Caution – Only a qualified technician is allowed to perform this procedure. This

The Super FRU is a chassis containing the motherboard and certain

the CRUs from the old chassis. Then, re-install each of those components in the new
Super FRU chassis.
Note – The Sun Fire V40z Super FRU ships with the following components
installed: the PCI riser, the SCSI backplane assembly, the rear fan-cage assembly and
the operator-panel assembly.
You must remove all other CRUs from your old chassis and re-install them in the
new chassis. This includes the system cables.
1. Power off the server, including any attached peripherals, and disconnect the
