2.3 Understanding the OPNL Functions
This section describes the functions of the OPNL mounted on the SPARC M12-2/M12-2S.
The OPNL is mounted at the lower right as seen from the front of the panel (see Figure 2-1).
The OPNL provides the display and control functions of the system. The field engineer and system administrator can control the operation mode or start/stop of the system while checking the LEDs indicating the system operation status.
Note - In a building block configuration, the functions of the Mode switch and POWER switch are disabled on the OPNL except for the master XSCF.
Note - In a building block configuration where the crossbar boxes are connected, all the OPNL functions are enabled only for the OPNL of the crossbar box used as the master XSCF.

Functional Overview
POWER LED Indicates the run/stop status of the SPARC M12-2/M12-2S.
XSCF STANDBY LED Indicates the XSCF status of the system.
CHECK LED Indicates any abnormality of the SPARC M12-2/M12-2S.
BB-ID switch (*1) Sets the identifier of the SPARC M12-2S.
Mode switch (*2)(*3) Sets the system operation mode.
Power switch (*2) Starts/Stops the system.
*1 The SPARC M12-2 has no BB-ID switch. The BB-ID is fixed to 0.
*2 In the building block configuration, this switch can be operated only with the SPARC M12-2S of the master XSCF.
*3 Set the same operation mode for both the SPARC M12-2S of the master XSCF and that of the standby XSCF. If the operation mode is different, an asterisk (*) is displayed next to the unit names in the output result of the showhardconf or showstatus command.
