About Controller Failures
When a Controller fails, the fault LED will be lit red. If the Engine has two Controllers, services that
were running on the failed Controller will move to the operational Controller. This process can take
three to five (3-5) minutes on 2U and 4U Engines and the SDA, and 10 or more minutes on 5U
Engines.
In an Engine with a single Controller, clients cannot access Workspaces until the Controller is
replaced.
c
In an Avid NEXIS | E5 or Avid NEXIS | E5 NL with a single controller, insert the replacement
controller in the same slot as the original factory-installed controller; by default, slot 0, or the
slot on the left of the Engine looking at the rear.
c
Both Controllers in an Engine must be the same type, with the same label. See
Controllers” on page 13
for more information. In particular, make sure that both Controllers
in an Engine have the same amount of memory. Installing Controllers with different memory
capacities in the same Engine is not supported.
n
Make sure you have a replacement before removing a failed component. When replacing a Controller
while the system is running, insert the new Controller within two minutes of removing the defective
Controller.
Replacing a Controller
To replace a Controller:
1. Make note of the locations of all cables (between the two Controllers, if applicable, and to the
switch) and disconnect them from the failed Controller.
2. Pinch the latch on the Controller and pull the handle toward you.
The controller disengages from the connector on the midplane.
3. Pull the Controller out of the Engine.
4. Hold the replacement Controller in the same orientation as the one you removed.
5. Open the release latch lever all the way.
6. Slide the replacement Controller into its slot until it will go no further.
7. Close the lever until it clicks in place.
