Cooling Subsystem, Power Supply Power LED

NOTE: For high availability and safety reasons, the power LED is run directly from the power rails, not under firmware control.

Power Supply Power LED

There are 1 Hz flashing green POWER LED (PWR) located on each power supply, which indicate that ac power is applied to the power supply, and that housekeeping voltages are available in the server. These LEDs light steady green when power is available from the power supplies to the server. If a power supply LED flashes amber at 1 Hz, the power supply has failed.

Table 5-20lists the power supply LED states:

Table 5-20 Power Supply LED States

Power Supply Power LED	Power Supply Condition
Off	No ac power applied to any power supply
Off	No ac power applied to a specific power supply
Flashing green ~ 1 Hz	ac standby power is present
Steady green	Power supply dc outputs are functioning correctly
Flashing amber ~ 1 Hz	Power supply has failed. (includes overvoltage, overcurrent, overtemperature,
	and fan failure)

I/O VRM

Table 5-21lists the I/O power events that light the diagnostic panel LEDs.

Cooling Subsystem

The three fan cooling zones located in the rx3600 chassis provide N+1 redundancy for the chassis using three identical dual fan assembly CRUs. In turn, each dual fan assembly FRU provides additional N+1 redundancy for the fan cooling zone it cools. The fan assembly CRUs are identified in the chassis as fans 1, 2, and 3 both for logging and for fault identification on the diagnostic LED panel.

Cooling Subsystem Behavior

The BMC chip located on the core I/O board FRU controls fan speed based on ambient air temperatures, chip temperatures, server configuration, and fan operation or failure. Air is drawn through the front of the chassis and pushed out the rear by the cooling fans.

NOTE: You can display fan status remotely using the iLO 2 MP ps command.

Within HP Integrity rx3600 servers, temperature sensors report chassis temperatures to the BMC, which controls fan speed based on this information.

Table 5-22lists the cooling subsystem events that light the diagnostic panel LEDs.
