Installing the Switch

Before you begin

  • You need to slide the chassis onto the bottom-support rails so that the end with the fan trays and power supplies locks onto the chassis stops at the end of the rails and so that the front-mount brackets on the chassis come into contact with the front-mount rails on the rack.

  • Make sure that the four-post rack is properly installed and secured to the concrete floor.

  • Make sure that the bottom-support rails are installed so that the power supplies and fan trays will be in the appropriate aisle.

  • The color of the stripe on fan trays and the color of the latch on power supplies determines which end of the switch must be positioned in the cold aisle as follows:

    • If the modules have burgundy coloring, position the port end of the chassis in the cold aisle.

    • If the modules have blue coloring, position the fan trays and power supply end of the chassis in the cold aisle.

  • Make sure that two front-mount brackets are securely fastened to the sides of the chassis at the port end.

  • Make sure that you have two customer-supplied rack-mount screws (M6 x 10 mm or appropriate screw for the vertical mounting rails on the rack).

About this task

To install the switch, perform the following steps:

Procedure

  1. Slide the power supply and fan tray end of the chassis onto the bottom support rails that are installed on the rack.

    Be sure that the sides of the chassis by the fan trays and power supplies clips onto the chassis stops on the bottom support rails and the front mounting brackets come in contact with the rack (see the following figure).

    If the bottom support rails are extended a long distance, they can bend outwards slightly when you install the chassis, and the chassis stops at the far end of the rails might not fit into the end of the chassis. If this happens, press the side rails toward the sides of the chassis so that the chassis stops can go inside the chassis and hold it in place on the rack.

    3 Customer-supplied rack-mount screw (M6 x 10 mm screw or other appropriate screw) used to secure each side of the chassis to the rack.
  2. Use a customer-supplied rack-mount screw (an M6 x 10 mm screw or other appropriate screw for the rack) to attach each of the two mounting brackets on the chassis to the rack and tighten each screw to the appropriate torque setting for the screw (for M6 x 10 mm screws, use 40 in-lb [4.5 N·m] of torque).
