10.0 Hardware Maintenance

The disk drive sleds, blower assemblies, power supplies, host interface cards, and system management card may be replaced with identical or upgraded parts.

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

The only way to completely de-energize the unit is to turn off both power supplies and unplug both power cords from the back of

Exhibit 10-1: The management card may be accessed via a serial port DB-9 connector or an optional Ethernet connection.

On Stand-by

the unit. Turning the

power switch to the Stand-by position on one power supply does not completely turn off power to the Diamond-VT; it is not an AC on-off switch. Power may still be in the unit through the other power supply.

CAUTION

All modular components must be replaced by qualified personnel only. Use a static wriststrap when handling any of the cards inside the Diamond-VT. Components are electrostatic sensitive. Use proper grounding methods when working with or around the Diamond-VT. Always store spare components in proper ESD containers when not in use.

•The power supply and blower assembly may be replaced while the unit is running. (See Hot Swap Operating Instructions on page 69)

•Host interface cards and management cards may only be replaced when the Diamond-VT is off. Backup the unit fully before replacing these components.

•You may remove a disk drive sled while the Diamond-VT is powered on. See the instructions

in Hot Swap Operating Instructions on page 69 for

details.

Management card: To remove a management card, power down both power supplies, loosen the screws holding the card in place, pull out the

67

assembly and replace it with another. Securely tighten all screws after replacing the component.

To remove a disk drive sled (Exhibit 10-2), loosen the screws on either side of the assembly, then pull on the assembly’s handle and carefully slide it out of its bay.

To remove a

Fibre Channel or SCSI Host Interface Card from the back of the Diamond-VT (Exhibit 10-3), power down both power supplies and remove any cable attached to the port. Loosen the retaining screws and pull the Host Interface Card out of the unit. To replace the card, push it back into the unit and tighten the retaining screws.

To remove the power supply (Exhibit 10-4), press the Stand-by power switch to the off position, remove the power cord, and, using a No. 1 Phillips screwdriver, loosen the screws holding the assembly in place. Pull out the assembly and replace it with another. Securely tighten all screws after replacing the component.

To remove a blower assembly (Exhibit 10-4), using a No. 1 Phillips screwdriver, loosen the screws holding the assembly in place. Pull out the assembly and replace it with another. Securely tighten all screws after replacing the component.
