Mitel 6800 Series SIP Phone Release 4.2.0 Administrator Guide
As software upgrades on the M680i are performed one at a time, each additional module
connected increases the approximate upgrade time (e.g. three connected M680i expansion
modules will take approximately 30 seconds to upgrade).
For the M685i, the upgrade process will take approximately 7 to 10 minutes, in which case an
upgrading icon will be displayed on the module's LCD screen and an upgrading message will
be displayed on the phone's LCD screen. If the upgrade is successful, the module's LCD screen
will refresh with the softkey images. If the screen is not refreshed after ~15 minutes, the upgrade
may have failed. In such scenarios, unplug and reattach the power source from the phone to
attempt the upgrade again.
Unlike the M685i, software upgrades for the M685i are performed simultaneously and therefore
do not increase the upgrade time (e.g. three connected M685i expansion modules will still take
approximately 7 to 10 minutes to upgrade).
When using a combination of modules in tandem, the process of upgrading should take
approximately 7 to 10 minutes as well.
