4.2	Status-indicating LEDs
4.2.1	Brief Overview of the LEDs
	The following devices all come with LEDs that inform subsystem managers about the opera-
	tional status of the component on which they are mounted. The RAID subsystem has status-
	indicating LEDs distributed over the active components in the following ways:
	Component	LEDs per Unit	Total LEDs	Definition
	Drive Trays	2	24	See Section 4.2.2 Drive Tray LEDs
	Controller	9	9	See Section 4.2.3 Controller Module
	Module			LEDs
	Ethernet Ports	2	4 (2 ports)	See Section 4.2.4 Ethernet Port LEDs
	BBU Module	1	1	See Section 4.2.5 BBU Module LED
	(if BBU is
	installed)
	PSU Module	1	2	See Section 4.2.6 PSU LEDs

4.2.2	Drive Tray LEDs

Two (2) LED indicators are located on the right side of each drive tray. (See Figure 4.1) Refer to Table 4.2 for the LED definitions. When notified by a drive failure message, you should check the drive tray indicators to find the correct location of the failed drive. Replacing the wrong drive can fail two members of a logical array and thus render the array data unrecover- able.
