Preface
ATTENTION ! A reset should only be performed if a CTP card failure is
indicated. Do not reset a managed product unless directed to do so by a
procedural step or the next level of support.
ATTENTION ! This procedure deletes all data from the C: hard
drive partition.
ATTENTION ! Contents of the data directory are backed up to the

is not being written to or read from the CD-RW drive before removing the
CD. Removing the CD during a backup or restore operation can corrupt data.
