Power Supply LEDs
When you encounter a problem with the power supply, check for:
•
Missing or damaged power cords
•
Incorrect or ungrounded circuits
•
Proper power is supplied to the Engine

When the Engine is turned on, all LEDs are lit for a short period to ensure that they are working.
This does not indicate a fault unless the LEDs remain lit after a few seconds.

Replacing a Power Supply (2U and 4U)
The power supplies in the 2U and 4U chassis include cooling fans as well as supplying power to the
system. The power supplies are bi-directional; you can insert a power supply into either the left or
right slot. When installed on the left side of the Engine, the plug is below the ON/OFF switch. When
installed on the right side, the plug is above the ON/OFF switch.
To remove a power supply:
1. Open the strain relief and unplug the power cord.
2. Press the black release latch (see
) towards the center of the
module.
3. Open the silver latch, which disengages the power supply module from the Engine.
To insert a power supply:
1. Position the power supply so that the release latch and handle are closest to the Controller.
2. Slide the power supply into its slot and close the handle until the latch clicks in place.
3. Reconnect the power cord and secure the strain relief.
Replacing a Cooling Module (5U only)
In Avid NEXIS | E5 and Avid NEXIS | E5 NL, the cooling modules are separate from the power
supply. These Engines are designed to continue working with at least two of the five cooling
modules.
