Removing the Memory Board DC-to-DC Converters

The Memory Board DC-DC Converters reside on the side of the Processor/Memory Complex inside
the system chassis. The server uses four converters to supply regulated power to the system. You can
access them by removing the Processor/Memory Complex and working from its side. The Memory
Board DC-to-DC Converters must be removed before the Memory Board can be replaced.
To remove the converters, complete the following procedure:
1. Observe the necessary safety and ESD precautions.
2. Remove the Processor/Memory Complex as described in "Removing the Processor/Memory
Complex" in Chapter 5.
3. Loosen the slide clamp screw that secures the converters but do not remove it. Loosening the
upper screw allows you to remove the upper converters, while loosing the lower screw allows
you to remove the lower converters.
4. With the converters to be removed located on the top of the unit, slide the clamp upward that
secures that pair of converters.
5. Pull each converter straight out from its socket. Be sure that you keep the converter level as
you remove it from its socket. Each converter has a keyed guide that is attached to the side of
the Processor/Memory Complex.
