10.2.7 Running an Actions.txt file from a USB Memory Stick
If dual controllers are fitted to the router, the inactive controller should be updated first. This
can then be made the active controller, and the other controller (now inactive) can be
updated. If a single controller is fitted it must be updated while it is Active.
1. Eject the bootable USB memory stick from the computer.
2. When working on a dual controller system locate the Idle Nucleus2 controller, see
Table 24. for LED positions:
LED 1:
Idle = Flashing Blue
Active = Flashing Green
Check that LED 1 confirms the Nucleus2 controller is idle.
3. Insert the USB memory stick in the USB connector on the front of Idle Nucleus2
controller (see Table 24.).
4. Press the Reset button on the Nucleus2 controller fitted with the USB memory stick
(see Table 24.).
• On a dual redundant controller system the router controllers can be updated while
the router is on-air, if required.
• If the router only has a single controller the upgrade can be performed while the
router is on-air but all communication with the router controller will be lost during
the upgrade. Because of this the crosspoints cannot be switched and tallies are not
reported during the upgrade. Video and audio processing is unaffected.
• Ensure that all of the required files are on the bootable USB memory stick and that
the Actions.txt file contains the correct actions for the Nucleus2 controller update.
For details see the tables in section 10.2.2 and 10.2.3.
If the router is only fitted with a single controller the controller will be active and the USB
memory stick should be plugged into that controller.
