# Network Topology Diagram **Current diagram saved:** `_attachments/network-topology-diagram.png` ## Three-Location Network Architecture The RAT network infrastructure connects three physical locations: ### FTMA Building (Entry Point) - **SFP Panel** - Fiber optic connection point - **Patch Panel** - Copper patch connections - **Cisco Internet Switches** - WAN entry and initial routing ### IDF Room (Distribution Hub) **Main switching and routing location** - **SFP Panel** → Connected to Machine Room via fiber - **Patch Panel** → Local copper connections - **Ubiquiti Gigabit Network Switch (Dante)** → Dedicated Dante audio network - Connected to 850 D1-16 (or 900 D1-16? - needs verification) - **Cisco 3850 Switch** (primary) - **Cisco 3850 Switch (internet)** - WAN-facing switch - **Cisco 3850 Switch** (tertiary) - Purpose unclear - **Ubiquiti Router** - Primary router (likely public/private network boundary) **Fiber connections to Machine Room:** - 850 D1-15 and D1-16 noted in diagram - 900 D1-16 and D1-18 also mentioned (conflicting labeling - needs physical verification) ### Machine Room (Equipment Location) **High-bandwidth equipment and storage** - **Dante Uplink** → To Dante network in IDF Room - **NDI** connection → Video over IP - **Internet Uplink** → High-speed internet connection - **NAS** → Network-attached storage (connects to Computer and SSL) - **Computer** → Connected to NAS - **SSL** console → Connected to NAS - **Netgear 10 Gigabit Switch** → High-speed switching for audio/video equipment ### Legacy Equipment Section Equipment that may be in use or being phased out: - **PoE Switch** - **D-Link Web Switch** - **SSL Switch** ## Key Infrastructure Questions ### 1. SFP Label Discrepancy **Issue:** Diagram shows conflicting labels - IDF Room connections labeled: 850 D1-15 and 850 D1-16 - Annotation states: "850 D1-15 and D1-16 are in machine room. I think 850 D1-16 is mislabeled as 900 D1-16" - Another annotation: "900 D1-16 and D1-18 are in machine room. I think 850 D1-16 is mislabeled as 900 D1-16" **Action needed:** Physical verification of actual fiber labels in both IDF Room and Machine Room ### 2. Public/Private Network Boundary **Question:** Where does internet transition from public to private? **Hypothesis:** Ubiquiti Router in IDF Room is the boundary point - **Upstream (public):** Cisco Internet Switches handle WAN connection - **Downstream (private):** All IDF Room and Machine Room equipment on private network **Needs confirmation:** - Router configuration review - IP address scheme documentation - NAT/firewall rules verification ### 3. Cisco 3850 Switch Roles **Three Cisco 3850 switches in IDF Room:** 1. One labeled "internet" - Likely upstream to WAN 2. Two others - Purpose unclear (redundancy? VLANs? separate network segments?) **Action needed:** - Document port assignments for each switch - Identify inter-switch connections - Determine if running spanning tree or stacking protocol ### 4. 10G Connectivity **Netgear M4300-52G-PoE+ specs:** - 2 x 10G Ethernet Ports - 2 x 10G SFP+ Ports **Question:** How are these being used? - SFP+ to IDF Room via fiber? - Direct connections to NAS? - Dante network uplinks? ## Network Segments (Hypothesis) Based on equipment, likely network segments: 1. **WAN Segment** - Cisco Internet Switches to Ubiquiti Router 2. **Management Network** - Switch management interfaces 3. **Dante Audio Network** - Isolated on Ubiquiti Dante switch 4. **General Infrastructure** - NAS, computers, SSL console 5. **High-Speed Production** - 10G connections for media transfer **Needs verification:** VLAN configuration, IP schemes, routing between segments ## Diagram Reference ![[network-topology-diagram.png]] ## Next Steps 1. Physical site survey - verify all equipment locations and labels 2. Document IP address schemes for each segment 3. Review switch configurations - port assignments, VLANs, routing 4. Resolve SFP labeling discrepancy 5. Create detailed connection map with cable IDs 6. Document the public/private network boundary explicitly
