48 portový L2 managed 1Gbit switch | D-Link DGS-3048 |
Kategorie:
Síťové prvky
Prodám rackový switch (19“), nebyl prakticky nikdy používaný. Koupen pro domácí síť se servrem: projekt, od kterého jsem nakonec upustil. Původní cena 40 tisíc, nyní se již nikde neprodává. Možnost osobního předání v Praze či zaslat zásilkovnou
