Identifying Status and Fault LEDs
|
This appendix contains information about the external and internal LEDs on the Sun Fire Sun Fire X4500/X4540 Servers server.
This chapter includes the following topics:
Sections describe the controls and indicators on the front and rear panels of the Sun Fire X4540 server. These sections describe external status LEDs that you can see from the outside of the server.
Additional sections describe internal status and fault LEDs that can only be viewed with the hard disk drive cover, system controller cover, and fan cover removed.
The following figures and tables describe the features and status indicator LEDs that are visible outside of the server.

Internal Status Indicator LEDs
The Sun Fire X4540 server has internal status board LEDs for the CPU board, the CPU and DIMM slots on the CPU board. The system includes internal LEDs on the disk drives, the fan trays, and the PCI slots.
See the following figures and tables for information about the LEDs that you can view inside of the server.
Disk Drive and Fan Tray LEDs
FIGURE 14-4 shows the location of the disk drive and fan trays. FIGURE 14-5 shows a close-up view of the disk drive and fan trays and also shows the symbols that identify the LEDs.
FIGURE 14-4 Disk Drives and Fan Trays
FIGURE 14-5 Disk Drive and Fan Tray LEDs
CPU Board LEDs
The CPU board has three types of LEDs, DIMM fault, CPU fault, and battery fault.
The CPU LEDs are active only when the Remind button is depressed. CPU LEDs 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.
|
Internal LEDs appear in FIGURE 14-6 and are listed in TABLE 14-3.
