Figure 40 shows the location of the 33-MHz PCI expansion slots on the system
board.
Adapter considerations
Before you install adapters, review the following guidelines:
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
are included with the adapter.
v
Refer to the Network Attached Storage 200 User’s Reference for information
about configuring the adapter after it is installed.
v
You can install full-length adapters in all expansion slots.
v
You can install a 32-bit adapter in any of the PCI slots, but you might want to
install it in a 32-bit slot and use the 64-bit slots for 64-bit adapters.
v
Your appliance 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.
v
PCI slots 1 and 2 are on PCI bus A and PCI slots 3, 4, and 5 are on PCI bus B.
Note: PCI bus A is often referred to as bus 0; PCI bus B is often referred to as
bus 1.
The system scans PCI slots 1 through 5 to assign system resources; then the
system starts (boots) the PCI devices in the following order, if you have not
changed the default boot precedence: PCI slots 1 and 2, system board SCSI
devices, and then PCI slots 3 through 5.
