Two pieces of metal, one cast and one sheet, two sets of LAN terminals, an USB, SFP, and some other connectors, plus a printed board with some chips on it.
Always funny when some random guys know things better. The shortage affects especially "simple" chips. Like small uCs, voltage controllers and similar.
To give you an example:
My employer is waiting for 30'000 simple micro controllers (normally 2$/pcs). We ordered them in January 2022, for 7$/pcs.
Initial shipping date was August 2022. Than it was moved to March 2023. Today, it was moved to August 2023.
The affected product is much simpler than a RB5009. But without the micro controller, it cannot be built.
