IBM Type 7977 manual Installing an adapter

Attention: Do not touch the thermal grease on the bottom of the heat sink after you remove the plastic cover. Touching the thermal grease will contaminate it.

9. Reinstall the microprocessor air duct on the fan cage.

If you have other devices to install or remove, do so now. Otherwise, go to “Completing the installation” on page 30.

Installing an adapter

The following notes describe the types of adapters that the server supports and other information that you must consider when you install an adapter:

vLocate the documentation that comes with the adapter and follow those instructions in addition to the instructions in this section. If you must change the switch or jumper settings on the adapter, follow the instructions that come with the adapter.

vAvoid touching the components and gold-edge connectors on the adapter.

vPCI slot 6 supports half-length 5.0 V PCI adapters only.

vPCI slot 1 supports half-length 3.3 V PCI adapters only.

vPCI slots 2 through 5 support full-length 3.3 V signaling adapters only.

vThe PCI configuration:

–Slot 1 is a PCI-Express x8 slot with x4 links, PCI Express 1.0a compliant.

–Slot 2 and 3 are PCI-Express x8 slots with x8 links, PCI Express 1.0a compliant. is the default slot for the optional ServeRAID-10is controller or the ServeRAID-8s controller.

–Slots 4 and 5 are PCI-X 133/64 slots, PCI-X 2.0 compliant.

–Slot 6 is a PCI 33/32 slot, PCI 2.2 compliant.

Note: The ServeRAID-8k, ServeRAID-8s, and the optional ServeRAID-10is SAS controllers override the standard functionality of the integrated SAS/SATA controller with RAID capabilities.

vThe system scans PCI slots 1 through 6 to assign system resources. The system then starts (boots) the system devices in the following order, if you have not changed the default boot precedence: integrated Ethernet controller, ServeRAID-8k SAS controller, and then PCI, PCI-X, and PCI-Express slots.

Note: To change the boot precedence for PCI and PCI-X devices, start the Configuration/Setup Utility program and select Start Options from the main menu. See the User’s Guide on the IBM System x Documentation CD for details about using the Configuration/Setup Utility program.

vThe server uses a rotational interrupt technique to configure PCI adapters so that you can install PCI adapters that do not support sharing of PCI interrupts.

vIn models with 12 hard disk drives, a ServeRAID-8s controller must be installed in PCI slot 2 and a ServeRAID-8k controller in the ServeRAID connector on the system board.

To install an adapter, complete the following steps:

1.Read the safety information that begins on page vii and “Installation guidelines” on page 7.

2.Turn off the server and peripheral devices, and disconnect the power cords and all external cables. Remove the left-side cover.
