CHAPTER 5 PRIMEPOWER400 Rackmount (4U) Server
5.3.6 Installing the Enhanced Support Facility package
CAUTION
Data Destruction
Install the "Enhanced Support Facility" before using the system. Without this
package, a front panel-miss operation or hardware error may cause the system
to shutdown or data to be lost.
With the PRIMEPOWER servers, be sure to install all of the programs provided with the "Enhanced Support
Facility" to ensure the high reliability functions or the service processor. For details, refer to the "User’s Guide"
included with the "Enhanced Support Facility."
5.3.7 How to enable/disable the break signal
CAUTION
Data Destruction
If improper commands are used at the ok prompt, data may be lost. If you need
to use any command except those shown in this manual, you should fully
understand the function and usage of the command before using it.
Data is sometimes lost as the bootup sequence shifts to display of the ok prompt during system operation in
response to a break signal from the console terminal connected to the serial port or the STOP+A command from
the keyboard.
To prevent this kind response to a break signal arriving from the serial port or the STOP+A command from the
keyboard, make the following settings using the set-fw-options command shown below with the ok prompt
displayed on screen, and then set the MODE switch on the control panel to the SECURE mode.
How to disable the break signal and STOP A command
