6: Customizing the System Configuration
DC 900-1333Q 169
Device Type The
device_type parameter for both ICPs in the example file is ICP2432.
This indicates that the device type is a PCI-based intelligent communications pro-
cessor model ICP2432 or ICP2432B that can be downloaded with software. All
ICP devices installed in a Freeway 3xxx server must be of type
ICP2432 or ICP_IP. To
avoid confusion with the configuration parameters for physical ICP boards, con-
figuration parameters specific to ICP_IP virtual devices are described separately
in Section 6.3.2.
Slave Address The
slave_address parameter for an ICP2432B (PCI board), along with
the
bus_number parameter, identifies the physical slot in which the board resides.
Refer to the Hardware Installation Guide for your Freeway model for the slot-to-
slave address/bus number mapping. The
slave_address can be represented as a dec-
imal or hexadecimal number. When using hexadecimal, be sure to precede the
number with “0x”.
Bus Number The
bus_number parameter for an ICP2432B (PCI board), along with the
slave_address parameter, identifies the physical slot in which the board resides.
Refer to the Hardware Installation Guide for your Freeway model for the slot-to-
slave address/bus number mapping. The
bus_number can be represented as a deci-
mal or hexadecimal number. When using hexadecimal, be sure to precede the
number with “0x”.
Download Script The
download_script parameter define the name of a download script
file that can be used by the ICP download utility. A download script file is
included on each protocol installation CDROM. This file normally has a name
such as
ppploadb where ppp represents the protocol to be downloaded. If no path
name is provided, Freeway assumes the path is
/tmp/boot/. Use a fully qualified path
name to the download script file if the file is placed in another directory.
6.3.2 Configuration Parameters for ICP_IP Virtual Devices
ICP_IP virtual devices behave just like physical ICP boards except that they send and
receive data via an IP network rather than via a serial line. This section describes the
