Diagnostic Leds; Location Of The Leds; Interpreting The Led Indicator Values - HPE AlphaServer 300 User Manual

Diagnostic LEDs

Your system contains eight diagnostic LED indicators on the rear of the motherboard
(visible through two small holes in the rear panel). The LEDs indicate errors that occur
during system initialization and power-on self-test (POST).

Interpreting the LED Indicator Values

LED indicator values correspond to power-up tests. Table 5-5 lists these LED indicator
values and their meanings. The last two indicator values shown on the table indicate a
successful power-up. The meanings are valid when the LEDs have stopped sequencing
through tests due to an error condition. The LED Indicator Values column of the table
shows the LEDs as you view them from the rear of the system. If any LED codes other
than the last two listed in Table 5-5 are displayed, contact field service.
