9-17 MINI-LINK BAS
EN/LZB 111 0542 P2B Technical Description
9.7.1 Install SW Upgrade File
The new configuration files containing the new baseline and the new
software files are installed in the CP file system.
9.7.2 Download Modules
Based on the HW-SW relationships contained in the baseline
configuration files, the download procedure is started. The system will
transfer on the passive memories of all the upgradable boards, DPs
and BC, the loadmodule of the new baseline in order to prepare it for
the upgrade.
After the load module has been downloaded the CRC-16 is verified; if
the check fails, a retransmission is started.
9.7.3 Install New Management System
This operation is optional and implies an upgrade of the EM software.
Backward compatibility for all the functions involving equipment
handling and software upgrade is guaranteed.
9.7.4 Stop CP
The CP needs to be stopped.
From now on, no O&M actions on the system are possible. However,
this doesn’t imply any traffic interruption.
9.7.5 Install New CP Software
Also this operation is optional and is executed only if the CP software
itself is being updated.
9.7.6 Upgrade Network Database
If the new baseline implies software modifications impacting on the
network database structure, a proper update is automatically executed
to generate a database version with the structure required by the new
software. The old database version is always saved in a back-up copy.
All configuration data is maintained and adapted to the new database
structure.
