The MissionCritical™ ETI0014-D4 (D4 for short) is ideally suited for critical applications requiring rugged rack or table mount and/or portable construction, high reliability, compact size and light weight design. The heavy duty chassis occupies only 3U of rack space while accommodating up to four full height, shock mounted, mass storage bays each powered by redundant 65 watt power supplies. Each bay can have mounted either one full height or two half height or three slim height devices. The front panels provide access to either two full height or four half height devices with removable media (i.e. floppy disks, tape cartridges, CD-ROMs, or optional drive shuttles). The rounded metal corners and rugged handles, aid in safe handling. The chassis has threaded inserts for four of the more commonly used rack slides. The optional mounting kit includes flanges and legs for horizontal or vertical mounting other than rack. Internally, all major components are well secured and electrically insulated to prevent damage due to shock and vibration. Additionally each drive bay is shock mounted within the chassis. The universal input selects from either domestic or international voltages automatically. The LED arrays keep the operator informed as to the power and activity status of each device. Controls and protective devices are brought to the front control panel which is recessed to prevent damage or accidental operation. The input switch, fuses and wiring provide double pole isolation for shipboard systems. A bi-directional single-ended to differential SCSI converter option allows the mixing of both single-ended and differential SCSI devices on one SCSI bus. This option is available for either Fast SCSI-2 or Fast-Wide SCSI-2 and SCSI-3.

The rear panel provides four interface panel positions. Interface panel options are available for all standard SCSI connectors. These can be mixed and matched to suit a particular configuration. An optional SCSI ID selector switch panel allows external setting of device IDs. Dual washable intake air filters and high capacity ball bearing fans provide added protection in both controlled and hostile environments. The cooling air is diverted out the front vents after passing by both top and bottom of each device.

Overall, the MissionCritical™ line is uniquely qualified for critical shipboard, vehicle, airborne or land based systems combining advanced modular design features with highly reliable construction.
