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.
