Data Destruction
Pressing the REQUEST switch while the system is running may
cause data to be lost.
The REQUEST switch is for outputting a memory dump when an error has occurred in the system.
Only service engineers should operate the REQUEST switch.
(4) LCD panel
The 16-digit x 2-row LCD panel displays the status of initial diagnostics performed when the power
is turned on.
It also displays error messages when a hardware error has been detected. For details on error
messages that maybe displayed, see "13 Troubleshooting".
A LCD panel error message is cleared by one of the following:
When the problem has been fixed
When the power is next turned on
When the main AC power is cut off.
Some displayed error messages may be cleared when the RESET switch is pressed.
(5) POWER switch (push button)
The POWER switch instructs the system to return the power on and off.
Power on and off of expansion units (such as the Expansion Disk Cabinet) is interlocked with the
powering on and off of the PRIMEPOWER400 Rackmount (10U) Server.
Operation of the POWER switch varies according to the MODE switch and scftool (software
contained in the "Enhanced Support Facility") settings. For details, see "(2) MODE switch" and the
"Enhanced Support Facility User’s Guide."
