1. To help you work safely with Storwize V7000 Unified file module, read the
safety information in "Safety" on page xi, "Safety statements" on page xiii,
and "Installation guidelines" on page 58.
2. Turn off the server and peripheral devices, then label and disconnect both
power cords and all external cables
3. Remove the cover, as described in "Removing the cover" on page 87.
4. Depending on which microprocessor you are removing, remove the following
components, if needed:
v Microprocessor 1: PCI riser card assembly 1 and DIMM air baffle, as
described in "Removing a PCI riser-card assembly" on page 105 and
"Removing the DIMM air baffle" on page 98.
Note: If there are two microprocessors, you must remove PCI riser card
assembly 2 and microprocessor 2 air baffle first, as described in "Removing
a PCI riser-card assembly" on page 105 and "Removing the microprocessor
2 air baffle" on page 95.
v Microprocessor 2: PCI riser card assembly 2 and microprocessor 2 air baffle,
as described in "Removing a PCI riser-card assembly" on page 105 and
"Removing the microprocessor 2 air baffle" on page 95.
5. Open the heat-sink release lever to the fully open position. See Figure 39.
