5.2.7 Removing the Motherboard Assembly
The motherboard for your server has two distinct boards for the CPU and the I/O
board. However, they must be removed and replaced as a single motherboard
assembly (
FIGURE 5-11).
Caution – Remove and replace the motherboard carefully. The motherboard rests
on metal standoffs. If the motherboard is not handled carefully, the components
mounted on the underside of the motherboard can be damaged if they hit the
standoffs. To ensure that this damage does not occur, perform the removal and
replacement instructions described in this document.
Caution – A flexible cable connects the CPU and I/O boards. This flexible cable is
fragile. Handle these parts very carefully to prevent damage.
Caution – This procedure requires that you handle components that are sensitive to
static discharges that can cause the component to fail. To avoid this problem, ensure
that you follow antistatic practices as described in Section 5.1.6, “Performing
Electrostatic Discharge Prevention Measures” on page 5-6.
