Replacing the Quantum Ultra®Power Supplies
The Quantum Ultra has a primary and a redundant power supply unit (PSU) to ensure continued,
uninterrupted operation if a power supply should fail. However, if a power supply does fail, you should replace it as soon as
possible. The power supplies are hot-swappable, that is, one can be replaced while the unit is operating with the other PSU
supplying power.
NOTE: For full installation, configuration, and operation details, see the Quantum Ultra User Guide, available at
www.extron.com.
To replace either Quantum Ultra power supply:
1. Using a screwdriver or other tool, loosen the two thumbscrews on the power supply and the two thumbscrews on the
protective cover panel (see gure 1, 1).
ATTENTION:
• Thumbscrews should be tightened with a tool after both initial installation and subsequent access to the panel.
• Les vis doivent être serrées avec un outil adapté après la première installation et l’accès postérieur au panneau.
NOTE: The thumbscrews cannot be removed completely.

4. As you rotate the lever, the power supply slides to the right. If necessary, continue sliding the PSU to the right as far as
possible (see gure 2, 1).

6. Slide the new power supply into the empty slot vacated by the old PSU, until its back panel is at against the back wall of the
power supply compartment.
NOTE: There are two keyhole slots in the back wall and one on the front surface of the power supply compartment. The
power supply has three protruding pegs (see figure 3, 1).

Figure 3. Pegs on the Back of the Power Supply
These pegs must be in the slots on the back wall and front surface of the power supply compartment when you slide
the power supply all the way in. Otherwise, the power supply does not lie at against the back of the compartment, the
levers cannot lock the PSU in place, and the supply does not function.
If the power supply is in place, its front panel is ush with the front panel of the other power supply. If the new power
supply is not even with the other one, slide the new one out again and lift it up slightly as you slide it in again, until it
touches the back of the compartment.
7. When the power supply is in position, slide it to the left as far as you can without forcing it.
8. Ensure that the round end of the locking lever on the power supply (see gure 4, 2) is positioned between the two pegs (1),
located on the chassis above the power supply, then rotate the lever to the left until the power supply is locked in place.

9. Use a tool to tighten the two thumbscrews on the power supply as follows:
a. Grasp the screw rmly and press it inward.
b. Continue to press inward as you turn the screw to the left, until it is securely in place.
10. Reattach the protective cover panel.

Replacing the Redundant Power Supply
Replacing the redundant (bottom) power supply requires some steps to be performed prior to the procedure described in the
previous section. The primary and redundant power supplies are essentially the same unit, but they are congured slightly
differently in order to t into their slots in the chassis.
The replacement power supply kit is shipped with the power supply congured to replace the top (primary) PSU. If the lower
(redundant) power supply needs to be replaced instead, you must recongure new PSU so that its front plate (containing the
latch, handle, and thumbscrews) switches places with the metal strip on the power supply back panel.
To recongure a primary power supply as a redundant supply:
1. Perform steps 1 through 5 of the primary power supply replacement procedure, starting on page 1, to remove the redundant
power supply from the chassis.
2. Remove the front plate containing the latch, handle, and thumbscrews by unfastening the three round-headed Philips screws
at the bottom of the plate (see gure 5). (Retain these screws to reattach the plate in step 4).
Remove three screws.
Figure 5. Removing the Plate from the Power Supply Front Panel
3. Remove the metal strip from the back of the power supply by unfastening the three at-headed Philips screws (see gure 6).
(Retain these screws to reattach the strip in step 5).

Remove three screws.

4. Attach the front plate to the three holes at the bottom of the back panel using the three round-headed screws removed in
step 1.
5. Attach the metal strip to the three holes at the bottom of the front panel using the three at-headed screws removed in
step 2.
NOTES:
• When you have completed this procedure, the former front panel of the new redundant power supply becomes the
back panel, and vice versa.
• Note that the connector pins on the right side of the power supply that were formerly located near the top of the unit
(when viewed from the rear, see gure 6, 1) are now near the bottom.
6. Perform the remaining steps of the primary power supply replacement procedure, starting with step 6 on the previous page.
