Install an IOU

1. Use an antistatic wrist strap to protect the equipment from ESD damage.
2. Transfer the grey plastic connector covers from the new IOU to the old IOU.

   Squeeze the edges of a cover to release it from the connector.

3. Install the new IOU.
   1. Loosen the captive screws on the two extraction levers
   2. Fully open the extraction levers.

      ---

      Caution - The open extraction levers might slip down to eye level and pose a danger. Keep the levers closed and locked whenever possible.

      ---

      
      
   3. Slowly slide the IOU into its slot.

      Keep the IOU as perfectly vertical as possible.

      When the IOU is almost completely into the slot, stop when you feel some resistance.

      ---

      Caution - There is a danger of bending pins in the connector at the back of the IOU. Do not hold the IOU at an angle when inserting it into the slot.

      ---

   4. Complete the insertion by closing both extraction levers at the same rate so that they both completely close at the same time.

      ---

      Note - Because of the large number of connector pins at the rear of the IOU, it is normal to feel a larger than normal resistance as you seat the IOU. If you are not sure that you inserted the IOU at the proper angle (exactly 90° to the midplane), pull the IOU out and inspect the connector sockets and pins for damage. If there is no damage, try inserting the IOU again.

   5. Use a T25 Torx screwdriver to tighten the captive screws on the extraction levers.

      Tighten the screws to 15 in-lb. See Torque Reference.

4. Fill the IOU slots.

   Note - Install all components in their original locations.
