Notes:
1. Some 802.3at switches require connected devices to send power allocation requests
in excess of 12.95 W using LLDP. Therefore, Mitel recommends that Administrators
ensure LLDP is enabled when powering a 6873i SIP phone with one or more
expansion modules connected using Power over Ethernet plus (PoE plus). For more
information on LLDP, see
(LLDP-MED) and Emergency Location Identification Number (ELIN)"
2. For the 6873i, the USB port on the phone will be disabled if the phone is being
powered using 802.3af PoE and one or more expansion modules are connected.
Use the recommended AC adapter (optional accessory) or power the 6873i using
802.3at PoE plus to ensure the USB port will be functional when expansion modules
are connected to the phone.
M680i and M685i Software Upgrades
The M680i and M685i do not require separate firmware packages. M680i/M685i software is
embedded within the respective phone's firmware package.
When the M680i or M685i is connected and is powered up (for the M680i the LED corresponding
to the second button will turn solid red indicating it is powered up; for the M685i the LCD screen
will turn on) the module will check to see if an upgrade is required. If it does not have the latest
software, the module will upgrade itself using the phone's embedded firmware.
For the M680i, this process will take approximately 10 seconds, in which case the LED
corresponding to the second button will stay solid red for the duration. If the upgrade is
successful, the LED will turn green. If the LED stays solid and red for longer than 10 seconds,
the upgrade may have failed. In such scenarios, unplug and reattach the power source from
the phone to attempt the upgrade again.
