1System LEDs, 2Fan Tray LEDs | Sun Microsystems V490 specification

Listed from left to right, the system LEDs operate as described in the following table.

TABLE 2-1System LEDs

Name	Description

Locator	This white LED is lit by the Sun Management Center, RSC
	software, or by the Solaris command to locate a system.
Fault	This amber LED lights when the system hardware or
	software has detected a system fault.
Power/OK	This green LED lights when the main power (48 VDC) is
	on.

The following table describes the fan tray LEDs.

TABLE 2-2Fan Tray LEDs

Name	Description

Fan Tray 0	This amber LED lights when a fault is detected in the CPU
(FT 0 Fault)	fans.
Fan Tray 1	This amber LED lights when a fault is detected in the PCI
(FT 1 Fault)	fans.

The following table describes the disk drive LEDs.

TABLE 2-3Hard Disk Drive LEDs

Name	Description

OK-to-Remove	This blue LED lights when it is safe to remove the hard disk
	drive from the system.
Fault	This amber LED lights when the system software detects a
	fault in the monitored hard disk drive. Note that the system
	Fault LED on the front panel will also be lit when this
	occurs.
Activity	This green LED lights when a disk is present in the
	monitored drive slot. This LED blinks slowly to indicate that
	the drive is spinning up or down, and quickly to indicate
	disk activity.

Further details about the diagnostic use of LEDs are discussed separately in the section, “How to Isolate Faults Using LEDs” on page 172.
