The Ethernet switch cards can be installed on any IPC motherboard with PCI or PCIe socket. They enable an IPC or embedded system to communicate with other Ethernet devices, such as IP cameras. The switch cards also connect the 4 ports on the card to each other without placing a load on the PC or having to provide routing functions. This makes an external switch superfluous. One port leads internally to the PC, 4 ports can be connected externally.
