Motherboard

To remove and replace the motherboard, proceed as follows.
Caution – Use an antistatic mat when working with the motherboard. An antistatic
mat contains the cushioning needed to protect the underside components, to prevent
motherboard flexing, and to provide antistatic protection.
Note – If the motherboard is being replaced, remove all DIMMs, UPA graphics
cards, PCI card(s), audio card, and CPU module prior to removing the motherboard.
Note the chassis slot location for each DIMM, UPA graphics card, and PCI card prior
to removal.
Note – The NVRAM/TOD contains the system host identification (ID) and Ethernet
address. If the same ID and Ethernet address are to be used on the replacement
motherboard, remove the NVRAM/TOD from the motherboard and install the
removed NVRAM/TOD on the replacement motherboard after motherboard
installation.
