Circuit Card Ejector Tab or Built-in Thumb Hold

Most circuit cards have an ejector tab that is used to assist the installer in inserting and removing each circuit card. These ejector tabs are typically located at either the top or bottom of the circuit card. Other types of circuit cards have a built-in thumb hold for gripping the card. Follow the procedure given to remove and insert a circuit card.

Removing Circuit Card

DANGER

ATTENTION

Contacting circuit card components or traces can result in an electrical shock even after removal from the shelf.

Wear properly grounded anti-static wrist-straps when removing a circuit card. At all other times (shipping, storage, and so on) keep the circuit cards in their protective bags.

Step

Action

1

Remove any front-panel cables from the circuit card.

 

Note: Note the positions of all cables and slots each circuit card resides in for later replacement.

2Grasp the circuit card at the top or bottom ejector tab or the built-in thumb hold and pull forward to release it from its connection. A slight amount of force may be required to unseat the circuit card.

Inserting Circuit Card

ATTENTION

Wear properly grounded anti-static wrist-straps when inserting a circuit card. At all other times (shipping, storage, and so on) keep the circuit cards in their protective bags.

Step

Action

1Holding the circuit card by its ejector tab or built-in thumb hold, insert into the shelf housing. Ensure that the circuit card connection is firmly seated.

2Attach any front-panel cables to the circuit card.

Note: To prevent confusion, it is sometimes important for the installer to note in which slot each circuit card resides and in which connector each cable resides.
