Embodiment Construction

[0017]The present invention addresses the needs described above. The invention provides an apparatus and a method for locking a cam lever that positions a second card as inserted into a first card, and activating the second card with a single coupling member.

[0018]The invention is applicable to any situation where there are two cards that communicate with each other, and it is desirable to control the order in which a second card is inserted and activated, or deactivated and removed relative to a first card. However, for ease of explanation and clarity of the description, the discussion that follows will deal with a typical scenario in which the first card is a motherboard and the second card is a daughter card.

[0019]First and second guides are secured to a motherboard on opposite or opposing sides of a connector on the motherboard that is designed to accept the insertion of a daughter card for electronic communication therebetween. A hinged cam lever is disposed on the guide to pos...

Abstract

An apparatus and a method for locking a cam lever which positions a second card as inserted into a connector on a first card, and activating the second card with a coupling member. In one embodiment, the second card is inserted between a pair of guides secured to the first card into a connector on the first card. A hinged cam lever on either a guide or the second card positions the second card. A coupling member on the cam lever can be moved to lock the cam lever in place and engage a switch on the second card to activate the second card. When removal of the second card is desired, the coupling member on the cam lever can be moved to unlock the cam lever and disengage the switch on the second card to deactivate the second card.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to the safe insertion and removal of hot-swappable computer components.[0003]2. Description of the Related Art[0004]Hot swappable components have become commonplace in computer systems. Server systems often use hot swappable memory, hard drives, and various pieces of hardware commonly referred to as daughter cards. Hot swapping may involve the removal of a piece of hardware, or the insertion of a piece of hardware, or both while the computer is on and functioning.[0005]Computer systems that support hot swapping need some ability to detect that a component has been removed or inserted and to determine what resources are available for use. Notifying the system that a component has been inserted or removed allows for efficient allocation of resources and the use of computing power.[0006]In addition, all connections need to be designed such that neither the component nor the user can be injured...
