Configuration
System Configuration
The system file (##A=sys.ini – where ## is the system unit ID number) resides on the
main system CPU, and contains information that is critical for proper operation. On
systems with a redundant CPU, it may be necessary to modify the system file on both of
the NSS CPUs individually, in order to maintain proper operation. DO NOT modify this
file unless instructed to do so by qualified technical support personnel.
MPU955 Admin Console uses the System Configuration utility to allow an administrator
to work with this file. When instructed, follow the steps below for viewing, modifying,
backing up, and restoring the ##A=sys.ini file.
For the purposes of this document, the system unit ID will be 01, so the system file name
will be 01A=sys.ini.
System Transfer
When performing a file transfer in the System Configuration utility, the system file is
written to the MPU955 Admin Console computer's hard drive as "01A=sys.ini" and
"01B=sys.ini" - depending on which CPU this function was performed. In most cases,
the system file residing on the MPU955 Admin Console computer's hard drive will be an
exact duplicate of the file being used on the system's CPU(s).
It is possible for the file on the local drive to differ from the one being used by the system,
when using the restore function. An administrator must be very careful when using the
backup and restore functions, as well as when retrieving and replacing the system file on
the CPU(s). It is very important that the administrator be aware of which CPU is being
updated.
