README
README.mdHürmüz - an rpi cm4 server board
Hürmüz is a devguard slice server board using the raspberry pi compute module 4 as CPU.
Ethernet is bundled via a KSZ9477 ethernet switch, where each CPU gets its own VLAN. For recovery and management, USB is connected via an usb switch to an additional managment CPU.

Questions
How big is the Switch test board PCB?
It measures 122.8 × 102.7 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Switch test board use?
205 parts, built around the KSZ9477STXI, LD39200PUR, MDT420M02001 and MIC826TYM-TR. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Switch test board KiCad files?
From the devguardio/hurmuz repository on GitHub, at the commit this page was made from: the board is switch-test-board/switch-test-board.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Switch test board design in my own project?
Its repository states no licence, so its author keeps all rights: ask devguardio before reusing the design.
