Model 2134 is a complete expansion system consisting of a universal PCI host card, a micro ATX mini-tower enclosure with an integrated controller and four available 32-bit PCI slots, a 230W power supply with 5V and 3.3V outputs, and a 2’ interconnecting cable. The unit provides a low-latency, high-throughput path to 32-bit PCI slots on a separate backplane in a standalone chassis. Each slot is master-capable, allowing peer-to-peer communication within the PCI environment. The slots support long and short form-factor PCI cards so that PCI platforms with only short form-factor slots gain the ability to accommodate long form-factor cards. The universal host card enables use of 5V and 3.3V PCI cards in the enclosure with a 5V- or 3.3V-only host power source.
