Installing an SCE

Scenarios

Install a system compute enclosure (SCE) if:

  • Another SCE is required in the cabinet for capacity expansion.
  • An SCE in the cabinet has failed.
Impact on the System

This operation has no adverse impact on the system.

Prerequisites

Conditions

Data

No data preparation is required for this operation.

Tools

  • ESD gloves or ESD wrist strap
  • Phillips screwdriver
Procedure
  1. Plan the SCE installation position.

    • Figure 3-80 shows the positions for installing floating nuts.
    • The lower four square holes shown in Figure 3-80 are reserved for installing SCE guide rails.
    Figure 3-80 SCE installation position

  2. Install floating nuts.

    1. Determine the positions for installing floating nuts according to the installation plan.
      NOTE:

      Floating nuts are used to tighten screws.

      The middle of two adjacent square holes with small spacing is the boundary of two Us, as shown in Figure 3-81. The boundary between Us is used as the reference for calculating device installation space.

      Figure 3-81 Spacing of 1 U on a mounting bar of a cabinet

    2. Fasten the lower end of a floating nut to the target square hole in a mounting bar at the front of the cabinet. See Figure 3-82.
      Figure 3-82 Installing a floating nut

    3. Use a floating nut hook to pull the upper end of the floating nut, and fasten it to the upper edge of the square hole.

  3. Install adjustable guide rails. See Figure 3-83.

    1. Place a guide rail horizontally in the planned position, and keep the guide rail in close contact with mounting bars. See steps (1) and (2) in Figure 3-83.
    2. Tighten captive screws to secure the guide rail. See steps (3) and (4) in Figure 3-83. Then install the other guide rail in the same way.
    NOTE:

    The meanings of the identifiers on the inner sides of a guide rail are as follows:

    • F/L: indicates that the guide rail needs to be installed on the left of the cabinet, and the end marked with the identifier is the front of the guide rail.
    • F/R: indicates that the guide rail needs to be installed on the right of the cabinet, and the end marked with the identifier is the front of the guide rail.

      An adjustable guide rail is 680 mm (26.77 in.) to 920 mm (36.22 in.) long, and it can be installed in a cabinet with a column distance of 689 mm (27.13 in.) to 929 mm (36.57 in.), including the widths of the columns.
