Chapter 7: Using SmartPath EMS
When updating SmartPath APs in a mesh environment, the SmartPath EMS communicates with mesh points through their portal
and, if there are any intervening mesh points, through them as well. While updating SmartPath APs in such an environment, it is
important to keep the path from the SmartPath EMS to all SmartPath APs clear so that the data transfer along that path is not
disrupted. Therefore, when updating a firmware image or configuration on SmartPath APs in a mesh environment, make sure that
the portal or a mesh point closer to the portal does not reboot before the upload to a mesh point farther away completes.

Figure 7-16. SmartPath APs in a mesh environment.
To avoid the reboot of an intervening SmartPath AP from interfering with an ongoing upload to a mesh point beyond it, allow
enough time for the firmware to reach the farthest mesh points before activating the firmware. After all the SmartPath APs have
the firmware, rebooting any SmartPath APs between them and SmartPath EMS becomes inconsequential.
