The system management card is at the left front of the case. At its center is a DB-9 serial RS-232 port which allows 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 farthest to the left indicate fault, unit ready, Host Interface cards A and B installation status, and the power status for each power supply.

Blower assemblies

To the right of the system management card are individual disk drive sleds which also have LED indicators 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 filled with empty sleds to promote effective cooling. Access is provided by loosening two screws and pulling on the sled handle.

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

The power supplies for the Diamond-VT 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 which allows you to set the SCSI ID of the Diamond-VT. The SCSI card also has an in channel, to connect by a 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.
