Preparing for installation

Edit online

There are important preparation requirements and handling procedures for use during product installation.

Overview

CAUTION:

The Disk Enclosure - together will all its component parts - is too heavy to manually lift and install into the rack cabinet. A minimum of three people and a suitable mechanical lift are required to hoist the Disk Enclosure and install it into the rail kit assembly within the rack.

Make sure you wear an effective anti-static wrist or ankle strap and obey conventional ESD precautions when touching modules and components. Do not touch mid-plane, motherboard, or module connectors. See also the section, ESD precautions.

Unpacking the Disk Enclosure

Before unpacking the Disk Enclosure, familiarize yourself with the exploded view of packaging components that pertain to your enclosure product. See also Enclosure packaging.

  1. Examine the packaging for crushes, cuts, water damage, or any other evidence of mishandling during transit.

    If you suspect that damage has happened, photograph the package before opening, for possible future reference. Retain original packaging materials for use with returns.

  2. The unpacking sequence pertaining to 4U enclosures is shown in the following figures.
    CAUTION:
    The Disk Enclosure does not ship with disk drive modules installed, but all rear panel CRU modules are installed. This partially populated Disk Enclosure is quite heavy: 64 kg (142 lb).

    You can remove the Disk Enclosure from its shipping box using the standard belt-style lifting straps. If available, you can remove the enclosure from its box using the optional lift handles instead of the straps.

    • Default method: remove the Disk Enclosure from its box using the straps. See the figure below, and the CAUTION above and below the figure. The figure shows buckled belt-straps secured longitudinally on the Disk Enclosure. Only the straps and plastic bag are shown. They are isolated from the remainder of the packaging. As a visual aid for this unpacking task, see Enclosure packaging for more information about the packaging materials.
      CAUTION:
      Verify that each belt strap is securely wrapped and buckled before performing the lift.

      CAUTION:
      With three persons - positioned one at each corner rear corner, and one at the front of the enclosure - grip the straps securely by the loops, and lift the enclosure out of the box using appropriate lifting technique. Place the enclosure in a static-protected area.

      Except for the disk drive modules, enclosures are supplied with all integrated PCBs and all plug-in modules installed. For information about plug-in module replacement, see the section Module removal and installation. Disk drive modules are installed separately after the enclosure is mounted in the rack.

    • Alternative method: remove the enclosure from its box using the optional lift handles.

      See the figure below and the CAUTION above and below the illustration. Only the straps and plastic bag are shown. They are isolated from the remainder of the packaging. As a visual aid for this unpacking task, see Enclosure packaging for more information about the packaging materials. The illustration shows two steel lift handles installed on the left side of the chassis just below the enclosure lid. Two additional steel lift handles are symmetrically attached on the right side of the enclosure (hidden in this view).

      CAUTION:
      Verify that each of the four lift handles is securely fastened to the enclosure sheet metal before performing the lift. Optional lift handles are attached to the enclosure side wall using the spring-loaded push-pull attachment pin located on the attachment flange of each lift handle. These handles are designed to support the weight of a partially populated enclosure: chassis and CRUs only (as shipped). The handles are not designed to hold the weight of a fully populated enclosure that also includes the disk drives.

      CAUTION:

      With two persons - positioned one on each side of the enclosure - grip the handles securely, and lift the enclosure out of the box using appropriate lifting technique. Place the enclosure in a static-protected area.

      Except for the disk drive modules, enclosures are supplied with all integrated PCBs and all plug-in modules installed. For information about plug-in module replacement, see Module removal and installation. Disk drive modules are installed separately after the enclosure is mounted in the rack.

  3. Prepare to install and set up the enclosure.
    1. Before installing the enclosure into a rack, see Safety guidelines, and the Installing the Disk Enclosure WARNING.
    2. For rackmount installation, do not install the disk drive modules until after the enclosure is mounted in the rack.

Required tools

#2 Phillips screwdriver

Requirements for rackmount installation

You can install the enclosure in an industry standard 1.2 m cabinet capable of holding 4U form factors.
  • Minimum depth: 1,206.5 mm (47.5") from rack posts to maximum extremity of enclosure (includes rear panel cabling and cable bend radii).
  • Weight: Up to 145.6 kg (321 lb), dependent upon configuration, per Disk Enclosure.
  • The rack should cause a maximum back pressure of 5 pascals (0.5 mm water gauge).
  • Before you begin, ensure that you have adequate clearance in front of the rack for installing the rails and the CMA.
  • Follow the sequence of tasks provided in the Installation checklist
CAUTION:
  • The mechanical lift and the rack must be level in all planes, and with respect to each other. Failure to comply could result in mechanical failure of the rail kit.
  • Use a “spotter” to observe installation from the rear of the rack. The spotter should ensure the inner rail is fully mated with the middle rail track throughout installation.
