  • Page 16: Introduction

    EMC produces two types of DAE2. The standard version includes high-performance Fibre Channel disk drives and FC-AL link control cards to manage them. The DAE2-ATA (Advanced Technology Attachment) version uses economical, high-capacity ATA disk drives and FC-to-ATA link control cards to manage the disks and provide an interface between the FC-AL and the drives.

  • Page 17

    About DAE2 Disk Enclosures Any DAE2 can support up to fifteen 3.5-inch disk modules. Simple serial cabling provides easy scalability. You can interconnect DAE2s to Fibre Channel loops (sometimes called busses) to form a large disk storage system; the number and size of loops depends on the capabilities of your storage processor.

  • Page 18: Dae2 Front Led Display

    About DAE2 Disk Enclosures provides slots for two identical components, the components are called component-name A or component-name B, as shown in the illustrations. For increased clarity, the following figures depict the disk enclosure outside of the rack cabinet. Your disk enclosure may be installed in a rackmount cabinet as shown in Figure 1-1.

  • Page 22: Disk Modules

    About DAE2 Disk Enclosures A latch on the LCC locks it into place to ensure proper connection to the midplane. You can add or replace an LCC while the disk enclosure is powered up. Disk Modules Each disk module consists of one disk drive in a carrier. You can add or remove a disk module while the DAE2 is powered up, but should exercise special care when removing modules while they are in use.

  • Page 23: Power Supply/system Cooling Modules

    About DAE2 Disk Enclosures The latch holds the disk module in place to ensure proper connection with the midplane. Disk drive Activity/Fault LEDs are integrated into the carrier. Power Supply/System Cooling Modules The power supply/system cooling (power/cooling) modules are located above the LCCs. The units integrate independent power supply and dual-blower cooling assemblies into a single module.

  • Page 26: Requirements

    Installing a DAE2 Requirements This section explains site and cabling requirements. Site Requirements For proper operation, the installation site must conform to certain environmental specifications. These are detailed below and in Appendix A. Power To determine a DAE2’s worst case power requirements, use the power rating on the enclosure label.

  • Page 27: Installing A Disk Enclosure In A Cabinet

    Installing a DAE2 EMC supports and can provide 1-, 5-, and 10-meter cables. The 5- and 10-meter cables are equalized. Interconnections between disk enclosures should maintain LCC consistency; that is, one Fibre Channel (FC) loop should interconnect all and only the LCC As, and the other Fibre Channel loop should interconnect all and only LCC Bs.

  • Page 28: Setting Up An Installed Disk Enclosure

    Installing a DAE2 Das Gehäuse ist schwer und sollte nur von zwei Personen in einem Rack installiert werden. Zur Vermeidung von körperlichen Verletzungen und/oder der Beschädigung des Gerätes, bitte das Gehäuse nicht ohne die Hilfe einer zweiten Person anheben und einbauen.

  • Page 29: Setting The Enclosure Address (ea)

    Installing a DAE2 CAUTION Each drive reads its FC-AL physical address only at powerup or when the drive is reset. To avoid losing data, you must set the enclosure address when power is off; you cannot change the EA while power is on. 1.
