Your first topology ​

This walk-through builds a small design from scratch: one rack, a switch and two servers, cabled together and fed from a PDU. It takes about ten minutes and touches every view.

Open the app at networker.pedrojuarez.me. It opens on Rack Elevation. Your work is kept in this browser until you save it somewhere else — see Files, saving and sharing.

Just want to look around?

Download the demo design — one rack with a leaf switch, four servers and two PDUs, already cabled — and drop it onto the app. The screenshots in these docs use it.

1. Define the hardware ​

Devices are usually placed from templates — a switch model, a server chassis — so define those first.

  1. Open the Materials tab and stay on Switches.
  2. Click + New Switch. Enter a Model (for example SN4700) and a Manufacturer.
  3. Under NIC Templates, click + Add NIC. Set the label to links, the count to 32, the speed to 400G and the connector to QSFP-DD. Under port naming, set the prefix to swp and the first number to 1, so the ports are swp1…swp32.
  4. Under Power, click + Inlet and set the watts.
  5. Click Save, then the back arrow.
  6. Do the same on the Servers tab for a server with one NIC (say 2 × 100G QSFP28) and an inlet, and on the PDUs tab for a PDU with a bank of C13 outlets.

See Materials editor for every field, and how to arrange the ports on the faceplate.

2. Build the rack ​

  1. Open Rack Elevation and click Add Rack (or press 0). A 36U rack called Rack 1 appears. Select it to change its height or label in the side panel.
  2. Press 3 for the Switch tool. In the catalog bar at the bottom, click your switch template. Move over the rack: the preview shows where it lands. Click to place it.
  3. Press 1 for the Server tool, pick the server template, and click two free slots.
  4. Press 4 for the PDU tool, pick the PDU template, and place it.
  5. Press Esc to go back to selecting.

3. Cable the network ​

  1. Open Port Mapping. The devices are shown as faceplates. Press Ctrl+L to lay them out by rack.
  2. Press C for the Cable tool. Click a server port, then a switch port. A cable joins them.
  3. Click the cable (press Esc first to leave the Cable tool) to see its properties. Pick a cable template, or set material, mode and speed.

See Port Mapping for breakouts, bonds and drawing many cables at once.

4. Wire the power ​

  1. Open Power Budget. Press C — here it is the Power cord tool.
  2. Click a PDU outlet, then a server inlet. Repeat for every inlet.
  3. The legend in the bottom-left corner shows each PDU's outlets in use and its load against its capacity, and how many inlets are still unfed.

5. Review and save ​

  • Fabric Topology draws what connects to what.
  • BOM counts the hardware and cables; Export CSV downloads it.
  • Press Ctrl+S to save. Press Ctrl+E to download the design as a .dsl file you can keep in git, and Ctrl+I to see and edit it as text.
