  • Publication number: 20210390985
    Abstract: A chassis for housing a computing device of an information handling system includes a receiving portion of an expansion card receiver that receives an expansion card and operably connects the expansion card to another component of the computing device while the expansion card is received by the receiving portion. The chassis further includes a management portion of the expansion card receiver that receives a force from a user and, in response to receiving the force: transitions the management portion from a first state to a second state. In the first state, a handle, that enables the expansion card to be removed from the chassis is disposed inside of the management portion and the expansion card receiver is locked to the chassis. In the second state, the handle is disposed outside of the management portion and the expansion card receiver is unlocked from the chassis.

  • Patent number: 10212837
    Abstract: A divider for a bay of a blade server chassis includes a plurality of posts, a plurality of flex tabs, and a rail. The posts are located along a first side of the divider, and are configured to be inserted within respective holes in a first panel of the bay of the blade server chassis. The flex tabs are located along a second side of the divider, and are placed in physical communication with a second panel of the bay. The flex tabs are configured compress within the divider and away from the second panel to enable the posts to be inserted in the holes of the first panel, the second side of the divider being opposite to the first side of the divider. The rail is located along a third side of the divider, and is configured to guide a blade server within the bay.

  • Patent number: 10172252
    Abstract: An information handling includes a plunger that secures a server planar board within the information handling system. The plunger includes a nut, a body, a rod, and a cap. The nut tightens toward the body and holds the server planar board between the nut and the body. The rod securely holds the server planar board within the information handling system in response to the plunger being in a locked position, and enables the server planar board to be removed from within the information handling system in response to the plunger being in an unlocked position. The cap includes a handle to provide a surface for a force to be exerted to cause the plunger to move from the locked position to the unlocked position.
