Component Replacement Procedures
Removing and Replacing a PSU (ES3301-2 only)
In the event of a PSU failure, an audible alarm will be triggered and the POWER indicator will show
red. Also the normally-lit status indicator on the faulty PSU will be extinguished. The alarm will
continue to sound until the fault condition has been removed.
A failed PSU can be removed and replaced without needing to power-down the VN-QUANTUM or
remove it from a rack (‘hot-swapping’).
NOTE: Disconnecting or powering-off a healthy PSU at any time will also sound the alarm.
Always use an Electrosonic Replacement PSU, Part No. ES3301-P.
Open the lower access panel by turning the latch knob a quarter-turn clockwise.
Remove the retaining screw and withdraw the faulty PSU using the handle provided.
Insert the replacement PSU and secure with the retaining bolt.
Switch on the new PSU.
Check that the status indicator is lit and that the alarm is reset.
