).
6. Locate microprocessor socket 1; if a microprocessor is already installed, locate
microprocessor socket 2 (see "Blade server connectors" on page 14).
7. If you are installing a microprocessor in microprocessor socket 2, remove the
bezel assembly (see "Removing the bezel assembly" on page 22 for
instructions).
8. Loosen the four captive screws that secure the heat-sink filler and then remove
the filler from the microprocessor socket.
9. Use your fingers to remove the dust cover from the microprocessor socket.
10. Use your fingers to remove the protective cover from the microprocessor
retainer.
11. Install the microprocessor:
Attention:
v Do not use any tools or sharp objects to lift the locking lever on the
microprocessor socket. Doing so might result in permanent damage to the
system board.
v Hold the edges of the microprocessor. Do not touch the contacts on the
microprocessor or the contacts on the microprocessor socket. Touching
these contacts might result in permanent damage.
v Do not press the microprocessor into the socket.
v Make sure that the microprocessor is oriented and aligned correctly in the
socket before you try to close the microprocessor retainer.
a. Rotate the locking lever on the microprocessor socket from its closed and
locked position until it stops in the fully open position (approximately a 135°
angle), as shown.
b. Rotate the microprocessor retainer on the microprocessor socket from its
closed position until it stops in the fully open position (approximately a 135°
angle), as shown.
c. Touch the static-protective package that contains the new microprocessor
to any unpainted metal surface on the blade server or any unpainted metal
surface on any other grounded rack component in the rack that you are
installing the microprocessor in for at least 2 seconds; then, remove the
microprocessor from the package.
d. Remove the cover from the bottom of the microprocessor.
