1 INTRODUCTION

The software described in this manual is intended to be used in the ESO VLT project by ESO and authorized external contractors only.

While every precaution has been taken in the development of the software and in the preparation of this documentation, ESO assumes no responsibility for errors or omissions, or for damage resulting from the use of the software or of the information contained herein.

1.1 Purpose

This document is the Maintenance Manual of the FIERA CCD Controller Software.

It is intended to provide people who want to do software maintenance operations to a FIERA CCD controller with all the necessary information.

The manual assumes that the reader has experience with astronomical CCD detector systems. It is not intended to be an introduction to CCD detector systems, and therefore it uses terminology common to this field (e.g. pixel, binning, readout, frame-transfer chip, etc.) without further explanations (for these see [5], [19] and [20]).

The manual also assumes that the reader has significant experience with the FIERA CCD Controller. In particular the Installation and Configuration of the FIERA Software is assumed to have been already performed (see [5]).

In addition to the Introduction, this manual contains the following chapters:

FIERA SPARC Update: how to install a new version of the VLTSW on a FIERA SLCU.

FIERA SPARC Hard Disk Backup: procedures to be followed to perform proper backup of the hard disk of a FIERA SPARC.

Trouble-shooting: list of already encountered problems and description of the possible reasons and solutions.

Reference: manual pages of some diagnostic programs.

The following table presents the complete list of documents available about the FIERA CCD Controller software, together with a summary of the contents and the category of users who may be interested in reading them.
