Before You Begin; What To Do - Sun Microsystems Fire V890 Service Manual

Note – Use only Sun Fire V890 200-240 VAC power supplies in the Sun Fire V890
system.

Before You Begin

It is not necessary to power off the system if you are removing a redundant power
supply. For more information about power supplies, see:
"About Power Supplies" on page 231
■
"About Hot-Pluggable and Hot-Swappable Components" on page 6
■
Note – Unlike hot-pluggable devices, you can install or remove a power supply or
fan tray while the system is operating at the ok prompt. However, in the case of the
power supply, you must issue a reset-all command at the ok prompt in order for
the system to recognize the change the next time the operating system is booted.
If you are not performing a hot-plug procedure, complete this task:
"How to Power On the System" on page 2
