Concentrator Workshop and Control-Room Aggregation

Concentrator control-room MDFs aggregate shop rings and terminals on rack aggregation switches.

1. Scenario

Shops to control room mix OT and IT—need clear aggregation and isolation.

2. Challenges

Mixed fiber/copper; port exhaustion on expansion; one NMS.

3. Architecture

8GE at shops; 24GE/26GH in control MDF; strict OT/IT split before plant core.

4. Recommended Leagrid LGS2000 products

  • LGS2000-24GE4GF-M: Managed rack aggregation: 24×GE copper + 4×GE SFP for station/central-room aggregation.
  • LGS2000-26GH-M: Managed hybrid-port aggregation (fiber/copper/Combo) for mixed cabling and expansion.
  • LGS2000-8GE2GF-M: Managed Gigabit industrial switch: 8×GE copper + 2×GE SFP; VLAN/QoS/ring redundancy for intersection and shop-floor aggregation.

5. Deployment notes

No L2 OT↔IT bridge; change windows off continuous production; spare optics/PSUs.
