APPENDIX D: UPDATING FIRMWARE
104
5 Scroll down to the bottom and click Update
from File.
6 Locate the file on your hard drive and click OK
to start the update.
7 Follow the on-screen instructions.
8 IMPORTANT: disconnect the Ethernet cable
from your MOTU interface after you complete the
update, unless it's connected to a MOTU AVB
switch or other AVB-aware switch. If so, you can
leave it connected.
Updating multiple interfaces on a network
If you have two or more MOTU interfaces on a
network, you can update their firmware all at once.
1 Go to the MOTU Discovery Settings menu.

Viewing the latest firmware version
information
You can confirm the firmware version at the
bottom of the Device tab (Figure D-5).
Why does the firmware update require a
network cable?
Firmware updating was designed to use Ethernet
mostly for convenience. If you have lots of
networked devices, you can upgrade them all from
a distance (even over Wi-Fi) without having to plug
in directly and without having to download or run
an updater application.
This approach was also taken for engineering
reasons, with reliability foremost in mind. When
installing an update, the device reboots into a
stripped-down recovery partition to guarantee
that the update process can always be completed,
even if the power goes out mid-update. Since
updates can also affect the Thunderbolt or USB
chips, they cannot be used during the update.
