Installing the Switch

This section describes how to use the rack-mount kit to install the IBM SAN50C-R switch into a cabinet or rack that meets the requirements described in the Rack Requirements section.
Explanation point
CAUTION:
If the rack is on wheels, ensure that the brakes are engaged or that the rack is otherwise stabilized.
Explanation point
CAUTION:
If connecting a IBM SAN50C-R switch to a 110-VAC power system, ensure that sufficient power is provided to meet the chassis power requirements for the number of modules installed. If the rack is on wheels, ensure that the brakes are engaged or that the rack is otherwise stabilized.

Warning: When installing or replacing the unit, the ground connection must always be made first and disconnected last.
Explanation point
CAUTION:
All power supplies must be grounded. The receptacles of the AC power cables used to provide power to the chassis must be the grounding type, and the grounding conductors should connect to protective earth ground at the service equipment. For a IBM SAN50C-R switch with a DC power supply, a grounding cable must be connected to the terminal block.

If a 110-VAC input is chosen, order a 110-VAC power cord separately. Table 1-1 lists the items provided in the IBM SAN50C-R mounting kit used for installing the switch.

To install the IBM SAN50C-R chassis in a rack using the mounting kit provided with the switch, follow these steps.
  1. Install the front rack-mount bracket as follows:
    1. Position one of the front rack-mount brackets against the side of the switch and align the screw holes as shown in the following graphic.

    2. Attach the bracket to the switch with the four M4 screws originally provided with the bracket.
    3. Repeat with the other front rack-mount bracket on the other side of the switch.
  2. Install the C brackets as follows:
    1. Attach the bracket to the switch with the two M3 screws originally provided with the bracket.

  3. Install the slider rails in the rack. Position one of the slider rails against the rack mounting rails and align the screw holes.

  4. Attach the slider rail using four 12-24 screws or four 10-32 screws, depending on the rack rail thread type. For racks with square holes, insert the 12-24 cage nuts in position behind the mounting holes in the slider rails.
    1. Repeat with the other slider rail on the other side of the rack.
    2. Use the tape measure and level to verify that the rails are horizontal and at the same height.
  5. Insert the switch into the rack as follows.

    1. Use both hands to position the switch with the back of the switch between the front rack-mounting rails.

    2. Align the two C brackets on either side of the switch with the slider rails installed in the rack. Slide the C brackets onto the slider rails, and then gently slide the switch all the way into the rack. If the switch does not slide easily, try realigning the C brackets on the slider rails.
  6. Stabilize the switch in the rack by attaching the front rack-mount brackets to the front rack-mounting rails.
    1. Insert four screws (12-24 or 10-32, depending on rack type) through the cage nuts and the holes in one of the front rack-mount brackets and into the threaded holes in the rack-mounting rail.

    2. Repeat for the front rack-mount bracket on the other side of the switch.

      If you are installing the optional cable guides, place the cable guides in front of the front rack-mount brackets, and then pass the screws through the cable guides, front rack-mount brackets, and mounting rail. You can install one or both cable guides; if installing a single cable guide, it can be installed on either side.
