2.4.3 LEDs on each component


2.4.3 LEDs on each component
Each component of the SPARC M10-4/M10-4S has a mounted LED. If a component experiences an error, check the LEDs to see which component requires maintenance. Check the LEDs before starting maintenance work.

The LEDs on each component and the states that they indicate are as follows.

Table 2-12  XSCF LEDs and their states
Name Color State Description
READY Green On The XSCF is running.
Blinking The XSCF is being started.
Off The XSCF is stopped. Alternatively, it has been disconnected from the building block configuration.
CHECK Amber On Indicates that an error has occurred.
Normal if the LED is turned off after it is on for a few seconds when the power is turned on
Off Indicates the normal state.
MASTER
(SPARC M10-4S only)
Green On Master chassis
Off The XSCF is in the state of being started. Alternatively, the XSCF is in the standby state or operating as a slave XSCF.

Name Color State Description
CHECK Green On Indicates that the input power is turned on and being supplied normally.
powercheck Blinking Indicates that the input power is being disconnected.
Amber On Indicates that an error has occurred.
Indicates that the input power to this power supply unit is turned off in redundant operation.
Blinking Indicates the warning status (an error has occurred but the power supply unit is operating).
  Off Indicates that power is not being supplied.

Name Color State Description
READY Green Blinking Indicates that the disk is being accessed. This LED is normally on, but it blinks while the disk is being accessed.
While the LED is blinking, maintenance such as removal of the disk cannot be performed.
Off Indicates that maintenance such as removal of the disk can be performed.
CHECK Amber On Indicates that an error has occurred.
Blinking Indicates that the component requires maintenance.
(This function is also referred to as the locator.)
Off Indicates the normal state.
