5.2.2 Removing the CPU1 and CPU2 Power Cables
The CPU1 and CPU2 power cables bring power from the power distribution board where they are
soldered on to the CPUs (and their DIMMs). The cables are routed along the fan cage just behind the
support cross bar. They are covered by a protective black insulator. The CPU1 cable connects to the
server board in the right front corner. The CPU2 cable is routed through another black insulator along the
right chassis wall. The CPU2 connector on the baseboard is at the rear right side of the board.
The CPU power cables must be disconnected on the server board side and pulled out of the way before
some other components, such as the front panel board, the power distribution board, and the server
board can be replaced.
To disconnect the CPU1 and CPU2 power cables:
1. Power down the server and remove all peripheral devices and the power cord(s)
2. Remove the chassis cover. For instructions, see “Removing the Chassis Cover” in Section 3.2.
3. Remove the right-side slot 5 riser card assembly. For instructions, see “Removing a Riser Card
Assembly” in Section 3.2.
4. Remove the processor air duct. For instructions, see “Removing the Processor Air Duct” in Section
3.2.
5. Carefully uncover the black insulator covering the CPU 1 and CPU 2 power cables behind the fan
cage. (Figure 46)
6. Disconnect the CPU power cables from the server board and pull them out of the system.
(Since they are soldered onto the power distribution board, you cannot remove them from the chassis,
