2.3.2 Control function of the operation panel
The operation panel has the following switches to implement its control function:
  1. BB-ID switch
    Identifies the SPARC M10-4S.
  2. Mode switch (slide switch)
    Specifies the operation or maintenance mode.
  3. Power switch
    Controls start/stop of the system.

Location number Switch
1 BB-ID switch (SPARC M10-4S only)
2 Mode switch
3 Power switch
BB-ID switch
Use the BB-ID switch to set the BB-ID number of the SPARC M10-4S. Set #0 to #15 for the SPARC M10-4S. Table 2-5 describes how to operate the BB-ID switch.
Table 2-5  How to operate the BB-ID switch
Operation Description
Pressing the + side. The BB-ID number increases by 1.
Pressing the - side The BB-ID number decreases by 1.
Mode switch (slide switch)
Use the mode switch to set the operation mode for the system. The Locked and Service operation modes can be switched by sliding the mode switch.
Note - Set the same operation mode for both the SPARC M10-4S of the master XSCF and that of the standby XSCF.
Table 2-6 describes the difference between the modes.
Table 2-6  System operation modes
Icon Operation mode Description
locked_mode Locked mode Mode used for normal operation
- The power switch can be used to start the system but not to stop it.
service_mode Service mode Mode used for maintenance
- The power switch cannot be used to start the system but can be used to stop it.

- Place the system in Service mode to perform maintenance work with the system stopped.
Power switch
Use the power switch to start or stop the system. The system starts/stops differently depending on how the power switch is pressed.
Table 2-7 describes how system starts/stops vary depending on how the power switch is pressed.
Table 2-7  Functions of the power switch
Icon Operation Description  
power switch Brief press
(For 1 second or more and less than 4 seconds)
If the system has been started in Service mode (*1): Operation is ignored.
If the system is stopped in Service mode: Operation is ignored.
If the system has been started in Locked mode (*1): Operation is ignored.
If the system is stopped in Locked mode: Starts the system.
If a wait time for the air conditioning facilities or a warm-up time is set on the XSCF, the processing for waiting for the power-on of the air conditioning facilities and the completion of warm-up is omitted.
Long press
(For 4 seconds or more)
If the system has been started in Service mode (*1): Perform the system shutdown process to stop the system.
If the system startup process is in progress in Service mode: Cancels the system startup process and stops the system.
If the system stop process is in progress in Service mode: Continues the system stop process.
If the system is stopped in Service mode: Operation is ignored.
Even a long press does not start the system.
If the system is stopped in Locked mode: Starts the system.
If a wait time for the air conditioning facilities or a warm-up time is set on the XSCF, the processing for waiting for the power-on of the air conditioning facilities and the completion of warm-up is omitted.
If the system is not stopped in Locked mode: Operation is ignored.
*1 If the system has been started, it means that at least one physical partition has been powered on.
Table 2-8 describes the functions of the mode switch.
Table 2-8  Functions of the mode switch
Function Mode switch
Locked Service
Start/stop of the system by the power switch Only system startup is enabled. A long press powers off the system.
Inhibition of break signal reception
Enabled. Using the setpparmode command, you can specify whether to receive break signals or inhibit their reception for each physical partition.
Disabled
