Adapter considerations
Before you install adapters, review the following:
v
Locate the documentation that comes with the adapter and follow those
instructions in addition to the instructions given in this chapter. If you need to
change the switch or jumper settings on your adapter, follow the instructions
that come with the adapter.
v
You can install full-length adapters in all expansion slots.
v
You can install a 32-bit adapter or device in any of the PCI slots.
v
Your server supports 5.0 V signalling or universal PCI adapters in slots 1, 2, and
3; it supports 3.3 V signalling or universal PCI adapters in slots 4 and 5.
Note:
Some full-length adapters with attached daughterboards might interfere
with SCSI channel B if installed in slot 1. Install this type of adapter in
slot 2, 3, 4, or 5.
v
You might require additional power supplies if you add adapters that have
electrical current requirements that exceed the installed power-supply
capabilities.
v
Your server uses a rotational interrupt technique to configure PCI adapters.
Therefore, you can install a variety of PCI adapters that currently do not support
sharing of PCI interrupts.
v
The optional IBM Remote Supervisor Adapter must be installed in PCI slot 1
only. Use the ribbon cable that comes with the adapter to connect the adapter to
the system-management connector (J54) on the system board. The external
power adapter that comes with the adapter is not required with this server.
v
PCI slot 1 is on PCI bus A, PCI slots 2 and 3 are on PCI bus B, and PCI slots 4
and 5 are on PCI bus C.
Note:
PCI bus A is often referred to as bus 0; PCI bus B is often referred to as
bus 1; and PCI bus C is often referred to as bus 2.
