Replacing the DC Power Supply Unit on
the SmartZone 300
When a power supply unit (PSU) on the SmartZone 300
fails, obtain a new PSU from Ruckus and replace the
faulty PSU. You can tell if a PSU has failed if its status LED
is red and it is emitting long, recurring beeps.
NOTE: The PSU is hot pluggable; you do not need to
power down the controller before replacing it.
DANGER-QSG: The PSU may be hot! Exercise caution when
touching the PSU.
1. Locate the PSU that must be replaced.

4. Hold the lock, and pull the handle of the PSU away
from the chassis to remove it.
5. Remove the replacement PSU from its antistatic
packaging, and verify that there is no visible damage
to it.
NOTE: If you notice any visible damage, contact
Ruckus Support.
6. Remove the protective cover over the DC power
supply connector on the rear of the unit.
7. Insert the replacement PSU (in the same orientation
as the PSU that you removed) into the bay. When the
module is fully seated in the bay, the PSU lock
automatically slides to the right to lock the PSU in
place.
8. Reconnect the power connector until it is fully seated.
