Refer to the operating system documentation to
determine if it supports hot-plug PCI adapters and, if
so, what the Attention LEDs indicate.
The following table describes the LEDs:
Adapter considerations:
Before you continue with the adapter-installation
procedure:
Ÿ
Review the documentation that comes with the
adapter and follow those instructions in addition to
these instructions. If you need to change the switch
or jumper settings on the adapter, follow the
instructions that come with the adapter
documentation.
Ÿ
You can install a full-length ISA adapter in the ISA
expansion slot.
Ÿ
You can install full-length adapters in PCI expansion
slots 1-4.
Ÿ
You can install only a short adapter in PCI expansion
slot 5.
Ÿ
You can install hot-plug PCI adapters in PCI slots
1–4, if the operating system supports this feature.
Non-hot-plug PCI adapters can also be installed in
these slots.
Ÿ
The server supports 5.0 V and universal PCI
adapters; it does not support 3.3 V adapters.
Note
A universal PCI adapter supports both 3.3 V and
5.0 V operation.
Ÿ
The server uses a rotational interrupt technique to
configure PCI adapters. Because of this technique,
you can install a variety of PCI adapters that currently
do not support sharing of PCI interrupts.
Ÿ
PCI slot 5 is on PCI bus 0 and PCI slots 1–4 are on
the PCI bus 1. Both PCI buses are primary buses.
