IBM® xSeries 360: User’s Reference
The following lights are provided for monitoring adapter status:
• Power-on lights for hot-plug PCI-X slots
• Internal attention lights for hot-plug PCI-X slots
If the operating system supports hot-plug PCI/PCI-X adapters, you can replace a
failing hot-plug PCI/PCI-X adapter with a new adapter of the same type without
turning off power to the server. If the operating system and adapter also support the
hot-add feature, you can install a new adapter without turning off the power to the
server.
Attention: Do not remove a hot-plug PCI/PCI-X adapter before determining whether
the operating system requires you to disable the hot-plug PCI-X slot that contains the
adapter. Failing to disable the slot in this situation might cause the server to lock up.
Refer to the operating-system documentation.
Adapter considerations
Before you install adapters, review the following:
• Locate the documentation that comes with the adapter and follow those
instructions 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 PCI-X slot you will need
this documentation.
• If you install a ServeRAID adapter for use with the internal hot-swap hard disk
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
support 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 .
Installing a hot-plug PCI or PCI-X adapter
This section describes how to install a hot-plug PCI/PCI-X adapter. Before you
continue 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.
Notes:
1. Ensure that the PCI hot-plug device driver is installed. For details, see the
documentation that came with the adapter.
2. If you are installing a ServeRAID adapter, go to “Installing a ServeRAID adapter”
on page 70. If you are replacing the Remote Supervisor Adapter, go to
