the Internet connection is slow and you must wait for all
the devices to complete the update process.

process to complete. You may prefer to schedule a system
update to take place overnight.
Update individual devices manually either through the
front panel or through the WebUI.
Power cycle each device that did not get upgraded.
Unplug the power cord and plug it back in. As each device
reboots, it automatically updates (if it detects updated
software in the system).
