9030944 E10 Loading a Configuration
5-13
Device Landscapes, Buttons, Codes, and Settings
When Safe Load is off, on the other hand, ECM continues loading attributes
even if some or all of the attributes cannot be loaded until it has tried loading
them all.
Although Safe Load cannot make the load process fail-safe, it does make the
process safer. At most, with Safe Load on, you may have to manually restore
the configuration of one device if the rollback fails. However, with Safe Load
off, you take the risk of having to restore the configurations of dozens of
devices if the load fails.
Safe Load Default Setting
The Safe Load default setting (on or off) is set at installation.
However, during any ECM session, you can still turn Safe Load on or off by
clicking on the Safe Load option. This selection applies to loads performed
during the current session and to loads scheduled with the Scheduler during
the current session.
When you exit ECM and then open the application again, the Safe Load option
defaults to the value specified in the ECM Resource file, Ecm. If you want to
change this default, you can edit the ECM resource file. See Appendix B.
How Safe Load Works with One Device
When you load a configuration to one device, Safe Load works in this way:
1. Before loading a configuration, ECM captures the device’s configuration.
2. The next step depends on whether the capture is successful or not
successful:
• If the initial capture is not successful, ECM displays a “Capture for
Safe Load failed” error message and stops the load process. (The
configuration’s Load status is not modified.)
• If the initial capture is successful, ECM begins the load process,
loading each attribute one at a time.
3. If all the attributes load successfully, then the configuration is successfully
loaded and the procedure ends. However, if one attribute fails to load,
ECM stops the load.
4. Then ECM performs a second capture so that it can compare the initial
configuration to the current configuration.
5. ECM attempts to roll back (restore) the attribute values that were
changed.
6. The next step depends on whether the rollback is successful or not:
