A P P E N D I X A

Server Status Indicators

The server has LED indicators associated with the server itself and with various components. The server status indicators are located on the bezel and repeated on the back panel. The components with LED indicators to convey status are the dry contact alarm card, power supply units, Ethernet port, and hard drives.

This appendix contains these sections:

Front Panel Indicators

Rear Panel Indicators

Note - For additional information about these indicators, refer to the Netra 240 Server Service Manual (817-2699).

Front Panel Indicators

FIGURE A-1 shows the location of the front panel indicators, and TABLE A-1 provides information about the server status indicators. For information about the dry contact alarm card indicators, refer to the Netra 240 Server Service Manual (817-2699).

FIGURE A-1 Location of the Front Indicators

Figure showing the location of the server status and dry contact alarm indicators on the bezel.

TABLE A-1 Server Status Indicators (Front and Rear)
Indicator	LED Color	LED State	Meaning
Activity	Green	On	The server is powered up and running the Solaris operating system.
		Off	Either power is not present or the Solaris software is not running.
Service Required	Yellow	On	The server has detected a problem and requires the attention of service personnel.
		Off	The server has no detected faults.
Locator	White	On	A continuous light turns on and identifies the server from others in a rack, when the ALOM `setlocator`command is used.

Hard Drive Indicators

The hard drive indicators can be seen when you lower the front bezel. FIGURE A-2 shows the location of the indicators, and TABLE A-2 provides information about these indicators.

FIGURE A-2 Hard Drive Indicators

Indicator	LED Color	LED State	Component Status
Activity	Green	Flashing	Active SCSI transactions.
Activity		Off	No activity.
Unused			Reserved for later use.
Ready to remove	Blue	On	Ready to remove.
		Off	Not ready to remove.

Rear Panel Indicators

FIGURE A-3 shows the location of the power supply unit and rear server status indicators, and TABLE A-3 provides information about the power supply unit indicators. See TABLE A-1 for information about the server status indicators.

Note - FIGURE A-3 displays a DC-powered server. The rear panel indicators can be found in the same locations on an AC-powered server.
