EXNET-ONE Card Software Functions

The EXNET-ONE card is responsible for the following functionality:

• System Monitoring

• Diagnostics

• Ring Control

• Ring Configuration

• Ring Switching

• Inter-Board Communications

The EXNET-ONE card requires system software Release 5.5 or later version. The system software treats the EXNET-ONE card as a line interface card. When the system software detects an EXNET-ONE card (when the system powers up or when the EXNET-ONE is hot-inserted), it notifies the host using the Card Status Report (0xA6) message. At start-up, the system software recognizes the EXNET-ONE card’s unique ID and begins a card start sequence downloading the applicable EXNET-ONE system software. At this point, the ROM resident code is running on the EXNET-ONE card as it begins execution.
