4x ethernet port card for G4 ???

[ArmorAlley]

This G4 looks to have a 4-port ethernet card in it.
I know that Cisco made similar cards but for the Mac?
Does anyone know about these cards and are they supported in Mac OS 9?

4 port ethernet PCI cards aren't uncommon. No idea if they work in OS 9 though - but classic MacOS doesn't have a networking model that tends to work well with lots of interfaces, so if not, it's not a big loss.
