To insert a power supply:
1. Position the power supply so that the red release latch and handle are on the left-hand side.
2. Slide the power supply into its slot until the latch clicks in place. The Engine will automatically detect the
new unit.
Installing a Redundant Controller
You can order and install a redundant Controller for an Avid NEXIS Engine or the Avid NEXIS | SDA. You can
install the redundant Controller at any time, even if the Engine or Avid NEXIS | SDA is already mounted in a
rack.
For highest availability, Avid recommends installing a redundant Controller in all the Engines and Avid NEXIS |
SDA, if applicable, in the entire shared storage system. However, you can install a redundant Controller in the
Avid NEXIS | SDA alone, to ensure the System Director fails over if a Controller fails.
n
Avid NEXIS | PRO and Avid NEXIS | E2 SSD do not support redundant controllers.
Repeat this procedure for each Engine and the Avid NEXIS | SDA if applicable.
To install and use a redundant Controller:
1. Upgrade the Engine or the Avid NEXIS | SDA to at least v6.1. See the Avid NEXIS Administration Guide for
more information on upgrading your system.
Avid NEXIS v6.1 is the minimum release to support redundant Controllers.
2. Open the Agent and go to the CONFIGURE tab.
3. Enter the IP address for the redundant Controller before you physically install it.
4. Remove the blank plate covering the empty Controller slot.
5. Install the redundant Controller as follows:
a. Open the release latch on the new Controller all the way.
b. Note the correct orientation of the Controller for the system you are adding it to:
- In the 2U chassis the redundant Controller is installed upside down. See “Avid NEXIS | E2, Avid
NEXIS | E2 SSD, and Avid NEXIS | SDA Rear View” on page 5.
- In the 4U chassis the redundant Controller is installed right side up, in the third slot from the top
(leaving a one-slot gap between the first and redundant Controllers). See “Avid NEXIS | E4 Rear
View” on page 6.
- In the 5U chassis the redundant Controller is installed in the right-hand slot. See “Avid NEXIS | E5
Rear View” on page 10.
c. Slide the replacement Controller into its slot until it will go no further.
d. Close the lever until it clicks in place.
The Controller engages with the connector on the midplane.
e. Check the Power/OK LED on the Controller to make sure it is lit; see “Controller for Avid NEXIS E-
Series, System Director Appliance, and Avid NEXIS | PRO with 4TB Drives” on page 14 for more
information.
6. Connect the two Controllers with the supplied cable between the ports indicated in the following figures. The
cable provides ongoing communication between the Controllers and must remain in place.
