Do not run the frame for extended periods of time with one of the power
supplies removed or with the door open. Proper cooling of the frame requires
both power supplies to be inserted into the frame, or one power supply and a
power supply fan module.
The EMX3-FR & EMX6-FR 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.
In the case of the EMX6-FR, the redundant power supply is required to provide adequate cooling to the
frame so it is always recommended.
On EMX3-FR frames with only one power supply, a blank power supply fan module with cooling fan
(properly rated for the wattage of the power supply) must be inserted into the second power supply
space. The blank power supply fan module contains a module cooling fan sufficient to cool the maximum
power dissipation of the frame and baffles to maintain proper airflow within the frame.
The power supply is secured into the frame by a machine screw through the rear panel. This screw must
be removed before the power supply can be extracted from the front.
To reduce risk of electric shock you must replace the mounting screw after
replacing the power supply.
To replace the power supply the following procedure should be used for the EMX6-FR and EMX3-FR.
1. Turn off the power supply switch.
2. Unplug the power supply
3. From the rear of the frame locate the power supply mounting screw. This screw is the top right screw
holding the fan guard in place, and is indicated by the legend
PSU
Mount
4. Remove the power supply mounting screw.
5. Open the front door of the frame and pull the power supply out of the frame.
6. Reinsert the new power supply into the frame taking care that it is properly aligned with the card
guides. Press firmly to make sure that the power supply is fully seated into the rear panel connector.
7. Reinstall the power supply mounting screw from the rear of the frame.
8. Plug in the new power supply power cord
9. Turn on the power switch for the power supply. After a few seconds you should see the PSU STATUS
LED come on indicating that the power supply is working correctly.
10. Once you have confirmed the power supply is working correctly, close the front door of the frame.
To replace the power supply the following procedure should be used for the EMX1-FR.
1. Turn off the power supply switch
2. Remove AC power cable
