Installing Fabric Cards Into the Chassis

▼ To Install the Midplane Stiffener

Note – The midplane stiffener must be installed before the fabric cards are installed.
Installing the midplane stiffener is a two-person task, as both people must work in a
synchronized manner. To prevent damage to the pins of the midplane connector, the
two installers must carefully align the stiffener with the midplane crossbar.
1. Place the stiffener on a work surface, with the retainers facing the two
installers.
2. Using a 17 mm socket and ratchet, turn each retainer drive screw fully
counter-clockwise until resistance is felt.
3. Rotate both the retainer drive screws clockwise, 1/4 turn.
4. Lift the midplane stiffener from the work surface and insert the stiffener into
the chassis at slot 11.
Ensure that the stiffener is perpendicular to the surface of the midplane. See
