Sun Microsystems CP3260 manual LEDs, Power Control, System Monitor ADM1026 and Thresholds

5.2.8.5LEDs

The Netra CP3260 blade server supports three LEDs compliant with ATCA specification:

■Green LED – Healthy status

■Amber LED – Fault condition

■Blue LED – Indicates that blade server is safe for removal when on and hot swapping in progress when blinking.

The LEDs are controlled by H8.

5.2.8.6Power Control

The BMR-H8S is able to control (enable/disable) power rails to the payload.

5.2.8.7System Monitor (ADM1026) and Thresholds

The Analog Devices ADM1026 is used for system monitoring functions. The ADM1026 is interfaced with the IPMC, and the IPMC firmware is responsible for monitoring these sensors.

Voltage Monitoring

The ADM1026 measures most of the blade server voltages. The ADM1026 has one temperature sensor embedded in the device itself and supports two remote sensing channels that require external diodes for temperature sensing. These two remote sensors are used for measuring the CPU thermal diode temperature.

The ADM1026 measures the voltages listed in TABLE 5-1. The ADM1206 and H8 firmware monitors these voltages. When the voltages are within regulations, the blade server functions with no warnings. When any voltage goes out of regulation beyond approximately ± 7%, a Critical Warning is generated and presented to the shelf manager.
