Installing An Additional Microprocessor - IBM 84885BU Maintenance And Troubleshooting Manual

10. Replace the cover (see "Replacing the side cover" on page 29).
11. Reconnect the external cables and power cords. Turn on the attached devices,
12. Use the SCSISelect program to configure SCSI channel B (see the User's

Installing an additional microprocessor

The following notes describe the type of microprocessor that the server supports
and other information that you must consider when installing a microprocessor:
v The server comes with one microprocessor and supports up to two
v Read the documentation that comes with the microprocessor to determine
v (Optional) Obtain an SMP-capable operating system. For a list of supported
v The microprocessors must have the same cache size and type, and the same
v Terminator cards are not required for empty microprocessor sockets. However,
v The microprocessor speeds are automatically set for this server; therefore, you
v The system board contains an integrated voltage regulator for microprocessor 1;
v These instructions assume that you are installing microprocessor 2.

4. Open the front adapter-support bracket and remove the rear adapter-retention
bracket from the PCI-X slots (see "Installing an adapter" on page 51 for
instructions). You might also have to remove longer adapters for access to the
SCSI connectors on the system board.
5. Connect the SCSI signal cable end labeled "PLANAR" to the connector for
SCSI channel B on the system board (see "System board internal connectors"
on page 86 for the location of the SCSI channel B connector).
6. Route the SCSI cable to the adapter slot that has the special SCSI-knockout
slot cover on the back of the server (see "Connecting the cables" on page 61
for an illustration of the SCSI-knockout slot cover, normally in PCI slot 3).
Make sure the cable does not block the flow of air to the hard disk drives.
Note: You can move the special SCSI-knockout slot cover to a different slot if
needed.
7. Remove the SCSI-connector knockout from the PCI-X slot cover; then, insert
the external SCSI connector on the SCSI cable into the knockout opening and
secure it with the attached screws.
8. Replace any adapters you removed in step 4. Close the front adapter-support
bracket and replace the rear adapter-retention bracket.
9. Replace the support bracket (see "Removing and installing the support
bracket" on page 32).

do not have to set any microprocessor frequency-selection jumpers or switches.
you must install a voltage regulator module (VRM) on the system board when
you install microprocessor 2. The VRM comes in the microprocessor option kit.
