Replacing The Power Supply - evertz EMX3-FR User Manual

2.6.2. Replacing the Power Supply

Each power supply is a complete assembly, and includes the power supply cooling fan and one frame-
cooling fan. In the event that the power supply or one of the fans malfunctions, you will need to replace
the power supply assembly with a spare one while the failed assembly is being repaired.
CAUTION: Do not run the frame for extended periods of time with one of the
power supplies removed. Proper cooling of the frame requires both power
supplies to be inserted into the frame, or one power supply and a power supply
blank panel.
The 3000PS, EMX6-PS and EMX3-PS power supplies are hot swappable and can be easily replaced from
the front without interrupting the signal integrity of the frame. Each power supply is capable of supplying
full power to the frame by itself, however we recommend running with both supplies powered for power
redundancy. On frames with only one power supply, a 7800PS-QT-FM blank power supply module with
cooling fan must be inserted into the second power supply space. The 7800PS-QT-FM contains a
module-cooling fan and baffles to maintain proper airflow within the frame.
The power supply is secured into the frame by two machine screws through the rear panel (as shown in
Figure 2-41). These screws must be removed before the power supply can be extracted from the front.
