6.Move your head slightly right to the next connector, and inspect its pins, repeating Step 4 and Step 5.

7.Continue in this manner for each connector until you reach the right side of the fabric card.

Inspecting the Fans

The fans of the fabric card are FRU components. The fans secure in position with two thumbscrews.

1.Ensure that each fan is seated properly in the fabric card.

2.Ensure that both thumbscrews are tight on each fan.

Inspecting the Retainers

The two retainers on the fabric card serve three purposes:

Align the fabric card for proper insertion into the chassis.

Allow final insertion of the fabric card into the chassis and simplify the physical connection of the fabric card connectors to the midplane connectors.

Allow extraction of the fabric card from the chassis and simplify the physical disconnection of the fabric card connectors from the midplane connectors.

The retainer’s design is shown in FIGURE 6-2.

Ensure that the pieces of the retainer look finished, move smoothly, do not bind, or do not feel loose or sloppy in any way.

See FIGURE 6-2.
