CHAPTER 1
Upgrade Overview
This document provides procedures for preparing Sun Fire™ E4900 and Sun Fire
6800/4800 systems to accept the UltraSPARC®IV/IV+ CPU/Memory board
configurations.
The system needs to be powered off for the EMI gasket kit installation portion of this
upgrade. Arrange with the system administrator for a scheduled system shutdown.
This upgrade procedure involves installing:
■An EMI gasket kit (if one is not already installed)
An EMI gasket kit must be installed to ensure Class A EMI compliance
worldwide. This kit must be installed while the system is powered off, prior to
the insertion of UltraSPARC IV/IV+ CPU/Memory boards.
■Power supplies of higher current ratings
■Fan trays of higher cooling capacity (Sun Fire E4900 and Sun Fire 4800 systems
only)
Note – Install the UltraSPARC IV/IV+ CPU/Memory boards only after you have
installed the other upgrade hardware.
Portions of this upgrade procedure (power supplies and/or fan trays) can be
installed in a powered-on system. However, the EMI Gasket kit must have been
previously installed.
