DC 900-1333P 103
Device Type The
device_type parameter for both ICPs in the example file is ICP2432.
This indicates that the device type is an intelligent communications processor that
can be downloaded with software. All ICP devices installed in a Freeway
1100/1150/1200/1300 server must be of type
ICP2424, ICP2432, or ICP_IP, while
those installed in a Freeway 2000/4000/8800 server must be of type
ICP6000 or
ICP_IP. To avoid confusion with the configuration parameters for physical ICP
boards, configuration parameters specific to ICP_IP virtual devices are described
separately in Section 3.2.1.
Slave Address On a Freeway 1100, the
slave_address parameter for an ICP2424 (ISA-
bus board) identifies the dip switch setting (in hex) on the ICP (for example, 4 or
5). Refer to the ICP2424 Hardware Description and Theory of Operation manual
for information on how to configure ICPs on the ISAbus.
On a Freeway 1100/1150/1200/1300, the
slave_address parameter for an ICP2432
(PCI board), along with the
bus_number parameter, identifies the physical slot in
which the board resides. See the
freeway/boot/bootcfg.pci file for the slot-to-slave
address/bus number mapping.
On a Freeway 2000/4000/8800, the
slave_address parameter identifies the slave
address that was configured for the specific ICP on the VME bus. Refer to the
Freeway ICP6000R/ICP6000X Hardware Description manual for information on
how to configure ICPs on the VMEbus. Note that the slave address depends on
the type of CPU used in your Freeway. Appropriate slave addresses for each con-
figuration are indicated in the
freeway/boot/bootcfg.vme file.
Bus Number On a Freeway 1100/1150/1200/1300, the
bus_number parameter for an
ICP2432 (PCI board), along with the
slave_address parameter, identifies the phys-
ical slot in which the board resides. See the
freeway/boot/bootcfg.pci file for the slot-
to-slave address/bus number mapping. The
bus_number parameter is only used for
ICP2432 boards.
