Replacing Power Supply Modules
In the event of a power supply failure, the unit will switch to the redundant power supply
for its power source. An alarm will appear on the Kaleido-X output screen, until it is
manually reset through the Kaleido Software. It is not necessary to turn off the unit before
replacing the defective power supply.
The faulty power supply will show a red FLT lamp on its front panel.
The Kaleido-X is powered by dual redundant power supplies. These are installed at the top
of the frame above the cards. The supplies are installed and removed from the front of the
frame and are hot-swappable, so that a defective supply may be replaced without
removing the Kaleido-X from service.
Access the power supplies by opening the front door of the frame. The two power supplies
are located at the top, above the card slots. Viewed from the front of the frame, PSU A is
located on the left-hand side, and PSU B is located on the right-hand side.

power supply and you must ensure the supply is grounded before
connecting your system.
• If you have a frame model KXA-FR7 then you need the KXA-PSU-7 power
supply.
