Replacing Parts
To remove the motherboard
Note: This procedure assumes that you have already performed the procedure “To remove motherboard components
from the motherboard” on page 60.
1 Remove the six mounting screws that secure the motherboard to the base of the chassis (see Figure 31 on page 59
for the screw locations on your motherboard).
To minimize tension on the motherboard, loosen all the screws partially before removing any one screw
completely.
2 Lift the edge of the motherboard opposite the connector panel to release the motherboard from the chassis, and
then gently lift the motherboard out of the chassis.
Note: Make sure to lift the edge of the motherboard near DIMM area, so that the underside of this area clears the
nearby screw standoff.
Make sure that the connectors on the motherboard clear the cutouts in the chassis as you remove the board. Avoid
handling contacts or using excessive force.
3 If you are replacing the motherboard with a new motherboard, remove the following from the old motherboard:
•
DIMM (see page 67 )
•
CPU (see page 69 )
Replacing the motherboard
Use the following procedure to replace the motherboard in the E-35A chassis. Failure to follow the instructions in this
section may corrupt the system (not easily repaired in the field) or result in an incomplete installation.
Troubleshooting cautions
•
Before deciding to install a new motherboard, refer “Troubleshooting” on page 103 .
•
Inspect all cables and internal components as described on pages “Checking external connections” on page 103 and
“Checking internal components” on page 104.
Important: Follow standard ESD and other safety precautions when handling the motherboard. Do not touch
the contacts and avoid using excessive force. Place the motherboard on a grounded, antistatic surface.
