Cabinet Space Planning

Context

• Equipment dimensions

  The dimensions of storage devices vary according to the model. Table 2-2 lists the dimensions of the related storage devices.

  • U-shaped brackets

    The distance between the front mounting bar and the inner side of the front door varies according to the cabinet type. Because the system enclosure is fixed on the front mounting bars, a longer distance between the front mounting bars and the inner side of the front door can result in smaller space for cabling at the rear of the device. In such a case, you can install U-shaped brackets to move the system enclosure forward and leave more space at the rear of the device for cabling.

    A U-shaped bracket is a mechanical part installed between the mounting ear of the enclosure and mounting bar of the cabinet to adjust the relative position between the enclosure and the cabinet. A maximum of two U-shaped brackets can be stacked.

    U-shaped brackets are classified into three types: 25 mm, 50 mm, and 75 mm, as shown in Figure 2-2, Figure 2-3, and Figure 2-4.

    • If U-shaped brackets are not installed, the system enclosure is fixed to the front mounting bars by using captive screws. The distance between the front panel of the system enclosure and the inner side of the front door is fixed.
    • Install the U-shaped brackets on the front mounting bars, and then secure the system enclosure to U-shaped brackets of the respective size. This allows you to adjust the distance between the front panel of the system enclosure and the inner side of the front door within a certain range.

Cabinet Space Requirements

Before installing storage devices in a cabinet, ensure that:

• The cabinet front door can be properly closed without touching the front panel of the system enclosure.
• The distance between the rear of the system enclosure and the rear door of the cabinet is greater than or equal to 90 mm. An insufficient distance will cause difficulties in routing cables or closing the rear cabinet door.

If the distance between the front mounting bars and the inner side of the front door does not meet the installation requirements, use U-shaped brackets to shorten the distance between the front panel of the system enclosure and the inner side of the front door. Figure 2-5 and Figure 2-6 show the positions of the storage system before and after the U-shaped brackets are installed.

• Use the measuring scale in the auxiliary material package to determine the type of U-shaped bracket for your storage device. Follow the instructions on the measuring scale.
• For details on how to install the U-shaped brackets, see (Optional) Installing U-shaped Brackets and Adjustable Guide Rails.
• The U-shaped brackets shorten the distance between the front panel of the system enclosure and the inner side of the front door (L1 in the figures) to increase the distance between the rear of the system enclosure and the rear door of the cabinet (L2 in the figures).

The preceding cabinet space requirements do not consider the space that may be contained in the front and rear doors of the cabinet.
