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.
