RS-232 interface for monitoring and configuration via a terminal. Power Supplies The VOYAGER 3000 uses two high performance power supply units per backplane. A single power supply is rated at 180 Watts. Each power supply is rated at greater than 500,000 hours MTBF with a second power supply providing full redundancy capabilities. -
Page 19: Raid Basics
The industry standard SCA2 connector is used to interface between the device and the backplane. SCA features staggered contact pins and insertion guidance. All signals such as SCSI, Ids, Power etc. are carried through the SCA. This lowers cost, enhances reliability and fully conforms to the Ultra SCSI specification. -
Page 20: Raid 3
Voyager 3000 User Guide RAID 3 Block Striping with Dedicated Parity - Data is broken into logical blocks, the size of a SCSI disk block, and striped across several drives. One drive is dedicated to parity. In the event of failure, original data is re-generated from the parity information. -
Page 21: Chapter Two
The maximum operating temperature of the Voyager 3000 is 40 degrees centigrade, however it is not recommended that the system is continuously run at these elevated temperatures. -
Page 22: Electrical Considerations
Care should be taken to ensure that the current does not exceed the rating of the power source circuitry. This includes cabling, power distribution units, filters and any other components through which the main A/C flows. The power requirements of the Voyager 3000 shelf is 1Amp @200Volts and 2A @100Volts and must be added to the power demands of any other electrical devices installed in the cabinet to arrive at a total power consumption figure. -

DPS1 Sw1 DPS1 Sw2 (ID Bit0) (ID Bit1) DPS1 Sw5 DPS1 Sw6 (ID Bit0) (ID Bit1) Cabling and Termination Issues SCSI requires that cable lengths be no greater than 6 metres at 5MHz clock rates and no greater than 3 metres at 10MHz clock rates when used in SCSI -2 single ended mode. -
Page 29: Components
Note Ultra SCSI has very stringent requirements regarding cable length. Any cables connected to Ultra devices must conform to Ultra SCSI specifications. When there are excess of 4 devices cable length should be no greater than 1.8 metres for single ended Ultra SCSI. The implication of this is that for any Ultra SCSI system the initiator and target will try to transfer data at Ultra SCSI rates during the initialisation process regardless of the number of devices and cable length. -

Drive Removal Prior to complete removal of the carrier from the VOYAGER 3000 system you must ensure that the drive has fully spun down as centrifugal forces may damage the device. You must ensure that adequate shock and anti-static precautions are complied with. -
Page 34: Psu Insertion And Removal
Voyager 3000 User Guide PSU Insertion and Removal The VOYAGER 3000’s power supply is designed for hot pluggable operation. To achieve this temperature sensitive current limiting is used. As the temperature to the devices increase the current limiting function decreases. This will prevent undesirable surges. If removing and replacing the same PSU please ensure that at least one minute has elapsed between removal and re-insertion which will allow components to cool to ambient temperature. -
