Turning off the power

This section explains how to turn off the power.
Data destruction
Before turning off the power, check the following to prevent the destruction of data:
l When some programs are being executed, quit them.
l When someone is currently using the system, make them stop.
l When a data cartridge is in the drive, eject it. See Section 5.3.8, "Ejecting a data
cartridge".
l Back up any files containing critical data before turning off the power.
l Do not turn off the power to the console while the main unit power is on. While the
mode switch is set to UNLOCK or MAINTENANCE, a Break signal might interrupt the
Solaris Operating Environment and change the state of the machine to OBP (ok
prompt), which might destroy data.
l When the main unit is turned off, the message "POWER ON READY" is displayed on
the operator panel. Before responding in confirmation of this message, do not turn
off any peripheral device or UPS, do not disconnect any power cable or power
distribution box, and do not turn off power to any other main unit.
4If the main unit employs software for automatic power control and the mode
switch is set to UNLOCK or LOCK, plugging a power cable into an outlet may
automatically turn on the power. To prevent such an occurrence, set the mode
switch to MAINTENANCE before plugging the power cable into the outlet.
• Procedure
1
Set the mode switch to UNLOCK or MAINTENANCE.
2
Press the power switch on the operator panel on the main unit.
A confirmation message "POWER OFF OK?" is displayed on the status display (LCD).
