temperature warning alarm will report OK during normal operating conditions.

In an abnormal operating condition, such as blower failure, under high ambient temperatures when the Diamond internal midplane temperature reaches a critical point, the temperature alarm will report Warning and activate the audible alarm and fault LED on the front of the unit. If the internal

midplane temperature were to reach a higher point, the temperature warming alarm will report Critical, the Array will be taken off line, and all disk drive activity will be disabled. When the ambient temperature decreases to within standard operating range, the drives will be powered back on and the host will be allowed to access the data.

Exhibit 9.0-1 Typical Diamond-VT operation over a range of external ambient temperatures. Alarms will be audible, visual, CLI and SES cues as described above.

Power Supply Monitoring The Diamond-VT

monitors the operation of its power supplies and blower assemblies every 30 seconds. If the status changes, the system reports it visually with an LED and a message in the CLI.

If a power supply or blower fails, the management system sends a CLI message and turns off the corresponding power supply LED.

The blower assembly directly adjacent a power supply must be functioning properly for the power supply to work properly. If a blower assembly fails, the power supply will shut down and the management system will send a CLI message. The corresponding power supply LED on the system management card will also turn off.

If a good replacement power supply or blower assembly is inserted into the array, the management system will send a CLI message and the corresponding system management card LED will go on. It may take up to 30 seconds for the system to note these changes.

System Fault LED and Error Codes If a serious

hardware or software error occurs in the Diamond-VT, the System Fault LED will display a series of flashes or blink codes. Error information will be reported via the Command Line Interface if it is operational.

At power up, the green Diamond Array Ready (RDY) LED turns on after successful completion of the POST (Power On Self Test) indicating the array is ready for normal operation.

During operation, the Ready LED will stay lit even if the amber Fault (FLT) LED lights.

If a serious error occurs in the array, the amber Fault LED will flash repeatedly in a blink code pattern:

•an initial series of blinks indicating the system problem

•a two second pause

•another series of blinks providing more detailed information for technical personnel.

•a four-second pause

•the blink code sequence will repeat from step 1 until the error is cleared.

In general, any fault will require notification of Diamond Array technical personnel for resolution or for further debug instructions. When you report
