AutoSave System

This field enables or disables the AutoSave system. Please note that there will be a 5 minute
delay after initial power-up of the SCU before an AutoSave operation will be performed. This is
to allow sufficient time for the shelf and provision settings on the SCU and Modules to stabilize.

AutoSave Only If Prov Changes

This field allows the administrator to reduce the number of redundant AutoSave operations and
SCA files on the TFTP server by instructing the SCU to perform Autosave operations only if
provisions have been changed on the SCU or an installed module.
AutoSave Filename Prefix, AutoSave Filename Suffix, and Max AutoSave
File Instances
These three fields are collectively used to construct the name of the AutoSave SCA file on the
TFTP server.
The AutoSave filename prefix is a 0 to 30 character string that will be used to construct the first
part of the SCA filename.
The AutoSave filename suffix is a 0 to 8 character string that will be used to construct the
trailing type, or extent portion of the SCA filename. If a period between the first and second part
of the SCA filename is desired, it should be placed within this suffix field.
The max AutoSave file instances field determines the maximum number of SCA filenames to
save to the TFTP server. This is often called a backup file rotation scheme, where the last "n"
files are always maintained on the backup medium (the TFTP server in this case). For example,
if this field is set to a value of seven (7), seven uniquely named SCA files will be written to the
TFTP server. After the seventh file has been written, the count will recycle to one (1), and the
first file will be overwritten. The sequence 1 to 7, 1 to 7, 1 to 7 will be continually cycled through
until the value of this field is changed, at which time it will be reset to one (1).
The generated SCA filename will be of the form (prefix)_(instance)(suffix), excluding paren-
theses, where:
• "prefix" is the value of filename prefix field;
• "instance" is decimal number between 1 and the max AutoSave instances field; and
• "suffix" is the value of the filename suffix field.
For example, if the prefix is "Flintville," the next AutoSave file instance is 2, and the suffix is
".sca", the name of the next SCA AutoSave filename will be "Flintville_2.sca".

AutoSave Time

This field represents the time of day after which the AutoSave SCA file can be written to the
remote TFTP server. These fields allow the administrator to configure the MX2820 shelves on
the customer network to write their AutoSave SCA files at different times so as to prevent
network congestion that might occur if all the shelves attempted to save their SCA files at the
same time.
If, for example, the AutoSave Time was set to "03:15", the SCU would attempt an SCA AutoSave
operation shortly after 03:15 in the morning.
