  • Page 28: Installing A Dpe2 In A Cabinet

    CX200-Series DPE2s mount inside a cabinet on two L-shaped mounting rails connected to the cabinet’s vertical channels. If you need to install a cabinet or CX200-Series chassis, refer to one of the following manuals: Installing the cabinet itself is explained in the cabinet installation manual shipped with the cabinet.

  • Page 29: Setting Up An Installed Cx200-Series Dpe2

    The EA can range from 0 through 7, though we recommend that you number them consecutively from 0. The CX200-Series DPE2 is always enclosure 0. An additional DAE2 disk enclosure is usually numbered 1, reflecting its position on the Fibre Channel loop (bus) connecting the array.
