Installing enclosures

Following your enclosure location plan, install the control enclosure.

About this task

The installation procedure applies equally to control enclosures and expansion enclosures.
  • Lifting a control enclosure requires at least three people.
  • Lifting an expansion enclosure requires at least two people.
  • Each control enclosure must be installed only on the control enclosure rails provided with the enclosure.
  • Each expansion enclosure must be installed only on the expansion enclosure rails provided with the enclosure.
CAUTION:
  • To lift a control enclosure requires at least three people.
  • Install a control enclosure only onto the control enclosure rails supplied with the enclosure.
  • Load the rack from the bottom up to ensure rack stability. Empty the rack from the top down.

Procedure

To install an enclosure, complete the following steps.

  1. On either side of the drive assemblies, remove the enclosure end caps by grasping the handle and pulling the bottom of the end cap free, then clearing the tab on the top of the enclosure.
    (See Figure 1.)

  2. Align the enclosure with the front of the rack cabinet.
  3. Slide the enclosure into the rack along the rails until the enclosure is fully inserted. (See Figure 2.)
    Note: The rails are not designed to hold an enclosure that is partially inserted. The enclosure must always be in a fully inserted position. Control enclosures must be installed only on the supplied control enclosure rails. Do not install a control enclosure on expansion enclosure rails.

  4. Secure the enclosure with screws in the rack mounting screw holes on each side of the enclosure.
    (See Figure 2.)

    Some enclosures are secured by one silver captive screw and one black M5 screw on each flange. In this case, align the enclosure, fasten the two captive screws, and then fasten the two M5 screws. See Figure 3

  5. Reinstall the left and right end caps.
    (See Figure 4.) The left end cap has indicator windows that align with the status LEDs (light-emitting diodes) on the edge of the enclosure.
    1. Ensure that the serial number on the left end cap matches the serial number on the left flange ("ear") on the front of the enclosure.
    2. Fit the slot on the top of the end cap over the tab on the flange.
    3. Rotate the end cap down until it snaps into place.
    4. Ensure that the inside surface of the end cap is flush with the flange.

What to do next

If you removed components from the enclosure to lift it, reinstall the components into the slots of the enclosure from which they were removed.
