Processor Subsystem Chassis
CAUTION:
This unit weighs more than 55 kg (121.2 pounds). Material handling systems such as levers, slings,
or lifts are required to safely move it. When this is not possible, specially trained persons or
services (such as riggers or movers) must be used.
C06
Three people are required to handle this operation: one person to push the chassis, and two people to pull
the chassis.
Removal
Attention:
All components must be replaced to the location from which they were removed. Before
replacing processor subsystem chassis (backplane), check with your support center to ensure you have
been directed to replace the processor subsystem chassis (backplane) by a valid error code in Chapter 5,
“Error Code to FRU Index”, on page 345.
Attention:
This process requires:
v
A safe area reserved to store parts that are removed from the system during this procedure.
v
The use of a lift tool (part number 09P2481) and lift-plate assembly tool (part number 11P4369).
v
The following components must be removed from the processor subsystem chassis to reduce its weight
to the minimum.
– DCA Books
– Capacitor Books
– I/O Books
– Memory Books
– Processor Fan Assemblies
– MCM(s) (remove the MCMs only if the chassis is to be replaced)
– L3 Cache (remove the L3 cache only if the chassis is to be replaced)
– System Clock Card
v
The lift tool wheels must be chocked to prevent it from moving during the operation. The frame must not
be on its casters, and the leveling pads must be engaged to prevent the frame from moving during the
operation.
1. Read all safety instructions before performing this operation. Unpack the lift tool and follow assembly
instructions included with the tool. Inspect the tool for damage. Do not perform the removal procedure
with a damaged lift tool. Replace the blue lift plate with the orange lift plate (part number 11P4369).
Orient the two round holes in the lift plate to the side of the lift tool that will be closest to the frame.
2. Turn off power as described in “Powering Off and Powering On the System” on page 779.
3. Open the rack doors and remove them from the rack.
4. Verify that all cables are labeled. If not, label all cables and components along with their location at
the front and rear of the system.
5. Unplug all power cables from the line power source.
Attention:
Because this procedure is performed with power removed from the system, references
to using the white or green service buttons on the UEPO switch do not apply during the remainder of
this procedure.
6. Unplug any cables attached to the I/O books and processor subsystem DCAs.
7. At the back of the system, remove the safety bars from the I/O books and blanks, using an allen
wrench on the captive screws.
8. Remove the I/O books (and blanks if applicable). See “I/O Books and I/O Blanks” on page 792.
9. Remove the DCAs and capacitor books (and blanks if applicable). See “Processor Subsystem DCA
(Distributed Converter Assembly) Books and DCA Blanks” on page 797.
10. At the front of the system, remove the safety bars from the memory books and blanks.
