Ethernet Communication and VMEbus Interface
The IS215UCVGH1AB provides two Ethernet ports for controller communication and configuration access. The primary interface connects to the User Data Highway (UDH) for Toolbox configuration and data exchange. The second interface supports additional network communication according to the system configuration.
The supplied specifications identify TCP/IP, Ethernet Global Data (EGD), and Ethernet Modbus as supported communication methods. Actual protocol availability and port assignments depend on the installed firmware and controller configuration.
The board connects to the VMEbus backplane for data exchange and receives power through the chassis. The available information does not specify its power consumption, backplane current requirements, or supported hot-swap behavior.
Frequently Asked Questions
Q: Which processor and memory configuration does the IS215UCVGH1AB use?
A: It uses a 650 MHz Intel Ultra Low Voltage Celeron processor, 128 MB of flash memory, and 128 MB of SDRAM.
Q: Which Ethernet interfaces are available on this board?
A: The board has two RJ-45 Ethernet interfaces specified for 10BASE-T and 100BASE-TX connectivity. Confirm protocol assignments against the installed firmware and system configuration.
Q: Can the IS215UCVGH1AB be replaced while the controller is energized?
A: Hot-swap support is not established by the supplied specifications. Follow the applicable GE Mark VI maintenance procedure and isolate power as required before removing or replacing the board.
Field Installation Guidelines
- Verify the complete part number, IS215UCVGH1AB, and board revision before installation.
- Confirm compatibility with the target Mark VI chassis, VMEbus backplane, firmware, and controller configuration.
- Follow site electrostatic discharge (ESD) precautions when handling the circuit board.
- Inspect the board connector and backplane interface for damage, contamination, or bent contacts before insertion.
- Seat the board in the designated slot according to the equipment maintenance documentation. Do not force the connector into position.
- Route Ethernet cables away from high-voltage conductors and high-noise switching circuits where practical.
- Check RJ-45 cable connections, link status, IP configuration, and communication settings during commissioning.
- Verify UDH connectivity and configured data exchange before returning the controller to service.
- Confirm power isolation and approved maintenance procedures before removing the board. Do not assume hot-swap capability without manufacturer documentation.
