Troubleshooting Tools

There are a number of tools available for troubleshooting HP Integrity rx3600 servers, including LEDs, online and offline diagnostics, and system fault management tools.

LEDs

The HP Integrity rx3600 server provides front panel LED, diagnostic panel LED, and FRU health LEDs, which allow you to monitor system health.

Front Panel

The front panel of the HP Integrity rx3600 server contains the power button/System Power LED, Internal Health LED, External Health LED, System Health LED, UID Button/LED, and an INIT button. The server uses flashing states (for example, flashing amber or red) on these LEDs to indicate a warning or an error. See Figure 5-1for a detailed layout of these front panel indicators and buttons.

When you power on the server, the LEDs light up as follows:

1.Power LED turns green when the system starts to power up

2.External health indicator turns green when the BMC powers on

3.Internal health indicator turns green when the BOOT_START event is received from system firmware

NOTE: BOOT_START can be determined by LED states on the I/O backplane board.

4.The system health indicator turns green when the firmware leaves exit boot services and the server starts to boot an OS.
