Load concept for HG 3500/HG 3575

• The loadware for HG 3500/HG 3575 is loaded via HTTPS (see Section 5.4, “Updating Loadware with Web-Based Management” and Section 5.5, “Updating Loadware with "LW Update Manager"”).
• Loadware can be loaded in the background during normal operation, that is the activation of new loadware can be delayed (until off-peak hours). The new loadware should nevertheless be activated as quickly as possible to avoid problems.
• Optimized loading for HG 3500 gateways
• As the common gateway development has combined the software of all previous gateways (HG 3530, HG 3540, HG 3550 and HG 3570) in a single software/loadware package, the size of the software has increased accordingly. This has increased the loading time to approximately 15 minutes. The load concept for STMI loadware was adapted in response to this change.
  There are two CGW-STMI2 boards and two CGW-STMI4 boards. These boards all have a different HW ID but have the same loadware file.The optimized methodology for CGW-STMI boards means that the loadware file is only downloaded once for these boards, even if they have different HW IDs.
  This results in the following implementation scenarios:
  • Configuration featuring both STMI4 types and an STMI2 type => loadware file is only transferred once and then distributed to all corresponding boards.
  • Configuration featuring both STMI2 types present => loadware file must be transferred twice because the STMI2 firmware can no longer be modified.
  STMI4 boards must have at least the firmware STMI4_FW_070725 in order to use the optimized load concept for the different CGW-STMI boards.
