Replacing Parts
2
Lift the motherboard edge opposite to 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 motherboard edge near the 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.

If you are replacing the motherboard with a new motherboard, remove the following from the old motherboard:
•
DIMM (see

)
Replacing the motherboard
Use the following procedure to replace the motherboard in the E-36A 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
•
Inspect all cables and internal components as described on pages
“Checking external connections”
and
“Checking internal components”
•
If troubleshooting strategies (checking cables and connections, reinstalling system software, and so forth) do not
solve the problem, and you suspect that the hard disk drive or the motherboard is faulty, always troubleshoot in the
following order:
•
First,
replace the hard disk drive and install system software.
Always replace a faulty hard disk drive with a new hard disk drive. Transferring a hard disk drive from one E-36A
to another is incorrect and strongly discouraged.
•
If the problem persists,
reinstall the original hard disk drive in the system, and then replace the motherboard.
Motherboard cautions
•
Do not
transfer the BIOS chip from the old motherboard onto the new motherboard.
BIOS chips are not interchangeable.
Troubleshooting in the wrong order will cause the system to malfunction. In general, it
is
highly
unlikely that both the hard disk drive and the motherboard are defective; therefore, avoid
replacing both to solve one problem.
If you have exhausted all other troubleshooting remedies and determined that you need to install a
new motherboard, be sure to observe the following cautions:
