Installing A Hot-Plug Pci Or Pci-X Adapter - IBM xSeries 360 Type 8686 Installation Manual

•
To the right of PCI-X slot number 1 (as viewed from the front), there is a 33 MHz 64-bit
slot dedicated to the Remote Supervisor Adapter.
Before you install adapters, review the following:

Installing a hot-plug PCI or PCI-X adapter

This section describes how to install a hot-plug PCI/PCI-X adapter. Before you con-
tinue with the adapter-installation procedure, note that all six PCI-X slots support hot-
plug, 64-bit, PCI/PCI-X adapters. If PCI/PCI-X adapters are installed in both slots 1
and 2, they operate at 100 MHz or less, depending on the capacity of the adapter. If
one adapter is installed in slot 1 and slot 2 is empty, the adapter in slot 1 can operate
at 133 MHz.
Note: Ensure that the PCI hot-plug device driver is installed. For details, see the doc-
Complete the following steps to install a hot-plug PCI/PCI-X adapter:
1. Review the safety precautions beginning on page v and "Handling static-sensitive
Bus B (hot-plug)
— One 133 MHz 64-bit PCI-X adapter (slot 1)
— Two 100 MHz 64-bit PCI-X adapters (slots 1 and 2)
— Two 66 MHz 64-bit PCI-X adapters (slots 1 and 2)
— Two 66 MHz 64-bit PCI adapters (slots 1 and 2)
— Two 33 MHz 64-bit PCI adapters (slots 1 and 2)
Locate the documentation that comes with the adapter and follow those instruc-
tions in addition to the instructions in this chapter. If you need to change switch
settings or jumper settings on the adapter, follow the instructions that come with
the adapter.
Locate the documentation that comes with your operating system. If the operating
system provides a way to disable or enable a hot-plug PCI/PCI-X slot, you will
need this documentation.
If you install a ServeRAID
drives, you must connect the internal channel cable between the adapter and the
SCSI RAID cable connector (J43) on the system board. However, if you do this,
you cannot install a full-length, wide adapter in PCI-X slot 1.
The server supports only 3.3 V PCI or PCI-X adapters.
The server uses a rotational interrupt technique to configure PCI/PCI-X adapters.
You can use this technique to install PCI/PCI-X adapters that currently do not sup-
port sharing of PCI interrupts.
PCI-X slots 3 through 6 are on PCI bus A; PCI-X slots 1 and 2 are on PCI bus B.
By default, the server starts (boots) devices in the following order: system IDE and
SCSI devices, then PCI/PCI-X devices.
Note: To change the startup order, start the Configuration/Setup Utility program
and select Start Options from the main menu. Then, select the Startup
Sequence Options.
