- `riser_fiber_m`: 300 (6 risers × 50 m avg)
- `transceiver_qty`: 14 (paired)
- `vlan_strategy`: flat /24 BMS subnet (per A-NET-003)
- `ip_subnet`: 10.10.50.0/24 (per A5)
- `ip_uplink_to_customer`: TBD (per Q-012)

## BOQ line items (Phase 6 input)

| WBS | Description | Qty | Unit | Reference |

| 2.2.1 | Core switch UPS (within head-end UPS, no separate item) | — | — | counted in head-end |
| 2.2.2 | Managed L2 edge switch — 16-port (SW-GND, SW-2F, SW-RD) | 3 | each | A5 |
| 2.2.2 | Managed L2 edge switch — 8-port (SW-LZ, SW-3F, SW-BSMT) | 3 | each | A5 |

## Open assumptions for this instance

- A-NET-001: 1 Gbps fiber backbone, OM3 multimode (sufficient for BMS data)
- A-NET-002: 6 edge IDFs (one per floor/zone) — verify with Q-005 architectural
- A-NET-003: flat /24 BMS subnet (no VLAN segmentation in base)
- A-NET-004: Edge switches managed L2 only
- A-NET-005: UPS protection only for CORE + servers (edge switches optional in OPT)

## Cross-references

- **Working docs:** A5 (network architecture + switch schedule), A1 (Network rows = 27 drops), A4 (panel mgmt drops = 18), A7 (switch power)
- **Assumptions:** A-007 (isolated BMS LAN), A-NET-001..005
- **Clarifications:** Q-005 (architectural — edge IDF locations), Q-012 (integration scope), Q-013 (brand)
