Replacing Processor Board Dc-To-Dc Converters; Removing Dc-To-Dc Converters From The Processor Board - Intel SR870BN4 - Server Platform - 0 MB RAM Product Manual

Replacing Processor Board DC-to-DC Converters

The DC-to-DC converters are located on the both sides of the processor board. The server uses
three DC-to-DC converters. One 3.3 V converter resides on the primary side of the processor
board, and two 3.3 V converters reside on the secondary side.

Removing DC-to-DC Converters from the Processor Board

1. Observe the safety and ESD precautions described in "Warnings and Cautions" on page 179.
2. Power down the system by pressing and holding the power button on the front panel for several
seconds. Unplug both AC power cords to remove standby power from the server.
3. Remove the processor/memory module as described in "Removing the Processor/Memory
Module" on page 207.
4. Position the processor/memory module so that the primary or secondary side faces up as
required.
5. Open the processor/memory module.
6. Press downward on the two latches that secure the DC-to-DC converter (A in Figure 101).
7. Pull the DC-to-DC converter straight out from its connector (see arrow B in Figure 101). Be
sure to keep the converter level as it is removed from its connector.
