Tunnel Portal and Monitoring Station Aggregation

Portal station MDFs aggregate in-tunnel rings and campus systems with 24-port rack uplinks to the civic center.

1. Scenario

Portal stations bridge in-tunnel rings to civic ops networks.

2. Challenges

Mix of access control, office, and EM; civic WAN addressing/bandwidth must be planned.

3. Architecture

8GE for station endpoints; 24GE/26GH aggregate tunnel rings + campus; fiber to the municipal tunnel SOC.

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

Security domains station vs tunnel; dual uplink if possible; port names align with BIM/inventory.
