1 Introduction Welcome Congratulations on the purchase of your new ST8000 Disk Expansion Unit (DEU). The DEU provides a superior fault-tolerant network storage solution in a subsystem-based SAF-TE compliant RAID enclosure. The SAF-TE compliant interface provides a standard, non-proprietary means for the RAID subsystem to automatically integrate with peripheral packaging that supports status signals, hot swapping drives and enclosure monitoring. Combined with the enterprise- wide RAID management

Storage Management Solution — Enterprise- wide managing and monitoring software. Where to Find Answers When you have questions about your DEU there are several places you can look to find answers. Refer to the following: In this guide: This user’s guide provides detailed information for installing and using the DEU disk array subsystem. The manual assumes that the reader is already familiar with the operating system environments where the DEU will be installed. ServerCare™ Service Support

Front Panel Components The DEU front panel comprises seven major components: Operator Control Panel, Power-On Indicator LED, Status Indicator LEDs, Alarm Speaker, Door Lock, Status LEDs, and Activity LEDs. Operator Control Panel (OCP) Speaker Status Indicator LEDs Channel Mode LED Door Lock Power Supply LED Fan Status LED Power-On LED Status Indicator LEDs Note: LEDs normally visible only when illuminated, shown here for identification.

The OCP provides a four line by twenty character display. There are five function keys for a menu driven interface. An animated icon will appear on a static display and provides an “at-a-glance” look at system status. When a “happy” animated face appears, all systems are indicating a nominal state. When the animated face changes to a “sad” face, the system indicates that a problem has been detected and requests your attention. The “power system” status will display the total power available per

Channel Mode The Channel Mode LED indicates the status of the array subsystem by changes in its color and state. When illuminated steady green, the LED indicates normal array activities. When the LED changes to amber (flashing or steady) it indicates abnormal activities, for more information see LED Descriptions described later in this guide. Power Supply Status The Power Supply Status LED indicates the condition of the power supplies by changes in its color. The LED will illuminate steady green

Door Lock The front door has an integral lock that also serves as a door handle. In addition, the door lock provides security to deter unauthorized access to the internal components. Two keys are provided with the system. To unlock the door, insert the key and turn it in a counterclockwise direction. To lock the door, turn the key in a clockwise direction. Status LEDs There are eight Status LEDs located in the windows on the front panel (for the rack-mount system they are the lower set of LEDs a

Rear Panel Components The DEU rear panel comprises four major components: I/O Interface cards, power cord connector module, fuse, and access doors to power supplies and fans. VHD SCSI Connector I/O Interface Card Power Supply #3 with PSU Cover Plate PSU “DC Good” LED Fuse AC Power Cord Connector Rear Door Fastener AC Power Cord Retainer Rear Door Panel I/O Interface Card VHD SCSI Card Handle Connector I/O Interface Card The I/O Interface card makes up the connection from the subsystem’s bus

The I/O Interface card incorporates built-in automatic SCSI termination. When the data cable is plugged in, the system automatically senses the connection and provides the required SCSI termination. Two sets of jumpers are provided on the card. One set routes Term Power in the event that the host controller is not providing it. The next set of jumpers addresses a specific set of controllers that use the DEC Fault Bus protocol. If you are using a DEC system where the controller uses this protocol

The drive mounting design incorporates a rail system with built-in connectors making it possible to “hot swap” a drive without shutting down the system. This design allows for easy installation with minimal force and latching clips to secure the drives into place. Note: All drives in an array should be of the same capacity. If the drives are mixed, all of the drives in the array are assigned the capacity of the smallest size drive. Power Switch The power switch is located inside the locking fron

Located in the tower-based systems’ top bay or the rack-mount systems’ far left bay are two card slots. The Ultra S2S RAID Controller (optional) and the SAF-TE card are installed in these two slots. The Ultra S2S RAID Controller will be installed in the upper most (or furthest left) slot. The SAF-TE card is installed in the next slot down or to the right. Hot Swappable Cooling Fans The cooling system consists of two high-performance fans fitted to the rear panel. These fans draw air from a high

If a failure occurs, the Power Supply Status LED will illuminate amber and the audible alarm will sound. The user can identify the failed component by accessing the OCP and viewing the “Hardware Status.” The PSU “DC Good” LED will not be illuminated on the failed power supply, see Replacing a Power Supply described later in this guide.
