TABLE 2-5 Switches (Operator Panel)
Name Description of Function
Mode switch Used to set an operation mode for the server
.
Insert the special key that is under the
customer’s control, to switch between modes.
Locked Normal operation mode.
The system can be powered on with the power switch, but it
cannot be powered off with the power switch.
The key can be pulled out at this key position.
Service Mode for maintenance.
The system can only be powered on and off with the power
switch.
The key cannot be pulled out at this key position.
Maintenance is performed in Service mode while the server
is stopped.
Because remote power control and automatic power control
of the server are disabled in Service mode, unintentional
power on can be prevented.
Power switch Used to control the server power. Power on and power off are controlled by pressing this
switch in different patterns, as described below.
Holding down for a short time
(less than 4 seconds) Regardless of the mode switch state, the server (all domains)
is powered on.
At this time, processing for waiting for facility (air
conditioners) power on and warm-up completion is skipped.
Holding down for a long time
in Service mode
(4 seconds or longer) If power to the server is on (at least one domain is
operating), shutdown processing is executed for all domains
before the system is powered off.
If the system is being powered on, the power-on processing
is cancelled, and the system is powered off.
If the system is being powered off, the operation of the
Power switch is ignored, and the power-off processing is
continued.
