3.1 Diamond-VT Components

The Diamond-VT has been designed to be easy to use, maintain and upgrade. It features a durable steel outer case and modular components in either a floor or a rack mount model.

Immediately upon receipt, check the shipping carton for damage from mishandling. Contact us at once via the means that is easiest for you (see Warranty on page A-xv)if the carton has been mishandled or displays any signs of damage.

The front of the Diamond-VT provides access to the management card and disk drive sleds. The

rear of the unit holds the host interface cards, power supplies and blower assemblies.

CAUTION

All modular components must be replaced by qualified personnel only. Refer to Hot Swap Operating Instructions on page 69.

Floor model

The management system card is at the top front of the case. At its center is a DB-9 serial RS-232 port, a connection for setup, monitoring and upgrade of the unit from any computer system with an RS-232 interface. The optional 10/100 BaseT Ethernet management services card enables Telnet-based monitoring and management. It also provides the ability to update the firmware in the array via FTP.

LEDs to the port’s right indicate fault, unit ready, host interface cards A and B installation status, and the power status for each power supply.

Below the management system card are individual disk drive sleds which also have LEDs for each drive’s status. Each sled contains two hard drives. Up to 24 hard drives may be installed on the 12 sleds. Empty bays should be covered by blank faceplates

or empty sleds. Access is provided by loosening two screws and gently pulling on the sled handle.

On the rear of the unit are blowers which support hard drive, cabinet and power supply cooling. The blowers are held in by removable screws. Correct operation is displayed by a LED at the top of each panel.

The power supplies for the Diamond-VT, also in the rear of the unit, are accessible by loosening two screws and pulling on the power supply module handle. The power standby on/off switch is at the top of each module. A yellow LED indicates caution and a green LED indicates on. The power cord socket is at the bottom of each power supply.

Between the power supplies and blower assemblies are two slots that hold the Host Interface cards. The HIC is the connection point into the Diamond-VT and is available in a 2- Gigabit Fibre Channel or Ultra 160 SCSI. Host Interface cards have fault and on-lineor fault and activity LED indicators, depending on the model. SCSI The SCSI card faceplate has a rotary binary-coded hex switch to set the SCSI ID of the Diamond-VT. The SCSI card also has an in channel, to connect via cable to the unit’s communication source, and an out channel, available for daisy-chaining arrays together or to complete termination using an external LVD terminator.
