    The 2104 Model DU3 is a rack-mounted SCSI disk enclosure that can be attached to server ™ ™ any RS/6000 or IBM pSeries computer that provides support for any of the Small Computer System Interface (SCSI) adapters listed in “SCSI Adapters and Cables” on page 25.
  • Page 11 On the back of the backplane are connectors for two fan-and-power-supply assemblies 3 , two SCSI interface cards 4 , and a switch card 5 . The 2104 Model DU3 has either two fan-and-power-supply assemblies or one fan-and-power-supply assembly and one fan assembly. Either option provides all the necessary power and cooling for the 2104 Model DU3.
  • Page 12: 2104 Model Tu3

    The 2104 Model TU3 is a deskside SCSI disk enclosure that can be attached to any server RS/6000 or IBM pSeries computer that provides support for any of the Small Computer System Interface (SCSI) adapters listed in “SCSI Adapters and Cables” on page 25.
  • Page 13 The 2104 Model TU3 can have either two fan-and-power-supply assemblies or one fan-and-power-supply assembly and one fan assembly. Either option provides all the necessary power and cooling for the 2104 Model TU3. The SCSI interface cards are used to connect host machines to the 2104 Model TU3. These cards contain logic that provides information about what is happening in the 2104 Model TU3, and controls the operation of the subsystem.

  • Page 15: Scsi Interface Cards

    SCSI Interface Cards Attached to the back of the backplane in a fully configured 2104 Model DU3 or 2104 Model TU3 are two SCSI interface cards. Both cards can be used to connect host machines to the 2104 disk enclosure. A SCSI interface card provides the following functions: v Supports SCSI Enclosure Services at the SCSI node at address 15 on the external SCSI bus...
  • Page 16: Fan-And-Power-Supply Assemblies

    Fan-and-Power-Supply Assemblies Attached to the back of the backplane in a fully configured 2104 Model DU3 or 2104 Model TU3 are two fan-and-power-supply assemblies. Each fan-and-power-supply assembly provides enough power for the 2104, so it is possible for there to be just one fan-and-power-supply assembly in a 2104. The second fan-and-power-supply assembly is replaced by a fan assembly.
  • Page 17: Switch Card

    Switch Card Attached to the back of the backplane in a fully configured 2104 Model DU3 or 2104 Model TU3, the switch card contains switches that control some of the functions of the 2104. Switches that are accessible from the back of the 2104 are provided to indicate: v Whether power to the 2104 is turned on or off automatically when the host computer is switched on or off v Whether the disk drive modules are started automatically when power to the 2104 is...
  • Page 18: Scsi Bus Bridge Card

    SCSI Bus Bridge Card Located centrally in the front of a 2104 Model DU3 or 2104 Model TU3, the SCSI bus bridge card controls the SCSI bus configuration of the 2104. It assigns the disk drive modules to a SCSI bus, in accordance with the setting of the SCSI bus split switch on the switch card.

  • Page 22: Environment

    Environment Temperature and Humidity A 2104 has the following environmental limits: Air Temperature Relative Humidity Maximum Wet Bulb Operating 10°C to 40°C 8% to 80% 27°C (80°F) (50°F to 104°F) noncondensing Recommended 22°C operating point (72°F) Recommended 20°C to 25°C 40% to 50% operating range (68°F to 77°F)
  • Page 23: Heat Output, Airflow, And Cooling

    Heat Output, Airflow, and Cooling The maximum heat output of either model is 330 watts (1126 BTU/hr). Each 2104 requires an airflow of 1.1 m³ ( 40 cubic feet) per minute. When racks containing many 2104s are to be installed together, the following requirements must be met to ensure that the 2104s are adequately cooled: v The airflow is in at the front of the rack and out at the back.
  • Page 24: Electrical Power

    Electrical Power Electrical power is supplied to each 2104 by either one or two fan-and-power-supply assemblies. These fan-and-power-supply assemblies convert the input voltage to dc for distribution within the 2104. One fan-and-power-supply assembly provides enough power for a fully populated 2104. If two fan-and-power-supply assemblies are present in the 2104, each disk drive module receives power from both fan-and-power-supply assemblies.

    Description Operating (100 disk ops per Two power supplies (100 second) disk ops per second) 100 VAC input 410 W 210 W each 240 VAC input 430 W 220 W each Power Factor Power factor correction is applied within the fan-and-power-supply assemblies of each 2104.
  • Page 26: Power Control

    Power Control Each fan-and-power-supply assembly in the 2104 has a DC On/Standby switch. The power to the 2104 is also controlled by the Power Control switch on the switch card. Power Sequencing The power sequencing of the disk drive modules in a 2104 is controlled by the settings of the Drive Auto-Start and Select Enclosure Services switches on the switch card.
