Sun Fire V20z and Sun Fire V40z Servers—User Guide • March 2005
3.4.1 Versions of the Sun Fire V20z Server
A number of different versions of the Sun Fire V20z server have been released. Due
to changes on the motherboard as well as in the BIOS and firmware, a number of
components—such as memory VRMs and CPU VRMs—are not interchangeable
among the various releases.
The chassis part number (PN) is labelled on the front panel of the server, near the
CD-ROM/DVD-ROM/Diskette Drive assembly.
TABLE 4
explains the components available for each of the server releases.
