PVP cards come standard with a front panel installed. This is referred to in the PCI Express standard as an "I/O Bracket", and serves to affix the PVP card when installed in the customer's host computer system. In most computer chassis designs, PCI Express slots are oriented with cards facing the rear when installed. The front panel for the PVP card can thus be accessed from the rear of most chassis, providing access to the receiver connectors. A Virtex-6 PVP card occupies a standard height, full-length PCIe slot, whle a Virtex-7 PVP card occupies a standard height, half-length PCIe slot.
