Campus · Multi-site
A structured access and distribution design for headquarters, branches, and smart buildings — with predictable PoE, quieter closets, and port-level visibility.
Operators running dozens of branch sites need a repeatable campus blueprint: core and distribution roles that scale without forklift upgrades, access layers that respect WLAN and video PoE budgets, and operational playbooks facilities teams can run without deep CLI expertise.
This reference design maps EtherNexion switching platforms to a classic headquarters-to-branch topology — with stacking-friendly access, resilient uplinks, and API-first day-2 workflows aligned to your existing NMS and automation toolchain.
Centralized management with distributed access — designed for growth sites, video endpoints, and WLAN density.
Single operational view from core to access — port, PoE, and health state without per-site tool sprawl.
WLAN and video-friendly power budgets with clear per-port policies before change windows.
Streaming telemetry and northbound APIs for staged rollouts, config baselines, and audit-friendly change control.
A facilities-led team standardized access closets across regional offices — reducing truck rolls with remote PoE diagnostics, stacking templates per building size, and a single support entry for escalation. The playbook below is the same pattern we document for EtherNexion campus deployments.
Operations
Stacking and uplink patterns that absorb site growth without redesigning every closet.
Dual-homed distribution and ring-friendly access for branch survivability.
Shared BOM lines and firmware trains across site tiers.
Per building-size presets — from wiring closet to IDF.
PoE classes and port policies aligned to AP density.
Lifecycle
From staging to production — baselines, telemetry, and support workflows that match how facilities teams actually operate.
Maintenance rings with signed images and rollback notes.
GPU-free campus metrics for NMS and automation hooks.
Role-based access patterns for guest, IoT, and corporate VLANs.
Runbooks for PoE validation, stacking, and escalation.
Building blocks your teams can standardize across headquarters, branches, and smart-building endpoints.
Access and distribution stacking patterns with clear growth headroom.
Per-port budgets for APs, cameras, and badge readers.
gNMI-friendly exports for your observability stack.
Northbound hooks for provisioning and audit trails.
Guest / IoT / corporate separation without CLI sprawl.
GA and maintenance rings with documented rollback.
