Cena z VAT 23% - Wystawiam fakturę.

W pełni profesjonalny przełącznik. Zarządzany (L2). Podobny sprzęt innych marek potrafi kosztować nawet 5.000 - 8.000 zł.
Polecam.

Przełącznik używany był około 8 miesięcy i od ponad roku leży nieużywany.

Gwarancja jest na 5 lat lub wieczysta z wymianą w razie awarii na nowy. Jednak nie jestem w stanie ustalić dziś szczegółów. Najłatwiej będzie ustalić to w Dlink.
