Use this information to remove the SAN Volume Controller 2145-CF8 microprocessor
and heat sink.
DANGER
Multiple
power cords. The product might be equipped with multiple power cords.
To remove all hazardous voltages, disconnect all power
cords.
To correctly perform this task, you must have
alcohol wipes and thermal grease available. If you do not already
have them, order these separately.
This service action requires you to remove
the cover and:
- Turn the node off.
- Disconnect the power cables.
- Disconnect the data cables.
Attention: - Do not permit the thermal grease on the microprocessor and heat
sink to come in contact with anything. Contact with any surface can
compromise the thermal grease and the microprocessor socket.
- Use great care when handling microprocessors. Dropping the microprocessor
during installation or removal can damage the contacts.
- Do not touch the microprocessor contacts; handle the microprocessor
by the edges only. Contaminants on the microprocessor contacts, such
as oil from your skin, can cause connection failures between the contacts
and the socket.
To remove a microprocessor and heat sink,
complete the following steps:
- Read the safety information to which Preparing to remove and replace parts refers.
- Follow the procedure in MAP 5350: Powering off a SAN Volume Controller node to
verify that the node data is mirrored and synchronized, and that there
are no dependent virtual disks (VDisks) before turning off the node.
- Slide
the node out on its slide rails to the fully extended position.
You can perform most service actions when the
node is fully extended from the rack on its slide rails. You can
leave the fibre-channel and Ethernet cables connected, if you are
using the cable-management arm and if you are not removing the node
from the rack. If the location of the node in the rack is too high
or too low to work comfortably, you can remove the node from the rack.
- When the node is completely turned off, remove the
cable-retention brackets and disconnect the power cables, as described
in Removing the cable-retention bracket.
- To make sure that you can replace all cables in the
same ports from which they were removed, label the port position of
each fibre-channel and Ethernet cable; then remove all cables from
the back of the node.
- Optional: Remove the node from the rack
and place it on a flat, static-protective surface. See Removing the SAN Volume Controller from a rack.
- Remove the top cover. See Removing the top cover.
- Disconnect any cables that impede access to the heat sink
( 3 in Figure 1) and
the microprocessor ( 1 ).

- 4 Lock tab
- 5 Retainer bracket
- Push the heat-sink release lever ( 1 )
down and away from the processor, then lift the lever until it is
perpendicular to the system board.
- Lift the heat sink from the side nearest the
lever, in its upright position and remove. After removal, place the
heat sink on its side on a clean, flat surface.
- Release the microprocessor-release lever ( 2 in Figure 2), by
pressing down on the curved end of the lever, moving that end away
from the middle of the processor, and releasing the lever up to the
open position.

- 2 Microprocessor-release lever
- 3 Microprocessor-bracket frame
- Open the microprocessor-bracket frame by lifting the tab
that is on the top edge. Keep the bracket frame in the open position,
as shown in Figure 2.
- Carefully lift the microprocessor straight up and out of
the socket, and place it on a static-protective surface. Be careful
to touch only the edges of the microprocessor.
- If you are instructed to return the microprocessor, follow
all packaging instructions, and use any packaging materials for shipping
that are supplied to you.
