Abstract

An easy to engage and disengage dual height card retainer that facilitates removal of daughterboards is disclosed. Daughterboards have a two-tier staggered arrangement above the motherboard. Each daughterboard has a signal transfer end that electrically connects to the motherboard through one of the dual height bus connectors, and a back panel connector end that couples to the back panel with an accessory connector or with a filler panel that functions as an electromagnetic interference shield. Dual height card retainers that require no tools to operate function as retaining means to prevent daughterboards from working lose from bus connectors during shipment.
