Power Supplies

CAUTION

Do not leave empty openings on the front or rear of the Diamond-VT under any circumstances. Empty openings affect airflow and may cause the unit to overheat and shut down.

WARNING

Hazardous voltage and stored energy hazard when removing power supplies.

In a system with at least one operational power supply, the other power supply can be successfully removed and replaced without powering the system down and with no loss of array functionality. The green activity LED on the front of the system management card identifies the operational status of each power supply (Green means the power supply is operating correctly).

Note

System command overlap is discontinued across some drives when only one power supply is operational.

Labels on the rear of the Diamond-VT point to the appropriately related A and B power supplies.

1Identify the power supply to be swapped on the rear of the unit.

2Turn off the power supply on/off switch.

3Disconnect AC line cord.

4Unscrew the two screws on the power supply with the appropriate tool.

5Pull power supply out of chassis using the power supply module handle.

6Install new power supply in chassis with proper orientation (Power supply is keyed and can only be inserted one way).

7Tighten the two screws on the power supply with the appropriate tool.

8Connect AC line cord

9Turn on power supply switch.

10Verify correct operation by observing that the green light on the rear of the power supply is lit and that the appropriate power

supply light on the system management card on the front of the unit is lit.

Note

It takes up to 30 seconds for the system to recognize the insertion or

removal of a power supply and change the LED on the system management board. The CLI will issue messages about the change (see Diagnostics, Upgrade and Maintenance on page 57).

Blower Assemblies

CAUTION

Do not leave empty openings on the front or rear of the Diamond-VT under any circumstances. Empty openings affect airflow and may cause the unit to overheat and shut down.

The Diamond-VT contains two blower assemblies. The blowers are critical to proper array cooling operation. However, the array can operate with only one functional blower within certain ambient temperatures. The blowers are electronically connected to the power supplies and a power supply will not run without its corresponding blower assembly operating. This means if the blower adjacent to power supply A is removed, the ‘A’ power supply will shut down, turning off the corresponding LED on the system management card. The CLI will issue a message about the power supply being turned off.

To replace a blower assembly

1Unscrew the two screws on the blower assembly with the appropriate tool.

2Pull the blower assembly out of chassis.

3Install new blower assembly in chassis with proper orientation (Blower assembly is keyed and can only be inserted one way).

4Tighten the two screws on the blower assembly with the appropriate tool.

5Verify correct operation by observing that the green light is lit on the rear of the power supply, and that the appropriate power supply green light on the system management card on the front of the unit is also on.

Note

It takes up to 30 seconds for the system to recognize the insertion or removal of a power supply and change the LED on the system
