Limitations for the Upgrade
Incomplete ESW selection for the upgrade will lead to incompatibilities and service interruptions, and can even lead to the loss of the management connection.
→ If you miss a unit that needs to be upgraded the old unit ESW will be incompatible with the new ESW of the upgraded units. Therefore always select all units for upgrade that are operated in your NE as listed in Table Upgradeable Units and ESW with System Release R17A before executing “Download and Start…” or “Start…”.
Please note that the upgrade procedure will interrupt services for up to a few minutes.
→ If you do not want services to be interrupted at the moment, do not perform the upgrade now but choose a time for the upgrade when the impact of service interruptions on customers is minimal.
→ As an alternative you may want to download the new ESW to the FOX61x without installing the new ESW and without re-starting the units yet. This reduces the risk of a failed upgrade. Also see steps 8. to 11. in the following procedure, but selecting “Download” in step 11., and only select “Start…” after all ESW files have been downloaded. Note: The open “Software Download” dialog blocks any further FOXCST action.
Please note:
The ESW upgrade for the SENC1-4, SENC1F4, SENC1-8, and SENC1F8 encryption units cannot be done with the procedure described in section Step-by-Step Procedure.
→ For a description of the SENC1-4, SENC1F4, SENC1-8, and SENC1F8 units specific ESW upgrade procedure please refer to [1KHW029028] User Manual “SENC1-4, SENC1F4, SENC1-8, SENC1F8”.
Please note:
The risk of failed upgrades can be further reduced by running only one FOXCST instance on one PC.
