2.3.1 Operation Panel LEDs


2.3.1 Operation Panel LEDs
The three LEDs on the operation panel indicate the operation status of the entire system. In addition, the LEDs enable you to check the system status by their combination of being on, blinking, or off. For the locations of the LEDs, see Figure 2-7.
Table 2-7 lists the system operation status indicated by the LEDs, while Table 2-8 lists the system status indicated by the combination of LEDs.
Table 2-7  System Operation Status Indicated by LEDs
Icon Name Color Description
power POWER Green Indicates the startup or stop status of the system for each chassis.
● On: System is started.

● Blinking: System stop processing is in progress.

● Off: System is stopped.
xscf standby XSCF
STANDBY		 Green Indicates the status of the XSCF for the entire system or for each chassis.
● On: The XSCF is functioning normally.

● Blinking: The XSCF is being initialized.

● Off: The XSCF is stopped.
check CHECK Amber Indicates the system operation status for each chassis.
● On: An error has been detected in hardware.

● Blinking: Chassis specified at execution of the XSCF command instructing the blinking. This (locator) is used to identify the location of the chassis requiring maintenance.

● Off: Normal, or the power is disconnected or not being supplied.

LED State Description
POWER XSCF
STANDBY		 CHECK
power xscf standby check
Off Off Off Power is disconnected.
Off Off On The XSCF detected an error before the system has started or after the system stopped.
Off Blinking Off The XSCF is being initialized.
Off On Off The XSCF is in the standby state.
The system is waiting for power-on of the air conditioning facilities (in the data center).
On On Off Warm-up standby processing is in progress. After the end of this processing, the system starts up.
System startup processing is in progress.
The system is operating.
