Removing and Installing a Power Supply Module
The two power supply modules (primary power supply and redundant power supply) are
identical. Each power supply module has a tri-color LED, visible on the front panel, that
indicates the status of the power supply outputs (see the
page 17 for LED indications).
ATTENTION:
Remove and replace a power supply as follows:

•
Disconnect both power supply cords before servicing.
Débranchez les deux câbles de la source d'alimentation avant l'entretient.
•
Do not touch the electronic components or the connectors on the backplane or
•
on the circuit boards without being electrically grounded. Handle circuit boards by
their edges only. Electrostatic discharge (ESD) can damage circuits, even if you
cannot feel, see, or hear it.
•
Ne pas toucher les composants électroniques ou les connecteurs sur la carte mère
ou sur les circuits imprimés sans être électriquement relié à la terre. Manipuler
les circuits imprimés en les tenant seulement par leurs bords. Les décharges
électrostatiques (ESD) peuvent endommager l'équipement, même si vous ne
pouvez pas le sentir, le voir ou l'entendre.
Use a screwdriver to rotate the left and right captive panel screws to completely loosen
the screws (see figure 59).
Gently, but firmly, pull on the screws to loosen the power supply from the backplane.
Slide the power supply out of the enclosure.
