For example, to write the machine serial number to the system board when the serial number is
"13-FEDCB" and the node name is "ZYXW3," you would issue the following command:
writesernum –sernum 13FEDCB ZYXW3
Note: The node will restart as soon as the serial number has been written to it.
Replacing the SAN Volume Controller 2145-8A4 system board
All the components that were removed when you removed the system board are reused during the
installation of the new system board.
Ensure that you have a monitor and USB keyboard available because they are required during this
procedure. You also need a power cable so that you can turn on the node while it is out of the rack.
Note: When you reassemble the components in the server, be sure to route all cables carefully so that
they are not exposed to excessive pressure.
Perform the following steps to install the system board:
1. Align the system board with the chassis, and replace the eight screws that you removed
2. Orient the microprocessor retention module as shown in Figure 292.

screwdriver. Tighten the screws only until they are snug, and then tighten them an additional
quarter turn.
3. Replace the microprocessor retention module. Gently secure it with the four screws that you
removed.
