Abstract:
1. A chassis and card system, comprising: a chassis having a slot for receiving a card and having an Ethernet bus for receiving packets from the card and sending packets to the card and having a power supply with a power strip for supplying power to the card; a card with a processor and an Ethernet input/output for sending packets over a local network and for receiving packets from the local network, said Ethernet input/output including: a controllable backplane interface to said Ethernet bus with a switch normally active to direct data flow between said card and said chassis Ethernet bus, an Ethernet transceiver connectable to the local network; and an Ethernet link signal detector for detecting an Ethernet link signal at said Ethernet transceiver and deactivating said switch to isolate the card from the Ethernet bus and to force data flow through said Ethernet transceiver.
