    If you remove an item, reinstall it into the same module slot from which it was removed—after moving the enclosure. The Model 106 ships with CRUs installed; however, the disks must be installed as part of the system setup, after the enclosure is securely mounted in the rack.
  • Page 22: Relocating Ess Racked System 5147-106 (4U106)

    CAUTION: Use a suitable mechanical lift for hoisting the enclosure for installation into the rack: • Fully configured Model 106 enclosures can weigh up to 145.6 kg (321 lb). Do not install disks until after the enclosure is secured into the rack.
  • Page 23: Operation

    – Model 106 enclosures are intended to operate with two PSUs and four system fans accessed from the rear panel. Two controller channel fan modules accessed from the top of the enclosure provide additional cooling.
  • Page 24: Product Power Rating

    • Before installing a Model 106 enclosure into the rack, see the CAUTION on page 10 and the WARNING on page 34. • The rack construction must be capable of supporting the total weight of the installed enclosures. The design should incorporate stabilizing features suitable to prevent the rack from tipping or being pushed over during installation or in normal use.
