This appendix contains information about the locations and behaviors of the status and fault LEDs on the server. The information is organized to describe external LEDs that can be viewed on the outside of the server and internal LEDs that can be viewed only with the component covers, including hard disk drive cover, system controller cover, and fan cover removed.
This appendix includes the following:
External Status Indicator LEDs

Internal Status Indicator LEDs
The Sun Fire X4500 server has internal status board LEDs for the CPU board, the CPU and DIMM slots on the CPU board. See the following figures and tables for information about the LEDs that are viewable on the outside of the server.
The system includes internal LEDs on the disk drives, the fan trays, and the PCI slots.
TABLE 6-3 lists the internal LEDs:

FIGURE 6-5 Disk Drive and Fan Tray LEDs
CPU Board LEDs
The CPU board has three types of LEDs. They are listed in TABLE 6-3 and appear in FIGURE 6-6.
The CPU LEDs are active only when the Remind button is depressed. They blink to indicate a failure; otherwise they stay Off.
| Note - The CPU and DIMM LEDs continue to indicate a failure until the system is powered on. The Battery LED continues to indicate a failure until the service processor is started.
