Installing a crossbar fabric module

Use this information to install a crossbar module in an IBM c-type SAN device.

Before you begin

You must follow ESD protocols, including the following:

  1. You must wear a grounded ESD wristband (or other personal grounding device) whenever you handle the electronic modules outside the grounded chassis.

  2. You must carry electronic modules by only their covered edges or handles. Do not touch their electronic components.

  3. Whenever a module is outside a grounded chassis, place it flat on an antistatic surface or in an antistatic bag. Never lean the module on anything nor place anything else on top of the module nor lean anything on the module.

    • Verify that the chassis is grounded.
    • Verify that you have the following tools and equipment:
      1. ESD wrist strap (or other personal grounding device).
      2. Number 1 Phillips torque screwdriver.

      3. Manual torque screwdrivers are recommended. Be sure to never exceed the recommended torque setting for the screw that you are working with.

    • Ensure that sufficient quantity of Crossbar Fabric-3 Switching Modules (6 modules are supported in a IBM SAN c-type Director switches) are available for replacing the current Crossbar Fabric Switching Modules in the switch.

About this task

Warning:

It is not supported to mix different crossbar fabric switching modules (Crossbar Fabric-1 Switching Module and Crossbar Fabric-3 Switching Module) outside a maintenance window. This mix of modules is supported only while you are migrating from Fabric-1 modules to Fabric-3 modules. After a reboot of the switch, if there is a mix of Fabric-1 and Fabric-3 modules, only the Fabric-3 modules will be powered on.

Warning:

Ensure that there is no loose debris (such as paper, ties, dust) around the back of the chassis when the crossbar switching modules are being removed. When the crossbar switching modules are pulled, the vacuum created can be strong enough to pull the loose debris into the chassis.

Procedure

To install a crossbar module in the IBM c-type SAN Device, complete the following steps.

  1. Before installing any modules, install at least one Supervisor-1 module.
  2. Remove the fan module that is over the crossbar fabric module to be removed. For more information on how to remove a fan module, see Removing a crossbar fabric module
  3. Open both ejector levers on the new or replacement module completely by pressing on the ejector release buttons located at the middle of the module.
    CAUTION:
    You must allow enough space for the ejector levers to open 90 degrees to avoid potential injury.
  4. Position the module in the chassis as follows:
    1. Position the module in the slot. Rest the module on the chassis and ensure that the module is within the slot guides.
    2. Push the center of module face plate to slide the module inside the slot.
    3. Keep pushing in the module slowly into the chassis until its rear connectors touch the mid-plane surface. Visually inspect if the ejector claw is within the U channel bracket inside the chassis.
    4. After the ejector jaw is in the correct position, grasp the ejector levers and rotate them simultaneously inward until the ejector levers are flush with the face plate.
      CAUTION:
      Be careful not to pinch your fingers as the ejector levers are rotating into locking position.
    5. While pressing down, simultaneously close the ejector levers to completely seat the module in the midplane connector. The ejector levers are completely closed when they are flush with the front of the module.
  5. Install the fan module that you removed earlier. For more information on how to install a fan module, see Installing and Removing Fan Modules.
