Selection Suggestions
-
Assess network requirements – Select the DS200SLCCG1ACC if you need maximum network connectivity (4 Ethernet, 4 fiber) with link aggregation, load balancing, and conformal coating protection.
-
Assess environmental conditions – The board is essential if your installation is harsh (coastal, offshore, chemical, high-humidity).
-
Evaluate redundancy requirements – The board is ideal if you need redundant communication paths and link aggregation for critical data links.
-
Confirm protocols – Ensure the board supports the required protocols (MODBUS TCP, DNP3, IEC 61850, IEC 61850-90-5, OPC UA, MQTT, REST API).
-
Check slot availability – The board requires 1.5-slot clearance. Verify adjacent slot is empty.
-
Procurement – The DS200SLCCG1ACC is exceedingly rare. Only purchase from suppliers providing coating verification, port testing, network validation, link aggregation testing, and LED testing. Lead times: 30-36 weeks.
-
Stock spares – Maintain at least one spare on-site.
Important Precautions
-
Power down completely – Hot-swapping is not supported.
-
Slot clearance – Ensure 1.5-slot clearance (adjacent slot empty).
-
ESD protection – Use wrist strap and anti-static mat.
-
Cable routing – Route communication cables away from high-voltage power cables.
-
Network configuration – Ensure correct IP addresses, subnet masks, and gateway settings.
-
Link aggregation configuration – Configure link aggregation (IEEE 802.3ad) settings.
-
Redundant path configuration – Configure redundant path management settings for critical communication links.
-
Coating integrity check – On power-up, verify white “COAT OK” LED illuminates. If off, remove and return for recoating.
-
Pre-failure WARN LED – If amber WARN LED illuminates, investigate immediately.
-
Cleaning – Use only dry compressed air (max 50 PSI, 30 cm distance). No solvents, alcohol, or brushes.
-
Storage – Store at 10-30°C, 20-50% RH. Rotate every 3 years.

For most applications, the DS200SLCCG1ABA (2 Ethernet, 2 fiber, coated) provides excellent LAN communication capability at lower cost and 1-slot form factor. The DS200SLCCG1ACC should be reserved for the most demanding LAN communication applications requiring maximum connectivity and advanced features.
When sourcing, ensure comprehensive documentation – coating verification, port testing, network validation, link aggregation testing, and LED testing. Given its exceedingly rare availability, maintain at least one spare on-site. Properly deployed, this board provides years of reliable LAN communication for Mark V turbine control systems in the most challenging environments.
