Replacing a Console Power Supply
The control surface is powered by dual-redundant power supplies which are fitted inside the frame behind the
TFT display:
The two supplies come as a complete "PSU block" which can be replaced in its entirety - i.e. it is not possible to
replace an individual supply.
Depending on the console size, more than one block may be fitted to the frame. Double-click
here
to view all the
possible frame variants and PSU block locations (as a pdf).
To replace a PSU block you will need to remove the TFT display from the PSU bay.
1.
Turn off the power to the control surface by
ALL
MAINS
connectors - press the red button
on the IEC connector to release the plug.
You must remove the
MAINS
connectors from the frame, rather than from the wall, as the IEC sockets form
part of the PSU module. If you do not, then the PSU module will get stuck during step 7.
2.
Locate the PSU bay and remove its TFT display as described
. You will see the PSU block and
Bay Server mounted at the rear of the frame.
3.
Using a T20 Torx driver, disconnect the PSU block from its distribution board by loosening the 8 screws
shown below.
Take care NOT to disconnect the lower cables/screws:
