Remove the PSU module by pulling the extraction handle
down. The extraction handle should gracefully disconnect the
PSU from the backplane connectors. Once dislodged, gently
pull the PSU module out of the system. If the system is
mounted in a rackmount rack, use another hand to support its
weight while removing the module.
Removing the PSU Module
WARNING!
Install the replacement module. Make sure the extraction
handle is held at its lowest position so that the saddle notches
on the sides of the handle can snap onto the metal anchor pins
on the interior walls of the PSU slot. Push the PSU into
chassis, and when you feel the contact resistance, pull the
handle upwards to secure the module.
