Matching Parameters
It is very important to understand that some parameters, such as the IRQ and
I/O Port, are set at both the hardware and AIX level, and the settings must be
identical.
Refer to the sections describing each ISA adapter configuration to know how to set
DIP switches on each particular adapter.
Shut down and power-off the system, and then physically install the adapter in an
ISA free slot.
6.3.6 Making ISA Adapters Available
After physically installing the adapter, boot the system again, and configure the ISA
adapter using smit isa fastpath.
If the ISA adapter is in the defined state, you can select Configure a Defined ISA
Adapter from the menu to set it to the Available state.
Otherwise, if the ISA adapter could not be set to the defined state since the SMIT
menu does not allow the adapter definition only, select Add an ISA Adapter to set
the parameter values, and configure it.
6.4 8-Port EIA-232 Asynchronous ISA Adapter (FC 2931)
This section provides information needed for installing and configuring the 8-Port
Asynchronous ISA Adapter. This adapter can be ordered as an optional feature on
PCI-based RS/6000 servers.
The 8-Port Asynchronous ISA Adapter is a multichannel, intelligent serial
communications feature which supports speeds of 155 Kbps for each asynchronous
port. It contains the following components:
8-port asynchronous card
8-port connector box
Optional media containing device driver or diagnostic software
The device driver for the 8-Port Asynchronous ISA Adapter is included in the
devices.isa.cxia fileset.
Note
Refer to the
8-Port Asynchronous ISA Adapter Installation Guide
shipped with
the adapter for detailed information on this adapter.
6.4.1 DIP-Switch Setting
The only parameter you have to set to install the adapter into the system is the
Bus
I/O Address
. Its possible values are set with four switches at the rear of the
adapter, and the possible switch settings are described in the following table.
