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.
