10.2.2.8. Updating Access Point Loadware during an RMX Upgrade
(New Fix Release/Minor Release) 
The feature "AP multicast loading" lets you perform simultaneous
loading operations for multiple access points. Originally, simultaneous
loading operations were only possible for access points containing boards
that already featured the latest loadware. With “AP multicast loading”
it is also possible if the boards need new loadware.
Procedure
- Use the traditional FTP solution to transfer the new loadware for the HG 3575 to the access point (up to five access points per run). See also Section 2.2.7, “Loading new Loadware on a HG 3575”.
-
Once the new loadware has been successfully transferred and activated, the TCP/IP connection is re-established between the host system (HSR) and the access point.To transfer the loadware downloaded in the background to the NCUI a warm boot is initiated and executed.The restart (warm boot) with the new loadware is followed by a golden loadware check. If this golden loadware check fails, the NCUI restarts with the old loadware and the new loadware (HD) is retransmitted.
IMPORTANT:
This step is skipped if there is no new loadware available for the HG 3575. - The loadware transfer for the peripheral boards starts.
- The access points are entered in the load list once the loadware has been transferred.
- The first access point in the load list is put into full operation immediately (takes approx. 15 minutes). While this access point is being put into operation, other access points that have already completed the loadware transfer/activation are entered in the load list.
- As soon as the first access point has gone into operation, all access points that have been entered in the load list in the meantime are simultaneously loaded and put into operation.
IMPORTANT:
In the past, the APs in the load list were processed
or put into operation in sequential order.
- While these access points are being put into operation, other access points that have completed loadware transfer/activation are entered in the load list.
- As soon as the access points have gone into operation, all access points grouped together on the load list are put into operation simultaneously.
- These procedures are repeated until all access points have been upgraded.
