7.6 Installing Line Cards
This procedure describes how to install one line card as part of a replacement
operation. If you are installing more than one line card, repeat the procedure for
each line card. Alternatively, refer to the Sun Datacenter Switch 3456 Installation Guide.

Installing the line card is a two-person task, as both people must work in a
synchronized manner. To prevent damage to the line card or the pins of the
midplane connector, the two installers perform identical tasks simultaneously.
1. Extend the antitilt bar from the bottom of the switch chassis.
2. Unwrap the line card from its antistatic packaging.
3. Inspect the connectors and retainers.

counter-clockwise until resistance is felt.
6. Rotate both the retainer drive screws clockwise, 1/4 turn.
