Introduction
Overview
This guide consists of two main sections: NAC Maintenance and
Administration programs, and NAC error messages.
The NAC Maintenance and Administration program section is also
separated into three chapters. These chapters provide information on
shutting down the system, restarting the system, backing up the customer
database on tape, restoring the database, configuring the NAC hardware,
and changing the database configuration.
The NAC error messages section lists the operating and task errors that can
be generated during the NAC operation.
Background Diagnostics
Background diagnostic programs are run regularly on the NAC.
Bootable
SSID
The NAC operating system tape contains a bootable Standalone System
Interactive Diagnostics (SSID) kernel for the MVME167 processor. This
allows the installer to boot the SSID kernel when booting from the Release
2 operating system tape.
The following procedure is used to boot this system from tape:
1Boot the NAC.
2Press {Break}
at the prompt, Autoboot in Progress...To abort hit
[Break].

553-4011-510 Standard 1.0 November 1994
The following procedure is used to boot SSID from the hard disk:

For more information about SSID, refer to the Application Module
Advanced Maintenance Guide (533-3201-512).
NAC polls Meridian MAX
Whenever
the NAC is switched on, it polls the Meridian MAX systems
connected to it and requests acknowledgement. This poll is taken at a
predetermined rate, and constantly repeated while the NAC is operating.
The Meridian MAX system (V ersion 4.3x, Version 6.xx, and higher) is
programmed to seek and respond to the NAC poll.
Provided that the poll is taken by the NAC and responded to by the
Meridian MAX, the system can interact with the Meridian MAX system.
If the NAC does not receive an acknowledgement within a specified time
interval, the NAC reports that it cannot connect to the Meridian MAX
system.
Error logging and corrective action by NAC software
The NAC has full reporting capability if an error occurs in any task. These
errors are logged in the NAC error log file. When possible, corrective
action is taken by the NAC software.
Power-up diagnostics.
Hardware
diagnostics automatically execute at power -up. This prompts any
detected faults to be displayed on the NAC system console. These
diagnostics test the memory , I/O ports, and system console keyboard.
Hardware detection
The operating system installation procedure performs a hardware automatic
detection routine and displays the system’ s hardware on the screen. This
includes the CPU board, memory, hard disk, and tape drive. The installation
procedure can be aborted if the hardware configuration being displayed is
inaccurate.
