User Service Guide, Third Edition - HP Integrity cx2620 Server

NOTE: HP Integrity cx2620 front panel LEDs might not display accurate system information
if input power is removed from one or both power supplies.
However, removing input power is NOT equivalent to a power supply failure as detected by
the circuitry which drives the front panel LED status. That is, when external power is removed,
so too is the system’s ability to set the state of these LEDs. Therefore it is a normal and expected
behavior of the system that LEDs might not properly reflect power supply status when input
voltage is removed.

Attention required. Look at the diagnostic LEDs
and the MP Status log for information. The LEDs
turn off when you access the MP log.
NOTE: Input power must be maintained to both
power supplies (even those that have failed) for
LEDs to display accurate system faults.

Fault detected. Look at the four diagnostic LEDs
and the iLO MP status log for information. The
LED is turned off by the MP DC command, or by
correcting the problem.

Displays system error condition (when system
LED is flashing yellow) or fault condition (when
system LED is flashing red). For error code
