(3) REQUEST switch (push button)
CAUTION
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 turn 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 (4U) 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."
(6) CHECK LED
IMPORTANT
When the PRIMEPOWER400 Rackmount (4U) Server detects an error in the power line or
abnormal temperatures, the CHECK LED blinks and the power is automatically turned off
to prevent unit damage and ensure safety.
The CHECK LED blinks or lights up when the PRIMEPOWER400 Rackmount (4U) Server detects
an error.
When the power is turned on, the CHECK LED lights up and then goes out. This is not an error. If
the CHECK LED stays lit and does not go out at power on, this indicates an error.
When an error occurs, note down the details displayed on the LCD panel, and contact a service
engineer.
(7) POWER LED
The POWER LED indicates the power state of the system. This LED lights up when the power is
on, and goes out when the power is turned off.
Data Destruction
Pressing the REQUEST switch while the system is running may
cause data to be lost.
