•
This chapter only describes how to update the loadware for gateway boards.
•
To update the system as a whole, use the conventional HiPath 4000 Assistant
features Software Transfer (SWT) and Software Activation (SWA).
•
To minimize system downtime, you can upgrade the gateway boards first with
the load concept described below and then upgrade the system with the
Software Transfer (SWT2) and Software Activation (SWA) functions.
•
For more information on how to update the system as a whole, see
"Implementation Scenarios for Features > Updating HiPath 4000 System
Software".
•
Although you can store two loadware images on the IP gateway HG3575,
only one of these is the "golden load" that is loaded after a cold start (power
off).
•
Loadware ID check
A loadware ID check is performed every time the HG3575 is started and
compares the board loadware that is being downloaded with the loadware
version on the hard disk (:PDS:APSP/LTG/LGA0/PZKNCI40).
If the result of the check is negative, that is, if there is a discrepancy with the
loadware stored on the HD, then the loadware is transferred from the HD to
the NCUI via FTP and then installed/restarted.
•
Golden loadware check
In HG3575, the latest loadware to be downloaded is called "golden loadware"
(as-delivered NCUI2+/NCUI4 boards include loadware in the flash memory).
The golden loadware check is always performed after new loadware is
downloaded/restarted (loadware upgrade/loadware ID check negative). If this
check is successful, the download pointer is rewritten as appropriate so that
the golden loadware corresponds to the new loadware.
