Chapter 2: Upgrading Baseboard Components
1. Observe the safety and ESD precautions at the beginning of this chapter.
2. Remove the access cover.
3. Remove the front and rear foam covers.
4. Label and disconnect all internal cables connected to add-in boards.
5. Remove all add-in boards.
6. Label and disconnect all internal cables connected to the baseboard.
Note: The baseboard is attached to the electronics bay. In general, the best method for
removing the baseboard is to remove the electronics bay first, particularly in servers
mounted in a pedestal (tower) orientation, though this is not a requirement.
1. Open the front subchassis and, if necessary, remove the electronics bay.
2. Remove the processors and processor retention module.
3. Remove and save the two screws that secure the baseboard to the chassis.
4. Slide the baseboard toward the front of the server until the board’s I/O connectors
clear the rear of the chassis.
5. See Figure 2-1 for an example of removing the baseboard.
• The edge of the baseboard at the TOP of the figure (NEAREST and parallel to
the ISA slot) fits into a groove along the edge of the chassis.
• The edge at the BOTTOM of the figure (OPPOSITE and parallel to the ISA slot)
is free.
6. Place your fingersunder theedge of thebaseboardOPPOSITE theISA slot (theedge
at the bottom). Lift the edge a few inches.
7. Slide the baseboard out, toward the edge you just lifted. This will free the opposite
edge (nearest the ISA slot) from the groove that secures it to the chassis.
8. Remove the baseboard and place it component-side up on a nonconductive,
static-free surface or in an antistatic bag.
9. Remove and save the EMI gasket that covers the I/O connectors on the board.
